01:42.18 jarray52 Is it possible to create parts in Autodesk Inventor Professional 13 and import the parts into brlcad? Once the parts are in brlcad, I would like to be able to manipulate the parts as though they are native brlcad generated objects.

02:25.29 brlcad jarray52: as with most conversion questions -- "it depends"
02:25.43 brlcad yes there is undoubtedly several ways to import the parts into brl-cad
02:26.15 brlcad step, stl, 3dm, and dxf come to mind first, but there are probably other ways
02:26.56 brlcad you'll export from inventor to one of those formats and use our corresponding [something]-g geometry converter
02:27.32 brlcad manipulating the objects in brl-cad as "native" generated objects is the tricky part and depends entirely what you need to do to them
02:27.48 brlcad moving them around, rotating them, using them in boolean combinations is all fine
02:32.03 brlcad step and 3dm will import as immutable nurbs surfaces (you can't *edit* the surfaces, but you can use/move/csg them)
02:33.02 brlcad stl and a slew of other surfaces will import as polygonal mesh and are editable surfaces, but the editing features are experimental/cumbersome (and you can use/move/csg them)
02:33.46 brlcad dxf will be a polygonal mesh or extruded sketches
02:51.03 jarray52 brlcad: Thanks. One of my main goals is to scale the parts based on some parameters. In order to do that, I need a somewhat good representation in brlcad. Are there any non-native formats that import nicely into brlcad?

14:11.32 brlcad jarray52: scaling should be no problem with any of them so I'd suggest a format that preserves the original geometry as much as possible (step, 3dm, dxf probably in that order)
14:11.47 brlcad exporting solid ap 203 step data from inventor would probably work best
