Use the Revit Preset
3ds Max includes a preset named Revit that you can use when using File
Link to link a drawing that is exported from Revit. The Revit preset has many
of the following suggested settings turned on by default. Or, you can use the
Revit preset as a basis for your own customized Revit preset containing the
settings you prefer.
The Revit preset can be assigned from the Preset list on the Attach panel of
the
File Link Manager on page 6783 . You can edit the preset on page 6812 by
choosing the Revit preset shown on the Presets panel of the File link Manager.
If you plan on creating your own presets or modifying the Revit preset, use
these settings to streamline the file linking process.
Turn on Weld and set a Weld Threshold
Weld and Weld Threshold are found on the Basic panel of the File Link
Settings dialog or in the Geometry Options group of the AutoCAD
DWG/DXF Import Options dialog.
When Revit exports model geometry to a DWG file, objects are translated as
multiple surface meshes. For example, a single wall is made up of 6 or more
AutoCAD entities; each a polyface mesh with vertices that overlap their
neighbors. When the meshes get linked to 3ds Max, the File Link Manager or
DWG/DXF Importer recombines them back to a single object. However, when
the meshes are recombined, their vertices are not welded, so you end up with
a larger and less elegant model than expected. By turning on the Weld option
and setting an appropriate Weld Threshold (like 0.1" or smaller), coincident
vertices are welded together and the file structure is more efficient.
NOTE This is particularly important if you plan to do radiosity rendering because
gaps in the model can cause leaks that greatly increase the rendering time.
Turn on Views (cameras)
Views (cameras) is found in the Include group on the Basic panel of the
File Link Settings dialog and the AutoCAD DWG/DXF Import Options
dialog.
