Q - question

OSNAPZ for happier UserZ... (ignore Z)

A - answer The new system variable OSNAPZ in AutoCAD 2006+ can suppress object snapping to Z values (ignore object elevation) and use the current Elevation value instead.

You can also the setting "Replace Z value with current elevation" in the Options dialog.

Preset the OSNAPZ by adding:

(setvar "osnapz" 1)

to your ACADDOC.LSP file, or toggle the OSNAPZ status by adding a button with the menu macro:

^C^C(setvar 'osnapz (abs (1- (getvar 'osnapz))))

to your ribbon (CUI).

Z values captured from osnap can be source of many problems in drawings.
