Here's a list of a few must know setvars

1) Missing dialog boxes use: FILEDIA - Set to (1)

2) Getting a prompt About to Regen - Proceed?: REGENAUTO - Set to ON

3) AutoCAD point display: PDMODE - This varies based on how you wish them to be displayed. Use DDPTYPE to change the display using a dialog box. We "use AutoCAD POINT for Marker" for our AECC_POINT objects. This allows us to control their display without changing the master dwg where the points are located.

4) Attribute display: ATTDISP Enter attribute visibility setting [Normal/ON/OFF]: - Set to Normal if they're not displaying, this is default. Set to ON to view invisible attributes. (Use ON to see LDT Profile tag in the lower left corner of your grid). I haven't found a reason for OFF.

5) Middle button to Pan or Osnap: MBUTTONPAN - Set to (0) for Osnaps or (1) for Pan.

6) Change your pick box size: PICKBOX - Set to desired size. Typically around (5).

7) Change your Cursor X,Y vector length: CURSORSIZE - Set to (100) for standard length. Set to a lower # for shorter vectors.
