Best practice: Import of inventor ipt into Rhino

Grasshopper
1

Hi All
Could I get some feedback as to the above title? Im wanting to create a workflow as most work I do is parametric and usually casting moulds. Currently inventor is my go to and does 95% of my work work with no issue. Im open to change…but thoughts appreciated

EDIT…sorry this probably belongs in another forum…Ill move it shortly

Hi there Wesse,

I don’t have a direct workflow for you but I wanted to let you know that I have had issues in the past creating geometry in Rhino and having it work properly in Inventor/Nastran.

My purpose was to model complex connection 3D geometry and import in Inventor/Nastran for modelling and analysis. The issue was that once in Nastran at times closed filled polysurfaces would not import correctly as full solids. Or the holes I split into plates where not being recognised correctly as full bolt holes.

When I modeled the same in AutoCAD using Extrude and Subtract I had no issues. I prefer to use Rhino in general and this could be just lack of knowledge about polysurfaces and solids from my part but good to take a note of.

Thanks for that info Arthur.
My main issue is using grasshopper as a surface finishing process in this case as there is nothing procedural that can be achieved simply in inventor (that I know of)
So are you using any parametrics in Rhino or is it usually single pass modelling and static modelling structures out? ie making parts for assemblies vs parametric objects?
Cheers
