Is there any good modelling software that supports dimension and has built in scale capabilities? I currently model in Wings 3D and Hexagon, whilst using a 2D program to make dimensioned drawings and export them to the applications, but it is becoming very tedious and difficult to model by eye balling the model to these drawings.
My ideal would have been Amapi 8 as it has both Nurbs and Subds, but is dead

. Amapi 7 lacks the edge loop coolness that I like, but I might go for it at this price

From the demo it seems like I cannot extrude objects by x mm and keep dimensions visible which I do not like.
Does anyone have any recommendations (nurbs or sub-d or both)? I looked at the Modo site and it did not say anything about dimensioning.
Thanks.
