DXF files are a file exchange format support by most CAD programs. Multiframe reads and writes 2D and 3D DXF files so that you can export Multiframe geometry to a CAD program or import a frame's geometry that you have drawn in a CAD program.

Joint Springs can be used to emulate soil support under a foundation.

You can stop analysis or rendering in Multiframe by pressing the ESC key.

A Type 32 error is caused when you try to open a file that is already open in another application. This error appears quite often when you have exported a DXF from AutoCAD using Save As... and then try to import the DXF into Multiframe. AutoCAD has marked the file as in use and will not let Multiframe open it. Close the file in AutoCAD and then import it into Multiframe.

Currently there is a problem when installing on Windows Server 2003. You may get an "Error 131. There is a problem with this Windows Inst...." message towards the end of the installation process.  To get around this problem you must install the InstallShield update manager and then install Multiframe again.
