Step it out ...and then Step it into Inventor
I steped it out of AutoCAD, but it didn't come into Inventor. When I steped it out of AutoCAD it took like 1 second for it to convert it and save it, which seems unrealistic. When I opened in Inventor it was just blank.
Maybe a reinstall is a good method to try. I would need some guidance as to how to do that. I have a stand alone version of Inventor that comes with AutoCAD Mechanical. A reinstall would be nice because my content center doesn't work. Its empty when I try to access it.
can you attach the file, and you have to pick it for the step out ....
or you could open the Autocad file directly in Inventor,
but I'd love to see if I can open it ...
I did select all the lines of the part when I did the step out. It didn't make a difference. Unfortunately I can't attach the part because my customers would not be happy. They are very into confidentiality.
oh ...didn't know it was surfaces, did you see if you could change the transparent on the file you brought into IV ..
make sure you also have in the options, surfaces' clicked or it might not bring them in ..
I know you tried some options, but you might read this.
I forgot if you were able to step out and in a cube directly in Inventor (no AutoCAD Mechanical, only Inventor).
If this doesn't work there is definately a problem with the Inventor install.
