When creating content in SketchUp for use in Revit Architecture, consider the following restrictions:
■ Exploding 3D data : In Revit Architecture, you will not be able to explode 3D data. If you try this, 3D
faces will disappear, and you will receive a warning message.
■ Parameters : In Revit Architecture, you cannot add parameters to control geometric flexing. However,
you can add some controls that manipulate imported data, such as the location of an imported element
and its material assignments.
■ Visibility/graphics : In Revit Architecture, you cannot manipulate the geometry or isolate parts of whole
elements with visibility/graphics settings.
■
Two-sided surfaces : If a material or color is assigned to only one side of a surface in SketchUp, Revit
Architecture applies the material or color to both sides of the surface by default. If there is material on
both sides of the surface, Revit Architecture applies the Face 1 material to both sides. If faces are flipped
and painted differently in SketchUp, they may not display the correct material in Revit Architecture.
■
SketchUp properties : The following SketchUp properties are currently not supported in Revit Architecture
import: Texture Image Maps, Transparency, “Smooth” Curved Surfaces, Text and Dimensions, Raster
Images, and saved “Pages”.
■ Cut planes : Imports cannot be cut by a cut plane unless imported into a cuttable family category. See
Cuttable Families on page 514.
■ SketchUp and massing : Not all SketchUp imports are appropriate to massing. See Suitability of Imported
Geometry on page 1387. Also see Importing Massing Studies from Other Applications on page 626.
■ Scaling : Groups or components that have been scaled in their entirety with the SketchUp Scaling tool
may be incorrectly scaled when imported to Revit Architecture. Exploded SketchUp models should import
at the correct scale.
Importing ACIS Objects
Revit Architecture supports the import of ACIS objects contained in DWG, DXF, and SAT files. (ACIS objects
describe solids or trimmed surfaces.) For example, you can create ACIS objects using the AutoCAD commands
Draw Solids and Draw Region. You can also import SmartSolids
™
from MicroStation
®
into Revit Architecture.
To import ACIS objects, use the procedure Importing or Linking CAD Files Using the Import CAD and Link
CAD Tools on page 1388.
Revit Architecture supports the following types of surfaces when importing ACIS objects:
■ Plane
■ Sphere
■ Torus
■
Cylinder
■ Cone
■ Elliptical cylinder
■ Elliptical cone
■ Extruded surface
■ Revolved surface
■ NURB surfaces
