How can the DS Mechanical add-on modules help me?

Exchange Module:
    -> Edit imported STEP and IGES file geometry
    -> Export geometry to STEP and IGES files

Drawing Module:
    -> Create or View 2D drawings with support annotations (notes) and full GD&T
    -> Thread tool – create standard & custom threads
    -> Custom drawing sheets
    -> Create and insert barcodes into drawings
    -> Create and modify perspective views on 2D drawings from a 3D object

Bundle Add-on Modules:
For users wanting it all, an economically priced bundle (Exchange + Drawing) is offered as well.
    -> Edit imported STEP and IGES file geometry
    -> Export geometry to STEP and IGES files
    -> Create or view 2D drawings with support annotations (notes) and full GD&T
