Underlays
BricsCAD does not load or display DGN and DWF underlays. It does, however, attach PDF
and raster image underlays, as well as externally-referenced drawing (xrefs) files.
Viewports
BricsCAD creates and clips rectangular and polygonal viewports, but cannot invert viewports
clipped by the VpClip command.
Visual Styles
BricsCAD reads, edits, and creates visual styles, but cannot apply all of the properties that
AutoCAD can. For instance, the properties of Intersection Edges are not yet implemented. On
the plus side, BricsCAD provides a longer list of default visual styles than does AutoCAD. See
the complete list in the “Compatibility between Styles” section near the end of this chapter.
MISCELLANEOUS COMPATIBILITY ISSUES
There are aspects of CAD programs that are unaffected by DWG compatibility, yet are important
to the end user . For example, I find the ribbon layout in AutoCAD overwhelming
(in the negative sense), and the default white text on black background difficult to read.
Other non-DWG issues include the following items:
