constraints problem

constraints problem

constraints problem

(OP)
I have constrainted to parts ( NX5.04) new constraints with angle between the bodys , look atached. When I use the expression editor to control the angle, the angle does not really update how I expected 180 works but for ex. 175 an 185 are the same.
Are there any workarounds to deal with this problem?
thx in ad

RE: constraints problem

For some reason the angle is flipping when you change it using the expression.  If you select the angle constraint and change it in the on-screen dialog box it seems to work OK.

I found a workaround that works around :)
I ve changed the the constraint connected the edges to distance=0 ... and it works winky smile
 but what is there reason for this behaviour-
 works as designed or ???
thx

- found out the big is the expression editor doesn't update correctly the expression created in the from constaint dialog. Update from the constraint function dialog works correct. never user the expression editor with constraints...
