We saw this with one of our customers. It turned out that (we think) the update checked the "Use Auto Length as Entered Length" box in Main Database->Fittings->Pattern Options->Straight. If you unchecked the box and do a REBUILDALL in a drawing this has occurred it should correct the issue.

We've also had some customers report that this update changed the way Main Database->Fittings->Pattern Options->Straight->Option->Machine if Length< values read. In two cases it changed the value from 60 to 200 and in two other cases, it changed what that value needed to be. i.e. they used to have it set to 60 for a TDC to go to the decoiler, but now they need to set it to the finished length of 56.25. Hope this helps.
