How to get "extmin" and "extmax" in rotated UCS?

"extmin" and "extmax" always show the data, based on WCS.

But how to get "extmin" and "extmax" in rotated UCS?

    Dear Peter,

    please see the (trans) function - it can transform a point / vector to / from WCS + UCS ...
    should work then...

    The OP has asked the same question here:
    https://www.theswamp.org/index.php?topic=54567.0

    @Peter2
    If you don't like the solution in that thread (still waiting for a response...) maybe you can do something with _Zoom+_Extents and then translate 'screen points'.

    Yes, I started the question at "the swamp", because I started with AutoCAD and Lisp.
    But under Bricscad I thought that there is maybe a special internal command for it, but regrettably not.

    I will soon answer at "the swamp"

    Well, the the alternative approach I have suggested will not work. Zoom extents also calculates a box around the WCS box defined by EXTMIN and EXTMAX.
