Problem with Jig

Anonymous — Fri, 23 Jun 2006 17:42:41 GMT

As you can see, this Class inserts a Text with the actual length of a curve
at the cursorposition.
All works without any problems in wcs. The text rotates like it should. When
i try it in a ucs, the text sometimes rotates a little bit wrong, as i said,
sometimes and not allways.
I have no idea what i can do, any ideas?

Is your text insert point xformed to wcs? this can give you incorrect results when working in different ucs's.

Thank you very much, Alexander!
I've learned so many thing from your example that i was searching for for so
long.
It works like i wanted, no, it is much better.
