I can say the offset rules are for close offsets, it won't help you in this situation.
If you have the rules set up, this will make your 90 to 90 offsets go 45 to 45 instead when they get to a certain distance. When I get closer than 3" with an offset it puts in two 45 degree bends for me instead.
We finally got DL to work, and I was wondering about this myself, but we're better off using a script or LSP to identify the problem spots after the fill, searching for pipe lengths less than (X).
