I have a question for all using V27. I use Alibre for reverse engineering and designing items for 3D printing. Because of this, I use GLP to tweek the design. When I dimension from a surface line and that surface moves because of a dimension change, the dimension to that surface line does not stay associated with the surface line, but to a construction line. Also, I make one line coincident to another line and when the line moves because of a dimension change, the line I made coincident to it does not, but stays coincident to a construction line. I am wondering is others have this same issue?
