When using the BIM exchange to export the chair we discovered that Revit did not particularly like fillets and chamfers (in fact there is a button dedicated to getting rid of them.)

So if you have a really complex model how do you get it into Revit. Well we can use one of the other file formats that Revit accepts. DWG or SAT. With the chair that I created I have recreated the fillets for my chair and also put in a nice plush cushion to go with it. This was created using the new Freeform modelling and it was as easy to create as apple pie.

Inventor Freeform modelling

Look at those nice curves Inventor created.

So to get this into Revit I use the save as function and I chose the .dwg file type and this is how it looks in Revit.

Revit dwg files

I can safely say that it is better to export as a .dwg than a SAT file. It doesn’t look particularly pretty.

I also opened up the Inventor part in AutoCAD to see if I could save it as a .dwg from AutoCAD and then send it through to Revit but it didn’t bring the cushion in so I stopped there. . So I think I will investigate that a bit further.

Look the curves have come through. Not bad at all.

I also exported the chair out as a SAT file and this is how it looks.

Revit SAT file

I can safely say that it is better to export as a .dwg than a SAT file. It doesn’t look particularly pretty.

Inventor to Revit Conversion

I think Autodesk has done a fantastic job in the file conversion game. There are so many different ways to get a file from one software package to another, you just have to think out the box sometimes.
