refine and complete a form body.
00:06
After completing this video, you'll be able to use flatten mirror and thicken
00:12
Infusion 3 60.
00:13
Let's carry on with our trigger with
00:14
mechanics design at this point we've created the
00:17
basis for a form body and we're not going to do the entire form body.
00:21
But we do want to talk about a few more aspects of it.
00:24
The first thing that we want to talk about is how to add intricate detail.
00:28
As I mentioned,
00:29
we want to use the least number of
00:31
faces possible when we're working with foreign bodies
00:34
but there comes a time when we need to add specific detail.
00:38
That requires us to add more edges or faces.
00:41
For example, on this edge, if we want to add a crease,
00:44
we can double click this edge and we can use
00:46
the option to insert edge or even add a crease.
00:50
Now there are a couple of things that we should keep in mind
00:53
creasing an edge.
00:54
Or using something like beveling and edge will add additional
00:57
edges or maintain a hard edge between adjacent faces.
01:03
If we want to control this in a smoother manner,
01:05
it requires a little bit more hands on
01:07
approach and precision using something like insert edge.
01:11
So let's take a look at using insert edge
01:14
and from this view we're going to bring these edges close together.
01:18
When we bring the edges close together.
01:20
What we're doing is we're creating a tighter transition between the shapes.
01:24
We can hide the canvas image for now.
01:27
So as you can see what we're doing
01:29
here is we're creating a tighter transition between
01:32
the two adjacent faces and this is because if we go into box display mode,
01:37
what we have here is we've got a single edge right next to another edge.
01:42
We can manipulate these to change the way that the curvature works.
01:45
For example, if we go to modify edit form,
01:48
we can pull this edge back just a little bit and this will
01:51
affect the way in which that crease or that sharpened edge behaves.
01:56
Let's go ahead and repeat this process up here.
01:59
I'm going to double click on this edge and I'm going to use insert edge
02:04
And again from my front view double clicking the mouse wheel to fit the screen.
02:08
We're going to pull these edges relatively close together.
02:11
Now there is no specific number that will work
02:15
because this is a percentage value between other edges.
02:18
So for example,
02:22
side because there's not as much distance between these two edges.
02:26
So in general I go between about 0.52 point one and that gives me a nice tight crease.
02:31
Also keep in mind when we do this,
02:34
what we're doing is we're using the simple insertion
02:36
mode because that allows fusion 3 60 the ability to
02:40
not only insert the edge but also adjust the topology underneath.
02:44
If we go to our box display mode using Alton one,
02:47
we can make adjustments to this by scaling this
02:49
edge up and down or moving things around.
02:52
If you decide that you don't want that crease there,
02:54
it's as simple as selecting the edge and using delete on the keyboard to get rid of it.
02:58
So in this case we can maintain that smooth transition.
03:03
If we want to manually fade the crease away, this has to be done in a different manner.
03:08
For example,
03:10
we're going to select this bottom edge here and we're going to shift double
03:13
click up to here and we'll use modify insert edge Infusion 3 60 we can
03:19
create what's called a T point and this is an instance where the end
03:23
of one edge will end in the middle of another creating this T point.
03:28
Now that's perfectly okay.
03:29
But what we want to do is we want to tighten that crease up as we get further forward.
03:33
So in order to do this, I'm going to select these two edges.
03:37
Select insert edge and we're gonna put these two closer together.
03:42
Then we're going to use modify insert point and connect the two open edges.
03:49
Now, when we take a look at this using control and the number four to hide my edges,
03:53
you can see that the transition is still there but
03:56
we can control how close or how narrow it gets.
03:59
So this allows us to have a nice transition on the handle and then have
04:03
it blend away or tighten up as we get to the top of the device.
04:07
Going to use control and the number six to bring my edges back.
04:10
And you can also go to your display settings,
04:12
visual style and use shaded with visible edges only or shaded to remove the edges.
04:19
Now that we've explored ways in which we can add some additional detail.
04:22
Let's talk about mirroring this to the other
04:24
side and creating a thickened version of it.
04:27
So first we're going to go to symmetry and take a look at mirror internal.
04:31
And mirror duplicate when we create a duplicate body.
04:35
It'll create it across a plane or a selected reference when we use mirror internal.
04:40
It'll take a body that is already across that plane and it'll make it symmetric.
04:45
So in this case we're going to say mirror duplicate
04:49
and we want to select our mirror plane.
04:52
Notice here that there is a weld option
04:54
and there is a well tolerance.
04:56
What we want to see here is this green symmetry edge that happens between the bodies.
05:02
This means that we have symmetry and we can select. Ok,
05:06
I'm going to use all two and three to try to take a look at
05:09
a smooth display and you'll notice that it doesn't give us a smooth display.
05:12
There is a potential problem here because of the single point of contact.
05:16
What we need to do is we need to carry those four edges across,
05:20
which means that we have to do a little bit of manual work.
05:22
So we'll go to modify insert point will come from this point here
05:27
we'll go down to the middle of this edge and we'll hit enter.
05:31
Once you've created that we can select this.
05:33
Offending edge and hit delete on the keyboard.
05:36
This essentially creates a four sided patch but we
05:39
still have to connect these corners as well.
05:42
Let's go to insert point and will come from this corner down to the middle and say okay
05:48
now we can try to view this in smooth display and if it doesn't work
05:52
then the next step is going to be to try to use utilities and repair body
05:57
selecting the body and having it tried to repair any issues
06:01
by using the auto repair option.
06:04
And then we can say okay
06:07
when we take a look at this from the side it's still not producing a smooth display.
06:11
And part of the reason that we see that now is because of this face here.
06:15
This face is perfectly on the mid plane which means
06:19
that it's not going to be able to rectify it.
06:21
So what we're gonna do is we're going to select that face and hit delete
06:26
once we get rid of that face. Now we're able to see the rest of the saw
06:30
but we don't have the handle connected anymore.
06:34
The way that we need to approach this now that we have a body on both sides
06:38
is for us to get rid of some geometry or to use bridge to combine them together.
06:43
If we use bridge, we can select the bridge tool
06:47
and we can go from this face to this face.
06:51
Now you'll notice that it might produce a problem because of symmetry.
06:55
So you might need to select the faces across the symmetry in order to get this to work.
07:00
Once we do that, I'm going to reduce the number of faces between down to one and say,
07:05
okay,
07:06
you can see that it was able to connect those but these bottom faces,
07:09
I'm going to select and delete leaving them open on the bottom.
07:12
We never did finish off the bottom and that's okay because in
07:15
this video we're only exploring the concept of creating these foreign bodies.
07:20
Now that we've connected these together,
07:22
we can see some issues that are being presented.
07:24
The star points any time we have a transition or a change in direction.
07:29
This is where we have three or five
07:31
edges coming together instead of the traditional four.
07:34
This happens in these bottom two corners and appear
07:38
in order to make sure that this doesn't produce an issue.
07:41
Generally what we do is we add additional edges and we
07:44
move the star point further away from a change in curvature.
07:48
So in this case, what I'm going to do is I'm going to insert an edge
07:53
and then I'm going to go into my box display mode and begin manipulating the shape.
07:58
I'm going to double click on this inside edge.
07:60
Use modify edit form and scale it down slightly.
08:03
Then I'll select this inside vertex and I'll pull this up slightly as well.
08:08
Then I'm going to take this outside vertex and I'm going to pull it down slightly
08:12
to view this in smooth display.
08:14
And what we've done is we've taken the start point and we've moved it one edge away.
08:19
We can do the same thing on the bottom by either
08:21
extruding that down or going to modify an insert edge,
08:26
inserting an edge means that the star point is
08:28
no longer located directly on the transition of curvature.
08:32
This takes a bit of work and it takes some time and
08:34
you can see here we still don't have a perfect result.
08:37
It will take a little bit more work to fix.
08:39
So make sure that you play around with these options inserting and removing edges.
08:43
To see if you can get to a situation
08:45
where you no longer have star points causing problems.
08:49
Another thing that we can do is we can insert edge and
08:52
we can use the exact option and exact will make sure that
08:55
we maintain the same shape and it'll insert as many edges or
08:59
versaces as it needs to in order to maintain that shape.
09:03
So in this case we would need to do a little bit more
09:05
rita apologizing in order to move that star point a bit further away
09:09
but we already have a better result
09:13
from here.
09:13
The next thing that we want to talk about is
09:15
some additional tools in the use of flattening and thickening.
09:19
So I'm going to use undo to get rid of that last subdivision and I'm
09:24
going to go to modify and I'm going to look for the flattened tool.
09:27
A flattened tool will allow us to select versus is in this case,
09:32
I'm going to select the vertex is across the bottom here.
09:35
And what it's going to do is it's going
09:37
to average their position relative to each other,
09:40
flattening them out.
09:41
Note that we can do this with control points with
09:44
surface points when we're looking at in smooth display.
09:47
These will be surface points and we can also
09:50
select a specific plane or a parallel plane fit.
09:54
Will allow it to average the position between all of those.
09:56
So we're going to say, okay,
09:58
what we've done is we've taken those vortices
09:60
and we've averaged their position to flatten them.
10:03
The next thing that we want to do is turn this into a solid body.
10:06
This can be done after finishing the form and
10:09
taking the surface in the design work space and
10:11
converting it to a solid or we can create
10:14
a thickened version of it here using modify thicken.
10:19
Now there are pros and cons to each method.
10:21
When we use thick in here in the form workspace,
10:24
we have some control over the thick and type.
10:26
We can have a soft edge,
10:28
a sharp edge or no edge which will allow us to just create an offset version of this.
10:32
We can also determine whether it's normal or relative to an axis.
10:37
In most cases we're going to want to use the normal option.
10:40
I'm going to give this a two millimeter thickness and say okay,
10:46
the benefit to doing this in the forms workspace
10:48
is now we have direct control over the versaces,
10:51
edges and faces on both the inside and the outside.
10:55
This allows us to add or reduce the thickness in certain areas if needed.
10:60
Now that we've explored creating a form body,
11:02
the next thing for us to do is to turn this back into a solid body for the design.
11:07
When we select finish form fusion 360 will automatically convert the form body
11:12
into a solid body if it was closed or a surface body. If it was open.
11:17
If there are any issues with the conversion,
11:19
you'll be prompted to address the problem
11:21
inside of the forms contextual environment.
11:23
But at this stage now we have a complete solid body that we can add solid features too.
11:29
An opening for the trigger.
11:31
We can add vents in the side or we can
11:33
go back into the form and continue to manipulate it
11:37
at any point in time.
11:38
We can simply finish the form as it is a feature
11:41
in the timeline and continue to work with the solid body
11:45
for this example, we're pretty much done.
11:47
But let's go ahead and bring back our trigger model and the internal mechanics and
11:51
you can see that there are some clearance issues that would need to be addressed.
11:55
This is a great model to play around with and I
11:57
suggest that you continue to play around with the form body,
11:59
learning how to use some of the tools,
12:01
keeping in mind that you should save the thicken operation till
12:04
the very end as it becomes a bit more complicated to manipulate
12:08
at this point, let's go ahead and make sure we save the design before moving on.
00:02
refine and complete a form body.
00:06
After completing this video, you'll be able to use flatten mirror and thicken
00:12
Infusion 3 60.
00:13
Let's carry on with our trigger with
00:14
mechanics design at this point we've created the
00:17
basis for a form body and we're not going to do the entire form body.
00:21
But we do want to talk about a few more aspects of it.
00:24
The first thing that we want to talk about is how to add intricate detail.
00:28
As I mentioned,
00:29
we want to use the least number of
00:31
faces possible when we're working with foreign bodies
00:34
but there comes a time when we need to add specific detail.
00:38
That requires us to add more edges or faces.
00:41
For example, on this edge, if we want to add a crease,
00:44
we can double click this edge and we can use
00:46
the option to insert edge or even add a crease.
00:50
Now there are a couple of things that we should keep in mind
00:53
creasing an edge.
00:54
Or using something like beveling and edge will add additional
00:57
edges or maintain a hard edge between adjacent faces.
01:03
If we want to control this in a smoother manner,
01:05
it requires a little bit more hands on
01:07
approach and precision using something like insert edge.
01:11
So let's take a look at using insert edge
01:14
and from this view we're going to bring these edges close together.
01:18
When we bring the edges close together.
01:20
What we're doing is we're creating a tighter transition between the shapes.
01:24
We can hide the canvas image for now.
01:27
So as you can see what we're doing
01:29
here is we're creating a tighter transition between
01:32
the two adjacent faces and this is because if we go into box display mode,
01:37
what we have here is we've got a single edge right next to another edge.
01:42
We can manipulate these to change the way that the curvature works.
01:45
For example, if we go to modify edit form,
01:48
we can pull this edge back just a little bit and this will
01:51
affect the way in which that crease or that sharpened edge behaves.
01:56
Let's go ahead and repeat this process up here.
01:59
I'm going to double click on this edge and I'm going to use insert edge
02:04
And again from my front view double clicking the mouse wheel to fit the screen.
02:08
We're going to pull these edges relatively close together.
02:11
Now there is no specific number that will work
02:15
because this is a percentage value between other edges.
02:18
So for example,
02:22
side because there's not as much distance between these two edges.
02:26
So in general I go between about 0.52 point one and that gives me a nice tight crease.
02:31
Also keep in mind when we do this,
02:34
what we're doing is we're using the simple insertion
02:36
mode because that allows fusion 3 60 the ability to
02:40
not only insert the edge but also adjust the topology underneath.
02:44
If we go to our box display mode using Alton one,
02:47
we can make adjustments to this by scaling this
02:49
edge up and down or moving things around.
02:52
If you decide that you don't want that crease there,
02:54
it's as simple as selecting the edge and using delete on the keyboard to get rid of it.
02:58
So in this case we can maintain that smooth transition.
03:03
If we want to manually fade the crease away, this has to be done in a different manner.
03:08
For example,
03:10
we're going to select this bottom edge here and we're going to shift double
03:13
click up to here and we'll use modify insert edge Infusion 3 60 we can
03:19
create what's called a T point and this is an instance where the end
03:23
of one edge will end in the middle of another creating this T point.
03:28
Now that's perfectly okay.
03:29
But what we want to do is we want to tighten that crease up as we get further forward.
03:33
So in order to do this, I'm going to select these two edges.
03:37
Select insert edge and we're gonna put these two closer together.
03:42
Then we're going to use modify insert point and connect the two open edges.
03:49
Now, when we take a look at this using control and the number four to hide my edges,
03:53
you can see that the transition is still there but
03:56
we can control how close or how narrow it gets.
03:59
So this allows us to have a nice transition on the handle and then have
04:03
it blend away or tighten up as we get to the top of the device.
04:07
Going to use control and the number six to bring my edges back.
04:10
And you can also go to your display settings,
04:12
visual style and use shaded with visible edges only or shaded to remove the edges.
04:19
Now that we've explored ways in which we can add some additional detail.
04:22
Let's talk about mirroring this to the other
04:24
side and creating a thickened version of it.
04:27
So first we're going to go to symmetry and take a look at mirror internal.
04:31
And mirror duplicate when we create a duplicate body.
04:35
It'll create it across a plane or a selected reference when we use mirror internal.
04:40
It'll take a body that is already across that plane and it'll make it symmetric.
04:45
So in this case we're going to say mirror duplicate
04:49
and we want to select our mirror plane.
04:52
Notice here that there is a weld option
04:54
and there is a well tolerance.
04:56
What we want to see here is this green symmetry edge that happens between the bodies.
05:02
This means that we have symmetry and we can select. Ok,
05:06
I'm going to use all two and three to try to take a look at
05:09
a smooth display and you'll notice that it doesn't give us a smooth display.
05:12
There is a potential problem here because of the single point of contact.
05:16
What we need to do is we need to carry those four edges across,
05:20
which means that we have to do a little bit of manual work.
05:22
So we'll go to modify insert point will come from this point here
05:27
we'll go down to the middle of this edge and we'll hit enter.
05:31
Once you've created that we can select this.
05:33
Offending edge and hit delete on the keyboard.
05:36
This essentially creates a four sided patch but we
05:39
still have to connect these corners as well.
05:42
Let's go to insert point and will come from this corner down to the middle and say okay
05:48
now we can try to view this in smooth display and if it doesn't work
05:52
then the next step is going to be to try to use utilities and repair body
05:57
selecting the body and having it tried to repair any issues
06:01
by using the auto repair option.
06:04
And then we can say okay
06:07
when we take a look at this from the side it's still not producing a smooth display.
06:11
And part of the reason that we see that now is because of this face here.
06:15
This face is perfectly on the mid plane which means
06:19
that it's not going to be able to rectify it.
06:21
So what we're gonna do is we're going to select that face and hit delete
06:26
once we get rid of that face. Now we're able to see the rest of the saw
06:30
but we don't have the handle connected anymore.
06:34
The way that we need to approach this now that we have a body on both sides
06:38
is for us to get rid of some geometry or to use bridge to combine them together.
06:43
If we use bridge, we can select the bridge tool
06:47
and we can go from this face to this face.
06:51
Now you'll notice that it might produce a problem because of symmetry.
06:55
So you might need to select the faces across the symmetry in order to get this to work.
07:00
Once we do that, I'm going to reduce the number of faces between down to one and say,
07:05
okay,
07:06
you can see that it was able to connect those but these bottom faces,
07:09
I'm going to select and delete leaving them open on the bottom.
07:12
We never did finish off the bottom and that's okay because in
07:15
this video we're only exploring the concept of creating these foreign bodies.
07:20
Now that we've connected these together,
07:22
we can see some issues that are being presented.
07:24
The star points any time we have a transition or a change in direction.
07:29
This is where we have three or five
07:31
edges coming together instead of the traditional four.
07:34
This happens in these bottom two corners and appear
07:38
in order to make sure that this doesn't produce an issue.
07:41
Generally what we do is we add additional edges and we
07:44
move the star point further away from a change in curvature.
07:48
So in this case, what I'm going to do is I'm going to insert an edge
07:53
and then I'm going to go into my box display mode and begin manipulating the shape.
07:58
I'm going to double click on this inside edge.
07:60
Use modify edit form and scale it down slightly.
08:03
Then I'll select this inside vertex and I'll pull this up slightly as well.
08:08
Then I'm going to take this outside vertex and I'm going to pull it down slightly
08:12
to view this in smooth display.
08:14
And what we've done is we've taken the start point and we've moved it one edge away.
08:19
We can do the same thing on the bottom by either
08:21
extruding that down or going to modify an insert edge,
08:26
inserting an edge means that the star point is
08:28
no longer located directly on the transition of curvature.
08:32
This takes a bit of work and it takes some time and
08:34
you can see here we still don't have a perfect result.
08:37
It will take a little bit more work to fix.
08:39
So make sure that you play around with these options inserting and removing edges.
08:43
To see if you can get to a situation
08:45
where you no longer have star points causing problems.
08:49
Another thing that we can do is we can insert edge and
08:52
we can use the exact option and exact will make sure that
08:55
we maintain the same shape and it'll insert as many edges or
08:59
versaces as it needs to in order to maintain that shape.
09:03
So in this case we would need to do a little bit more
09:05
rita apologizing in order to move that star point a bit further away
09:09
but we already have a better result
09:13
from here.
09:13
The next thing that we want to talk about is
09:15
some additional tools in the use of flattening and thickening.
09:19
So I'm going to use undo to get rid of that last subdivision and I'm
09:24
going to go to modify and I'm going to look for the flattened tool.
09:27
A flattened tool will allow us to select versus is in this case,
09:32
I'm going to select the vertex is across the bottom here.
09:35
And what it's going to do is it's going
09:37
to average their position relative to each other,
09:40
flattening them out.
09:41
Note that we can do this with control points with
09:44
surface points when we're looking at in smooth display.
09:47
These will be surface points and we can also
09:50
select a specific plane or a parallel plane fit.
09:54
Will allow it to average the position between all of those.
09:56
So we're going to say, okay,
09:58
what we've done is we've taken those vortices
09:60
and we've averaged their position to flatten them.
10:03
The next thing that we want to do is turn this into a solid body.
10:06
This can be done after finishing the form and
10:09
taking the surface in the design work space and
10:11
converting it to a solid or we can create
10:14
a thickened version of it here using modify thicken.
10:19
Now there are pros and cons to each method.
10:21
When we use thick in here in the form workspace,
10:24
we have some control over the thick and type.
10:26
We can have a soft edge,
10:28
a sharp edge or no edge which will allow us to just create an offset version of this.
10:32
We can also determine whether it's normal or relative to an axis.
10:37
In most cases we're going to want to use the normal option.
10:40
I'm going to give this a two millimeter thickness and say okay,
10:46
the benefit to doing this in the forms workspace
10:48
is now we have direct control over the versaces,
10:51
edges and faces on both the inside and the outside.
10:55
This allows us to add or reduce the thickness in certain areas if needed.
10:60
Now that we've explored creating a form body,
11:02
the next thing for us to do is to turn this back into a solid body for the design.
11:07
When we select finish form fusion 360 will automatically convert the form body
11:12
into a solid body if it was closed or a surface body. If it was open.
11:17
If there are any issues with the conversion,
11:19
you'll be prompted to address the problem
11:21
inside of the forms contextual environment.
11:23
But at this stage now we have a complete solid body that we can add solid features too.
11:29
An opening for the trigger.
11:31
We can add vents in the side or we can
11:33
go back into the form and continue to manipulate it
11:37
at any point in time.
11:38
We can simply finish the form as it is a feature
11:41
in the timeline and continue to work with the solid body
11:45
for this example, we're pretty much done.
11:47
But let's go ahead and bring back our trigger model and the internal mechanics and
11:51
you can see that there are some clearance issues that would need to be addressed.
11:55
This is a great model to play around with and I
11:57
suggest that you continue to play around with the form body,
11:59
learning how to use some of the tools,
12:01
keeping in mind that you should save the thicken operation till
12:04
the very end as it becomes a bit more complicated to manipulate
12:08
at this point, let's go ahead and make sure we save the design before moving on.
