3ds Max and Revit Interoperability - Part 05 - Adding and Removing Details

In this tutorial, you work on the curtain wall types to optimize the geometry for better transfer to 3ds Max.

Notes

  • Recorded in: 3ds Max 2015
  • This tutorial is intended for use with 3ds Max version 2015 or higher.

Transcript

00:00:06 --> 00:00:12
In the last movie, you started cleaning up the Revit model in anticipation of exporting it to 3ds Max.

00:00:13 --> 00:00:18
Another part of the process is adding and removing detail where needed.

00:00:18 --> 00:00:24
Sometimes it's easy to pinpoint the problem, other times, they only become apparent once you're in 3ds Max.

00:00:25 --> 00:00:33
Continue working on your Revit project or you use the file 02-Museum_curtainwalls.rvt if you need to catch up.

00:00:34 --> 00:00:37
This project has two types of curtain walls.

00:00:38 --> 00:00:47
One is made of clear glass, the other seems semi-transparent in Revit (made of frosted glass), but we'll make it opaque in 3ds Max.

00:00:47 --> 00:00:52
However, the material is not the concern right now. We're mostly interested in the geometry.

00:00:53 --> 00:00:57
It looks fine in Revit but let's take a look at it in 3ds Max.

00:00:58 --> 00:01:05
In the last movie, you created an .fbx file that you named mycurtainwalls.fbx that you're ready to link to 3ds Max.

00:01:05 --> 00:01:15
If you didn't have Revit and weren't able to create the fbx file, you can use the one provided to you (02-Museum_curtainwalls.fbx)

00:01:15 --> 00:01:24
In 3ds Max or 3ds Max Design, make sure your System Units are set to Feet as discussed at the beginning of this tutorial.

00:01:25 --> 00:01:30
Also set the Display to Feet w/ Fractional Inches to match the Revit display.

00:01:31 --> 00:01:35
You can set it to metric if you're more comfortable. Display Units are quite forgiving.

00:01:36 --> 00:01:41
Use Import > Link FBX to link the museum fbx file.

00:01:43 --> 00:01:48
Use the Combine by Family Type option for this example and attach the file.

00:01:48 --> 00:01:55
You will be prompted for a Daylight System;answer Yes for now, it'll be some time yet before we worry about rendering.

00:01:55 --> 00:02:03
If you're using 3ds Max or 3ds Max Design 2015, you will probably need to relocate or re-dock the Scene Explorer.

00:02:04 --> 00:02:07
Dismiss or move away the Links dialog.

00:02:07 --> 00:02:11
Zoom in on the building and take a closer look at the curtain walls.

00:02:11 --> 00:02:18
The curtain wall on the lower levels is made of clear glass and the panels are there to show it.

00:02:18 --> 00:02:22
However, there are currently no mullions separating the glass panels.

00:02:23 --> 00:02:30
Although you usually want to limit the number of polygons in a 3D scene, you still want to have important detail where you need it.

00:02:30 --> 00:02:35
Mullions are important and you need to see them if and when the camera gets closer to the wall.

00:02:36 --> 00:02:43
On the other hand, we want opaque panels on the upper level of the curtain wall, perhaps with a hint of a grout between them.

00:02:44 --> 00:02:49
Usually, such a grout can easily be simulated with a bump map in 3ds Max.

00:02:49 --> 00:02:56
Currently, even though the "upper curtain wall" is a single object, it is still made of a multitude of polygons.

00:02:57 --> 00:03:01
So, where you need to add detail to the lower curtain wall in the form of mullions,

00:03:02 --> 00:03:06
you need to remove detail from the upper curtain wall to simplify the geometry.

00:03:07 --> 00:03:10
You will rely on materials to simulate the tiling effect.

00:03:11 --> 00:03:15
So go back to Revit to make the necessary changes:

00:03:15 --> 00:03:19
Start with the grid lines you need to remove on the "blue" curtain walls.

00:03:20 --> 00:03:25
Select a blue wall section, it is defined as Curtain Wall - 10'

00:03:26 --> 00:03:32
You can directly edit this family type or make a copy if you plan to revisit it later.

00:03:32 --> 00:03:41
Click the Edit Type button and duplicate the type. Name the Duplicate: Curtain Wall - NO GRIDLINES

00:03:41 --> 00:03:47
Set the Vertical and Horizontal Grid Layouts to None, to prevent the creation of grid lines.

00:03:47 --> 00:03:56
Click OK to exit. You get a caution reminding you to completely delete the gridlines from this family type. Accept the recommendation.

00:03:56 --> 00:04:02
The grid lines have disappeared but the glazing seems to have reverted to clear glass.

00:04:02 --> 00:04:06
Click an empty area to make sure all objects are deselected.

00:04:07 --> 00:04:16
Hover over the curtain wall section you worked on and press Tab until only the perimeter gets highlighted, then click the mouse button.

00:04:16 --> 00:04:19
This selects the glass part of the curtain wall assembly.

00:04:20 --> 00:04:24
Switch the glazing again from Clear to Frosted.

00:04:27 --> 00:04:30
Repeat on the opposite side and at the front of building.

00:04:31 --> 00:04:38
At this point, you could take a moment and edit the frosted glass material if you're comfortable with Revit.

00:04:38 --> 00:04:42
If you're more comfortable with 3ds Max, you can also edit the material there.

00:04:43 --> 00:04:48
I will choose the second option in this tutorial, simply to emphasize that both methods are valid.

00:04:49 --> 00:04:54
So, leave the frosted glass material for now and concentrate on the mullion creation process.

00:04:55 --> 00:05:00
To start with, I would suggest making the clear glass curtain walls more consistent.

00:05:00 --> 00:05:08
The roof sections seem to be based on 10-foot spacing. We'll switch them to 6-foot spacing, as in the lower levels.

00:05:24 --> 00:05:28
Since we're at it, let's add a few door openings as well.

00:05:29 --> 00:05:34
For that, go to the Architecture tab and chose Curtain Grid.

00:05:35 --> 00:05:40
By default, it is set to work across all segments, this is fine for now.

00:05:40 --> 00:05:43
Set a grid line to be 7-feet high.

00:05:48 --> 00:05:50
Repeat on all other roof walls.

00:06:01 --> 00:06:06
Click the Modify button to exit the command, and click an empty area to deselect all objects.

00:06:07 --> 00:06:13
Hover and use the Tab key to select the panels where you want to have doors.

00:06:16 --> 00:06:20
Switch the panel type to use the Store Front Double Door system.

00:06:21 --> 00:06:23
Repeat where needed.

00:06:31 --> 00:06:36
To create mullions out of grid lines, first you need to have a mullion type defined.

00:06:37 --> 00:06:41
Expand the scene browser and the Curtain Wall Mullions category.

00:06:41 --> 00:06:47
You'll use a simple rectangular type. Right-click Rectangular Mullion and choose New Type.

00:06:48 --> 00:06:54
Name it 2x4. Once you've named it, right-click to edit its properties.

00:06:55 --> 00:07:01
Set the thickness (or depth) to 4". Notice that you have two width values.

00:07:02 --> 00:07:06
The sum of both values must equal the overall length you want to have.

00:07:07 --> 00:07:14
Here, we need a 2" width so you can set the values to 1" on each side of a center line.

00:07:15 --> 00:07:19
For a material, you can create a new one or use an existing one.

00:07:19 --> 00:07:24
In this case, you can simply use the Railing - Polished material.

00:07:25 --> 00:07:30
Once you have defined a mullion type, you can use it to replace grid lines on Curtain Walls.

00:07:31 --> 00:07:35
This is done by going to the Architecture tab and clicking the Mullion button.

00:07:36 --> 00:07:41
You then select a mullion type, in this case the one you just created and named 2x4.

00:07:42 --> 00:07:45
You can then choose to replace a grid line,

00:07:47 --> 00:07:49
a grid segment,

00:07:53 --> 00:07:57
or all grid lines on a curtain wall section.

00:08:05 --> 00:08:12
Save your file when you're done. More importantly, you need to update the fbx file you already linked to 3ds Max.

00:08:13 --> 00:08:20
Use the Export to FBX feature to overwrite the file you created earlier and that you named mycurtainwalls.fbx

00:08:23 --> 00:08:27
Go back to 3ds Max. Your scene has not updated yet.

00:08:27 --> 00:08:32
Use References > Manage Links to access the Links dialog again.

00:08:33 --> 00:08:38
Go to the Files tab and notice the red flag, indicating the FBX file has changed.

00:08:39 --> 00:08:42
Click the Reload button, a Settings dialog appears.

00:08:43 --> 00:08:46
Arguably the most important options here relate to Materials.

00:08:47 --> 00:08:55
My advice is to always retain 3ds Max material adjustments on reload, so that any material tweaking in 3ds Max is not lost.

00:08:56 --> 00:09:00
Once the file is reloaded, you should notice significant differences.

00:09:01 --> 00:09:08
The redundant opaque panels are gone and now you have additional geometry in the form of mullions and doors.

00:09:09 --> 00:09:13
In the next movie, you'll take a look at stairs and railings.
