JTB OsnapzBG Plus

With JTB OsnapzBG Plus loaded any change of the AutoCAD variable OSNAPZ will also change the drawing window colors depending on if OSNAPZ is set to 0 or 1.

OsnapzBG Plus has the ability to set any of the drawing window colors like those in the 3D parallel projection, 3D perspective projection or the command line context and interface elements. This is not available after trial has expired. 

Here is what it look like in AutoCAD Architecture. “Replace Z value with current elevation” is a button on the application status bar.

It is the system variable OSNAPZ that holds this setting. OSNAPZ was introduced in AutoCAD 2006 and with OSNAPZ set to 1 anything you snap to only uses the current elevation as z value. OSNAPZ controls whether object snaps are automatically projected onto a plane parallel to the XY plane of the current UCS at the current elevation. OSNAP command or OSMODE system variable in AutoCAD sets running object snap modes.

When installed as an AutoCAD app OsnapzBG Plus shows up on the Add-ins tab and gives quick access to also change the value of OSNAPZ.

Have any Drawing Window Colors changed based on the OSNAPZ value.

Usage of OsnapzBG Plus where drawing windows colors are changed when OSNAPZ is changed.
