I use TurboCad with SU for condoc creation.
Flatten the model and export as 3d dwg.
(2d export does not work the same)
Dimensions and leaders export as Tcad default and I just select and change formating to suit.[Edit/Select by/Entity type]
Text comes in as Tcad "Multi-text" and is format/content editable too.
Not parametric but a pretty good work-around for 2d and the price is right too.
Good idea to make both a 2d and 3d version of the model concerned.
Both dimensions and text actually come across substantially OK so do check it out.
