frontview with smart ucs that uses same origin

vandenoosterkamp — Sun, 22 Mar 2026 08:36:31 GMT

I'd like to be able to switch from a topview to a frontview and have the ucs origin point in the front view at the same place as it was in the topview. Every time I switch to frontview the program zooms out and sets the origin of the new ucs at 0.0

I know how to save views etc etc etc so I do not need tips for workarounds but specifically when switching to front view a usd that keeps that same origin because after that I can zoom to my objects. Ideally that would be automated as well. So I think lisp is the only way to get this?

Put this into an AutoLisp command definition, or simply a command macro in a Tool Palette button:

UCS

ZAxis option

{Enter} to accept current Origin

0,-1,0

That changes the UCS from, for example, this:

to this:

Same origin, different axes. NOTE: It's sensitive to Object Snap, so do it with that turned off, or build a "_none" Osnap call in, or something.

Hello,

Is UCSORTHO set to 1 instead of 0 ?

That may cause some misunderstandings....

It is a variable that takes the power.

Do you call your new UCSs with the words "top" "right" "front" etc ? or with the X or Y or Z option + double ENTER ?

How do you change or intend to change them ?
