Arc length dimension??

Arc length dimension??

Arc length dimension??

(OP)
This has never happened before and I can't get it to happen again,but......

I this 1 particular assembly SW keeps giving me the wrong arclength dimension.

Using a very quick and easy (for me anyway) equation that uses 2 arc length 'driven' dimensions I determine what size v-belt I need to use to drive the reel. As I said on all but this 1 occasion it has work perfectly for me.

As you can see from the 2 attached pics, when I select the arc length dimension the value is correct(pic 1) but as soon as I place the dimension, the size changes to what appears to be the short side of the arc(the piece that isn't there)(pic 2)

OK no idea why the pics are not uploading.
I'm not getting error messages

RE: Arc length dimension??

When things like that happen to me it often turns out to be a sketch relation has been automatically added as things move around. Check to see if extra relations are in place for the one that does not work vs.the one that does.
