Text alignment,

[Anonymous]

Has anyone got a way to set the text alignment to match the entities that is it attached to when you query in OD with a property alter query? I think David said sopmething about it back a few months ago and was going to get with the MAP team to find out. Thanks, Murph

I was looking for the same thing and found the original info posted by David...Here it is:

Hello,


Try the following expression in the Rotation
field of the Define Text Property Alteration
dialog:


(angtos (- (/ pi 2) (atan (/ (/ (if (> .y1 .y2) (- .x1 .x2) (- .x2 .x1))
.length) (sqrt (- 1 (expt (/ (- .x1 .x2) .length) 2)))))))


It is a rather big expression which is likely
to wrap in this message, so be sure to copy it
as one long line into the rotation field.


Limited testing, but it seems to work for
most linear entities (line, pline, arc).


Let us know how it goes-


rdh.

Thanks I knew it was there somewhere and my search of the NG turned up nothing.
