What I miss is the ability to create a glazed screen with a door and opening lights in it and that lets you choose a UK style of opening symbol for the 2d elevation.
I also find that the "Sketch Window" is not reliable at picking up mullions and transomes where ArchiDesigner was and you even had a facility to interact with it as you created the object which AG doesn't allow.
My other gripe is with the Curtain walling profile. We often use silicone glazed assembly which results in only 20mm of metal showing externally but with a 50mm wide box internally.
Still looking?
