In FlexTABS, the PIPE3 tab has 3D ON and 3D OFF buttons which turn on and off the 3D-functionality of the product. In order to turn on and off the 3D-graphics but continue working in 3D-functionality, the TURN OFF 3D LAYERS and TURN ON 3D LAYERS buttons should be used; also found on the same PIPE3 tab.

This problems derives from erroring out of a previous command. To fix this, type UCS [enter] DEL [enter] * [enter].

The machine that is viewing the drawing needs to have the three SHX files; IDSSIM.SHX, IDSTXT.SHX, and IDSCOM.SHX copied to C:\Program Files\AutoCAD 200x\Fonts folder. These SHX files can be found in any of the FlexCAD product folders (i.e. C:\Idswin\ISO, C:\Idswin\FLO, etc).

Type CONFIG on the command line and hit enter. On the System tab, the check-box option for 'Load acad.lsp with every drawing' needs to be checked . After this is done, re-open the drawing.
