What happened to my PLOT/FILE dialog box ?
You may occasionally find yourself in a situation where the NEW, OPEN, and SAVE commands do not provide a dialog. Simply enter FILEDIA at the command prompt and enter a value of 1. If you attempt to PLOT and fail to get a dialog, simply enter ` at the command prompt and enter a value of 1.
Using file dialog at prompts
Sometimes settings (such as FILEDIA) can cause certain routines to ask for a file name at the command prompt. In these cases you can enter the tilde ~ character followed by enter to bring up the file selection dialog.
Ignoring object snap elevations
A frequent problem in objects snaps is the inheritance of the Z value when snapping to a point. GstarCAD addresses this problem with OSNAPZ system variable. If set to 0, osnap uses the z-value of the snapped point. If set to 1, it uses the x+y of the snapped point and the current value of the ELEVATION system variable. Also note that when creating lightweight polylines, the elevation of the first snap will determine the elevation. After that, any snap to other elevations will be ignored.
