The architect is using MicroStation for design, the structural engineer is
using Revit Structure, the civil engineer is using AutoCAD Civil 3D, and
the engineer is using Plant Design Management System (PDMS) to
design a manufacturing plant. Does this sound like an unlikely
scenario? No, this is a real-world example. How we as building services
designers and engineers cope with and plan for this type of project will
ultimately affect the project's outcome and profit.
2D Data for Standard Details
When importing 2D data for standard details, you may well be linking
existing details from your company library. If you are using the same
drafting standards in AutoCAD and Revit, this process is relatively easy.
However, you might want to take a look at your existing company standards
if you are planning on running two systems.
One of the important consideration points relates to the use of the legacy
default AutoCAD SHX fonts, such as romans.shx or isocp.shx . The
great thing about these fonts for AutoCAD users is that you can control
the line weight of the text by utilizing different colors. However, although
Revitdisplaysthesefonts,theirappearanceisgovernedbythe SHXFontMap
file, which can substitute a TrueType font; you cannot adequately control
the line weight of text objects in Revit. In fact, the only way to edit the
weight of the text is to make it bold. Again, this process involves editing
the AutoCAD drawing. For example, Revit does not recognize all the codes
CAD users have used for years, such as the degrees symbol ( %%d ), underline
( %%u ), and so on. In this respect, the developers of Revit felt that focusing
on more-modern font technologies (TrueType fonts) was more appropriate
in the long run than using the much older SHX font approach. Therefore,
insteadofusinglineweight,Revitfavorsatextoutputthatisconsistentwith
most other word processing software.
Thus, in order to use Revit and AutoCAD and have your output identical,
you need to change your AutoCAD fonts to TrueType fonts. This has been a
hot topic for many people implementing Revit. Once you get past the shock
