You have created a new environment that allows you to define the position and orientation of the model in the print space of the selected 3D printer. The commands to correct, align, and edit the geometry of arbitrary shapes greatly enhance Autodesk Inventor 2016's ability to design models with complex shapes. You can convert solid model faces to arbitrary geometry to improve shape. Many freeform part design tools have been added. Changing the DWG in the AutoCAD will change Autodesk Inventor 3D models.

The DWG geometry projection function allows you to obtain sketches that are associated with the original DWG file and use them for modeling. You can insert a DWG AutoCAD file into a part or assembly model and use it as a layout. Full multi-threading support enables Inventor to leverage hardware capabilities. The custom import feature allows you to read only the necessary data from part and assembly files and speed up the import process. Imported geometry in Inventor is updated as the model changes in native CAD. The technology, named by An圜AD developers, allows associative import of data from CATIA, SolidWorks, NX, Pro-E/Creo, and Alias files.

That's pretty common, actually, expecially in the LInux world. Not sure I've ever seen a program that you need to download another companies software just to use it.
