Topic: Making a tool operate trans-parently

[ScottMC]

This is what I currently use but would be so helpful to be able to pick/turn my Z axis transparently. ANY SUGGESTIONS APPRECIATED!

MickD, "New UCS"  was where it came from. This is was I currently use to turn my Z.

Code: [Select]

(defun c:ur nil           ;; Z - 90°, # or Pick
        (princ (strcat " New/Pick \"Z\" UCS, Angle or <90"(chr 176)">"))
    (vl-cmdf "ucs" "z" "\\")
(princ)
)

Now, attempting other ways, seems it's a 'no-go'

Command: 'ucs
** That command may not be invoked transparently **

Not quite what you wanted, but similar outcome....

Results..

Command: L
LINE Specify first point:
Specify next point or [Undo]: 'UZR

Rotate UCS Z axis by 1-pick 2-enter angle (1/2)  <1>:

Pick base point...
Next point...
Reset UCS to World 0-No 1-Yes (0/1)  <0>:
_ucs
Point or option keyword required.
; error: Function cancelled

Wouldn't work/allow transparent to rotate ucs.
** Running A2K **

Sorry about that, I didn't know you wanted to change the UCS in the middle of a command.  That doesn't work in Acad 2018 either.

If you are using this to draw line segments or polylines, maybe a program that captures the geometry, allows UCS changes between point selection, then builds the lines or polylines after completion?
