Create custom bridge parts using Inventor and Revit, add these parts to a bridge model in InfraWorks, and perform simple rebar modeling and scheduling in Revit.
Transcript
00:03
We're going to be looking at creating custom
00:05
bridge parts and also some rebar detailing.
00:10
So we're going to begin by looking at how we can create a
00:13
bridge part using inventor.
00:16
So we need to start with a sketch of the peer profile and we do this in the XZ plane
00:22
and then simply trace the outline of the peer profile with the line tool.
00:26
We can do this freehand just by making sure that we are pointing
00:30
in the right direction and then entering a valley for the distance.
00:34
In this example,
00:35
we're going to use the mirror tool to
00:37
replicate the opposite side of the pier outline.
00:40
As far as dimensioning of the profile goes,
00:43
we are provided with some standard mentions,
00:46
but we will need to make changes to those and add some very specific
00:49
ones in order for this peer to work when it gets to info works.
00:55
So each category of part
00:57
that being abutments, peers foundations, et cetera
01:01
have a specific number of required parameters
01:05
which must be included in the model and must have the correct syntax. In order to work
01:10
these required parameters shown here in red
01:14
will be driven by Infra works,
01:16
the rest will be user driven and whatever is required to fully define the part.
01:20
In this case, uh appear,
01:25
we can make changes to existing dimensions by double clicking them
01:29
and changing the contents or add them using the dimensioning tools.
01:34
Always taking care to make sure that the syntax
01:37
is correct in the case of the required parameters.
01:40
And then just by adding
01:42
additional use dimensions to fully define the part
01:45
at this stage,
01:46
we also need to make sure that the part
01:48
will behave as expected when the dimensions change.
01:51
And this is taken care of by using constraints.
01:55
So as we were tracing the profile out
01:58
inventor was adding some constraints for us to make sure that lines
02:02
drawn at right angles for instance stay that way when dimensions change.
02:06
But on the mirrored side, there are some missing.
02:09
So we can add these using the constraint tools
02:12
to make sure everything stays as it should be
02:15
as the dimensions change.
02:17
When the part gets into infra works.
02:20
When the profile is completed,
02:22
we can close the sketch down and then use
02:24
the extrusion tools to actually create the part.
02:27
In
02:27
this case,
02:28
we will select a symmetrical extrusion to set
02:31
out the thickness from the center of the pier
02:34
and then label it with a parameter so that we
02:36
can adjust it when it gets into infra works.
02:39
All that is then left to do is to look at the parameter list.
02:42
And make sure that the parameters we need
02:44
are selected ready for export to Infra works
02:47
and then simply save the part
02:49
and it is ready for use.
02:52
Now, the other method of creating these parts is to use a rivet family.
02:57
So the first thing we need to do is to start
02:59
a new rit family and then just select a generate model
03:03
rev it will then present us with a number of views for us to start modeling in
03:07
the process of modeling. The part is different to the inventor method
03:11
in that we need to create a framework for the geometry first using reference planes.
03:18
So we just need to create a series of reference
03:20
planes that will replicate the critical dimensions of the part.
03:26
When that has all been arranged, we can then look at the actual dimensions.
03:34
So in this case, we will use an aligned dimension to identify the pier height.
03:40
If the dimension text is too small, we can adjust the scale
03:45
and then look to the labeling feature to
03:48
specify any parameter labels including our required parameters.
03:54
We need to continue this process until all the
03:56
necessary dimensions to adequately define the part are specified.
04:01
We can then use the extrusion tool to trace the actual geometry of the new part.
04:08
Once completed,
04:09
each part of the traced geometry needs to
04:11
be locked to the reference plane framework.
04:14
The easiest way to do this is by using the align tool
04:18
aligning each segment of the geometry to the corresponding reference plane,
04:22
making sure that in each case, the geometry is locked to the reference plane
04:33
at this point,
04:34
we can now stress test the part by adjusting some of the dimension values.
04:39
If the part has been modeled correctly,
04:41
then the part should behave as expected and change parametric
04:45
when the values are altered.
04:49
So when the extrusion is created, it is formed with a default thickness.
04:53
So we will need to change view and add some
04:56
reference planes there to define the thickness of the pier.
04:59
Always taking care to add some dimensions to
05:02
ensure that the central reference plane remains central.
05:06
But the process is essentially the same as we've carried out on the profile view.
05:12
Once that has been done
05:13
including the addition of a thickness parameter.
05:16
The pier is essentially complete and only needs saving in
05:19
order for it to be used in infra works.
05:21
So the process for adding either of the parts we've just created is identical.
05:26
For both inventor or reddit.
05:28
We add the part in the star palette as we do for all additional content,
05:33
we can configure the part for the parameters.
05:35
We want to allow the end user to see and change the labels if necessary.
05:40
Once the part is added to the star palette, it is then available for use.
05:44
All we need to do is select the pair we want to change in the model
05:48
and select our new peer from the resulting list,
05:51
the new pair will then be modeled in
05:53
place with the required parameters driving that geometry.
05:56
And then the end user making the necessary changes to the user parameters
06:01
to arrive at the required end geometry.
06:04
That pair can then be copied to other positions within the model.
06:07
And they will adapt parametric to the environment. They find themselves in
06:11
the bridge model can then be published ready for the
06:14
documentation phase that we have covered in our earlier video.
06:17
But it is important to point out that
06:19
rit generated parts,
06:21
maintain their family status and can be
06:23
adjusted within the rev it property palette.
06:31
So we are now going to turn our attention to some simple rebar modeling.
06:36
So the recommendation for this is to make sure
06:38
that our original rivet template was a structural one.
06:42
This will ensure that all the rebar,
06:43
visibility settings and rebar shapes are correct from the start.
06:48
Once the concrete cover settings have been adjusted,
06:50
we can then straight away select the rebar shape that
06:53
we require and place that bar in the section view,
06:56
the bar will snap to the concrete cover and size
06:59
itself accordingly and will position itself at the section location.
07:04
We can then use the edit constraints functionality to make
07:07
adjustments to the position and length of the bars.
07:10
Constraints can be relative to the concrete or another bar.
07:15
Clicking on a constraint allows the value to be adjusted to suit.
07:19
We can then use the rebar set drop downs to make
07:22
adjustments to the number of bars and how they are set out
07:26
as well as shape driven bar placement. There is also free form placement
07:30
that works in the 3D view.
07:32
This allows alignment for bar sets to be distributed within complex concrete
07:36
shapes or for bar shapes themselves to follow those complex shapes.
07:42
To use one of the free form methods.
07:45
We will need to select the concrete part in a 3d view
07:49
and then specify which free form method to use, either aligned or surface.
07:55
We will then need to specify the rebar set values
07:58
and then proceed to select the host face for the bars followed
08:02
by faces to specify the start and end of the bar set.
08:08
Once the bars have been placed,
08:10
they can then also be adjusted using the constraints mentioned earlier.
08:15
Using this combination of bar placement methods,
08:18
we can place the other required bar sets within
08:21
this power cap in both the longitudinal and transverse directions
08:25
managing the bar layering with constraints.
09:01
If the structural template has been used,
09:04
a rebar schedule will have been scheduling each bar as it is placed.
09:09
This schedule can be examined and modified using the schedule
09:12
properties to customize the schedule to the required specification.
09:17
Once the schedule has been formatted,
09:19
it can then be added to any sheet to form part of the documentation output.
00:03
We're going to be looking at creating custom
00:05
bridge parts and also some rebar detailing.
