Text Rotation

[rad.77676]

Does anyone know how to query object data text "roadnames" so that they come in aligned to the roadway, not all rotated to zero.

Watch for word wrap but try this expression as the rotation value.

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

Thanx J,
I found this on the acaddiscussion site and It has no effect.
Maybe I'm doing something wrong?
I tried pasting it into the Alter Properties, Text Value, Rotation Box with no effect.
I also tried Alter Prop, Rotation with no results.
Any suggestions?

I'll double check the expression when I get back to the office (where MAP is installed) You didn't included the quotes " " did you?

I checked and it works in Map3D 2005 here's a copy of the orginal message from the Map News Group where I got it from. Make sure the layer, text size, and text styles are set to where you can see the results also.

Tested again, it works!
Thanks,

Not sure why but I can't seem to get the expression to work. Every thing comes out at 0 rotation. Also when I go back to edit the template I get errors (Check for possible mismatched data type in the expression.).

Any ideas?

Word wrap or you're missing a closing ) or the " " are there and not needed.

No word wrap, all ")" are accounted for, and no " ".

I just tried it again and it's not working here now either. ?

It may in the anno blocks it doesn't work, but in a query alter prop text is does. Wonder why the block anno will not take it.
