UNDO

Function

UNDO is used to reverse the last graphics command.

Remarks

In general, UNDO is able to reverse structural modifications involving commands susch as RING, CHAIN, FUSE etc. and the specification of 2D- and 3D-constraints.

It cannot undo changes to any of QUEST3D's files. Thus it cannot undo DEFINE-STRUCTURE, tests composed in the NUMERIC and TEXT sub-menus, STORE-FRAGMENT in the FILES menu, etc.

UNDO is especially useful in the BUILD menu, allowing you to redraw the structure with no incorporation of the last change made to it. In the EDIT menu it can be used to quickly test the effect of applied edit operations.

If you select UNDO a second time then you will be back to your original position.
