I have a system comprised of Victualic fittings. There are lots of 10" SR elbows in this system. However as you can see in the attached catalog cut, these 10" elbows have a center to end length of 9".

After trying to adjust the bend radius to < 1, Caesar II doesn't seem to allow this. However, that's what these fittings are.

Is there a work around for this? I'd like to avoid having to adjust all the straight lengths to increase the elbow lengths just to make the program happy.
