Has anyone ever had the problem in inventor, when you open an autocad dwg file, the options button is greyed out and you can't chose or change anything?
Open the DWG in AutoCAD Mechanical - save it as an IGES file - then import the IGES file into Inventor.
(Tends to make stupidly large files - quick sketch and a revolve is a MUCH better suggestion.)
Hey thanks Peter,
Initially I had trouble exporting from AutoCAD to iges as it didnt export some of the wireframe. I think it had something to do with surfaces or something (I have very limited autocad 3d moddeling experience so not too sure)
In autocad I then exploded everything I could, there seemed to be blocks within blocks. And then saved as a STEP file. It created a single solid which is usable in Inventor. (for civil foundations)
The part created is opaque, so im not sure how to get looking like a solid. Changing the colour didnt help.
So ive almost been sucessfull, and almost there.
Any advantages in using IGES over STEP?
Right-click the surface model in the Inventor browser and remove the tick from "Translucent" - but it's still a surface model.
Really - the time you've spent on it so far would have been much better spent modelling it as a couple of sketches and features! (Have you had a look at look at the file size?)
Not a problem, the ipt file created is 4mb
The issue is the dwg file is complicated enough to not want to reproduce the work again. The AutoCAD files are supplied by a 3rd party, I would rather import thier data than risk making a mistake reproducing it. I also hate having to do things twice
For myself this is likely to be required more often in the future, so I would rather spend a little time figureing it out now and save time in the future.
