Using Structural Desktop

Frequently Asked Questions
Question What are the requirements to run Structural Desktop
Structural Desktop needs a PC with Windows 95/98, Nt40 sp6a, 2000 Pro, XP home or XP Pro. Structural Desktop also requires AutoCAD or ADT from AutoDesk. Versions of AutoCAD supported are 2000, 2000i, 2002, 2004, 2005, 2006, 2007, 2008, and 2009. ADT Versions 3.x - 2009 are also supported. AutoCAD LT WILL NOT WORK.
Question What analytical programs does Structural Desktop work with?
Structural Desktop bridges the gap between your analysis file and your finished drawings. It can read GT STRUDL, RISA 3D, and STAAD.Pro files.
Question What is an "Application Load" program?
Structural Desktop is an “Application Load” program, meaning that it is made to run inside AutoCAD and other AutoDesk programs. Structural Desktop is not a stand alone program. It is imperative that the installation instructions for Structural Desktop be followed exactly.
Question What is the difference between a *.DFX and a *.HLD file?
A DXF file contains only AutoCAD lines. They know where they are in space, but they have no data associated with them. A DXF file of a 3-D model is a centroidal line model. A HLD or Hold file contains Structural Desktop members and elements as well as any AutoCAD information such as preferences and layer settings. These are intelligent objects that not only know where they are but what they are. The model can viewed in centroidal line, envelope, or solid mode.
Question What data is shared between SDT and the analytical program?
Structural Desktop reads and writes:
  • joint coordinates
  • member and element incidences
  • member and element properties
  • units
  • constants
  • beta angles
