use promote and demote, identify the end of part and end of assembly feature marker, modify consumed work features,
00:14
share a sketch and rearrange feature order.
00:18
Inside of Inventor, we want to open up two supplied datasets:
00:23
Engine Mark 2.iam, which can be found in the assembly subfolder under Engine Mark 2,
00:28
and the ShareSketch.ipt, which can be found in the top of our project.
00:33
We want to begin with the engine and we want to talk a little bit about the functionality of the browser.
00:38
The browser is listed here on the left-hand side.
00:40
And when we're dealing with assemblies, the browser is not looking at the history or the order of operations
00:46
as much as it is the components in an assembly.
00:49
But even though we have components in an assembly, there are still some functionalities that we want to identify.
00:55
First, we want to identify Promote and Demote.
00:58
If we have a couple of components, for example, the engine piston, the wrist pin, and the connecting rod,
01:04
we can select those components, right-click, go to Component and select Demote.
01:11
We can also use the shortcut key, TAB.
01:13
I'm going to give this a name, “RotatingAssembly”.
01:18
This is going to create a new subassembly and once we say OK, we'll select Yes to restructure.
01:26
This is going to create a new subassembly at the bottom called RotatingAssembly.
01:30
And underneath that rotating assembly, we can see that we've got the engine piston, the wrist pin, and the connecting rod.
01:37
It is important to note that when we create subassemblies by using Demote or undoing subassemblies by using Promote,
01:44
that joints, constraints, and assemble tools are going to be consumed within that subassembly.
01:51
In some instances, this does pose potential problems preventing your subassemblies from rotating properly.
01:57
You may need to select your subassembly and select Flexible to allow it to rotate.
02:02
Let's go ahead and go to our position representation, select Free and see if we can rotate this assembly.
02:09
We can see here by using the Free option and making our subassembly flexible,
02:15
we are able to now have a rotating assembly which contains the piston, the wrist pin, and the connecting rod.
02:21
If we wish to undo that, we can select our subassembly
02:24
once again, right-click and go to Component and you can see that we no longer have a Promote option.
02:30
In order to promote these components, we need to select the subcomponents in the assembly,
02:34
go to our Component reference and select Promote.
02:38
We're going to select Yes and Promote will allow us to remove that subassembly and put these components back at the top level.
02:45
Note that the rotating assembly subassembly is still in our design, however, it's now empty.
02:51
This means that we can select it and delete it if we wish.
02:54
In this case, we're going to delete it and remove it from our assembly.
02:58
The next thing that we want to discuss is the end of part marker and the end of assembly feature marker.
03:04
When we look at parts like ShareSketch, they have an end of part marker that allows us to drag it up inside of the browser
03:11
and we can temporarily suppress certain features and sketches in our design.
03:15
When we look at an assembly, the assembly does not have the same end of assembly marker
03:19
because the order of operations is not important in an assembly.
03:23
However, if we do begin to add assembly features from the 3D model tab,
03:27
for example, if we add a small fillet to the upper edge of this piston.
03:31
Let's set this to a small value such as .5 and say OK.
03:35
The fillet feature is time-dependent, which means it does need to have an end of feature marker.
03:41
This means that we can use the end of feature marker to roll back before and temporarily suppress that feature, or roll it to the end.
03:49
Assembly features are only going to apply at the assembly level and will not modify the original design.
03:55
If we find the piston, which is now located at the bottom of our assembly,
03:59
and we open the piston, the upper edge will not have that same fillet applied to it.
04:04
So keep in mind that using the end of part marker
04:07
is different than using an end of assembly feature marker, but they are very similar in nature.
04:11
Let's go ahead and select and delete the fillet and note that the end of feature marker disappears.
04:17
If we take a look at the ShareSketch part, this part contains a single extrusion feature.
04:23
If we expand it, it has a single sketch.
04:25
The single sketch needs to be used multiple times.
04:28
This means that we need to share the sketch.
04:30
One condition for sharing a sketch is that it must currently be consumed, and what that means is it needs to be used in a feature.
04:38
If we right-click on Sketch1 and select the option to Share Sketch, it'll place all shared sketches above the first feature.
04:45
This means now Sketch1 can be reused for additional features.
04:49
Let's go ahead and take a look at using it for an Extrude.
04:52
We want to extrude the holes through the part.
04:55
We're going to use through all and select OK.
04:58
Let's say that we decide to add additional features, for example, a fillet.
05:03
We can add a large fillet to this design, but it does have some implications on how the fillet and the edges are going to be divided.
05:10
For example, this small section is only here because the hole was added.
05:14
If instead we take that fillet feature and drag it up above the extrusion, you can see that the divisions of the faces on our body are different.
05:21
And that's simply because the extrusion feature was added after the fact and the way in which the faces are created is now different.
05:29
The order of operations and whether or not you share sketches is going to be an extremely important part of designing any single part
05:37
or subassembly inside of Inventor.
05:39
And it's also important to keep in mind that consumed features, such as sketches inside of an extrusion,
05:45
are not the only consumed items inside of an inventor part.
05:49
Let's go ahead and take a look at creating an axis.
05:51
When we select Axis, we can select holes and this will allow us to generate an axis.
05:57
We'll right-click and repeat the work axis and apply one here and apply one here.
06:02
If we want to generate a plane through those points, we can select an axis,
06:07
we can select a secondary axis, and this is going to generate a plane based on our selection.
06:12
Note inside of our browser that Work Axis1 has a shared icon.
06:18
This is because it was shared when creating an additional feature, in this case, Workplane1.
06:23
Work Axis1 and Work Access3 were both used in order to create Workplane1.
06:28
These are now considered consumed features.
06:31
We can also share these and reuse them as needed, but we can right-click on Workplane 1
06:36
and we can change the Consumed Input option to be deselected.
06:40
When we deselect the Consume Inputs option, this will place all of the features at the same level inside of our browser.
06:47
This could be helpful if you want to have a full view of all of the features, in this case, a work axis or a work plane,
06:53
inside of a design, but in most cases leaving them consumed is perfectly fine.
06:58
So in conclusion, it's important to remember that using the browser in a part or an assembly has different use cases and implications.
07:06
Working inside of a part, we have an end of part marker that allows us to determine where the end of the part is calculated.
07:12
This temporarily will suppress any features or work features like work planes that are after the end of part marker.
07:19
We can also reorder features by dragging them around in the browser, in this case, positioning a fillet before an extrusion.
07:26
We can share sketches that are consumed by right-clicking and selecting Share Sketch if we need to use them for additional features.
07:34
An assembly doesn't have an end of assembly marker,
07:37
but as soon as we begin adding assembly features, things like fillets and extrudes,
07:41
then we'll have an end of feature marker at the top of our assembly browser.
07:45
Subassemblies can be created and dissolved by using the Promote and Demote options in the right-click menu.
07:52
None of the things that we've done here need to be saved, so feel free to close the designs out and move on to the next video.
