tips on Importing CaD Files
to minimize the adverse impact of unnecessary styles and types carried into the revit environ-
ment with exploding imported CaD data, we recommend removing extraneous data in the CaD
ile
before
importing it. Here are some general tips for this workflow:
◆
If your import contains elements such as hatches or annotations not intended for use in the
revit project, delete them before importing.
◆
Consider consolidating data within the CaD file to a minimum number of layers or levels. Doing
so will ease the process of converting to revit line styles if the file is exploded. This process
will also facilitate graphic overrides.
◆
If it is allowable within your workflow for the imported CaD file, import it into a family, and
then insert that family into your project. This will not reduce the overall file size, but it will
make it a lot easier to find and manipulate should your imported CaD file need additional
changes. It will also give you some extra control over the graphic display of the imported file.
revit software doesn't allow line segments shorter than 1/32˝ (0.8 mm). While it might seem like
you wouldn't have a lot of lines that length, many manufacturers' details contain small fillets in
sections and plans and will fall into this range. take care when exploding CaD details with very
small line segments because they will be removed upon exploding. a good example of this is the
manufacturers' details. Many of those CaD files have the level of detail needed to create the part
(for example, a window mullion) but are not necessary for architectural detailing. revit will auto-
matically remove those shorter segments, and in some cases it might be quicker to simply trace
over the detail rather than insert and explode it.
