The issue you face here is whether the “intelligent” data in the AutoCAD
file is important or, for the sake of the Revit project, can you explode (if
possible) the objects to base elements that can be read in Revit?
You have other options if the data has been created in one of the vertical
products. You'll learn about these options in the section “3D Data Types”
later in this chapter.
MicroStation 2D DGN
Revit currently supports AutoCAD versions 2000 through 2015, and most
MicroStation versions can be imported. The possible alternatives here
include asking the originator to use their version of the Save As command to
create an AutoCAD file format that MicroStation can handle, use a specially
developed app to export to IFC, or export as a DXF file.
DXF
The Drawing Exchange Format (DXF) has been around for almost as long
as DWG and DGN. It is a well-recognized and trusted translation medium
between primarily 2D formats. The DXF file format also supports
conversionstofileformats2000-2010, althoughcareshouldbetakenwhen
using this format because it is generally regarded as offering the most basic
compatibility with the likelihood of the worst fidelity.
