Suitability of Imported Geometry
When you import a file into Revit Architecture, the format of the imported file may support varying qualities
of geometry. These variations are caused by the file type, the export settings, and the import settings.
Some tools and capabilities in Revit Architecture require specific types of geometry. For example:
■
The Join Geometry tool requires volumetric geometry.
■
Rendering an image requires that faces are associated with material properties.
■
The Roof by Face tool requires geometry with suitably sized faces for flat roof panels or a NURB
representation of a complex, shaped roof panel.
■
Masses require volumetric geometry to calculate volume, surface area, and floor area faces. See
Considerations for Imported Geometry in Mass or Generic Model Families
on page 626 and
Massing Studies from Other Applications
on page 626.
You can import many different types of file formats into Revit Architecture. When you export a file from
the originating application for use with Revit Architecture, you can set a variety of export options. With
these many variations of file formats and export options, it is important to ensure that the exported file
provides the geometric data needed for the Revit capability that you plan to use. To optimize results with
various file formats, consult the documentation provided with the exporting applications.
Importing or Linking CAD Formats
Open a Revit project, and click Insert tab
➤
Link panel
➤
Link CAD, or Insert tab
➤
Import panel
➤
Import
CAD to import or link vector data from other CAD programs such as AutoCAD (DWG and DXF), MicroStation
®
(DGN), SketchUp (SKP and DWG), and ACIS (SAT). Revit Architecture supports importing most DGN surfaces
and solids with the exceptions of cones, B-Spline surfaces, and SmartSolids.
In addition to using the Import CAD and Link CAD tools, you can import CAD files using drag-and-drop
from Windows
®
Explorer onto a model, drafting, or sheet view of Revit Architecture. See
on page 1389.
You can mirror imported and linked CAD files. See
on page 380.
NOTE
Revit Architecture imports ACIS solids from SAT files. SAT file formats later than version 7.0 do not import
into Revit Architecture. You should determine which version your solid modeling program is creating. Some solid
modeling products (such as form-Z
®
) create SAT file formats later than version 7.0 by default.
Snapping to Imported Geometry
Suppose that you import an AutoCAD
®
drawing into Revit Architecture and then want to trace over walls
in that drawing. As you place the cursor near the lines representing the walls, it can snap to the lines or the
midpoint between the lines.
Proxy Graphics from AutoCAD Files
Revit Architecture supports reading in proxy graphics from AutoCAD files. Proxy graphics are AutoCAD's
representations of AutoCAD Architecture objects. Unlike AutoCAD Architecture objects, proxy graphics have
no intelligence.
Proxy graphics can exist for many types of data in AutoCAD, including Mechanical Desktop (MDT) parts
and AutoCAD Runtime eXtension (ARX) objects. If you set the Proxygraphics command to 1 in AutoCAD,
Revit Architecture can then import ARX objects and AutoCAD Architecture objects (such as walls and floors)
in the DWG or DXF file.
