Ai to DWG to inventor - won't extrude - This worked for me.

[lch]

Hi.

I often receive Ai drawings (Adobe illustrator) or Pdf, that i am converting to dwg.

Mostly so i can make an extrusion in inventor.

Often it happens that inventor won't extrude the converted drawing.

As other post describes you need to check on "Constrain end points"

Uncheck "Import Parametric Constrains" when importing to inventor.

But this was't enough for me to do the trick.

It still wouldn't extrude.

So here is what did the trick - for me at least.

Open the DWG/DXF in autocad.

Be sure to explode the drawing/lines - you may have to explode it more than once (depends on the number of blocks).

Also be sure that all unused lines are deleted. 

Save it again and import it to inventor.

Now it will extrude.

Hope it will help you too.

Can you provide .dwg example which reflects your problem with extrusion feature?

This one should show the problem. (test.dwg)

I need to explode the curve 2 times in autocad to make inventor extrude it.

Hello,

Yes, you have to explode the profile twice, first time because of the block (or you just can edit a block), second time because your spline which represent "arc" consist of several splines which are not connected properly.

You can convert it to polyline and profile will be imported as closed. Of course, you have to check "Constrain End Points" checkbox (as you said). Be careful, because sometimes converting to polyline creates a more complex surfaces in Inventor (because of many segments), so updating a part could take a time.

You can use command "overkill" to remove all overlapping curves, but be careful with "combine options" cause they can move a sketch lines and curves little bit to create constraints. It's all about the tolerance that you want.
