extruding shapes imported from illustrator

[nadph10]

Hi,

I'm currently having some trouble using Illustrator shapes imported in Autocad 2013. The shapes are created using illustrator CS6 (no line / no fill), exported for Autocad 2004/2005/2006 as a dwg file. This dwg is imported as a block in Autocad without trouble. The shapes appear in Autocad as Splines. OK.

I designed a shape (using illustrator) that I want to extrude in Autocad, I can import it, it is nicely displayed as a spline, but the problem is I can't extrude it.

So I tried to do the same with simpler shapes :
- Square drawn using square tool -> Ok, can be extruded
- Circle drawn using circle tool -> Ok, can be extruded
- Hand drawn polygon using plume tool (closed shape) -> Ok, can be extruded
- Hand drawn shape with some curves using plume tool (closed shape) -> CAN'T BE EXTRUDED
- Complex shape (square and circle partially merged together using pathfinder) -> Ok, can be extruded
- My shape (heatsink section) closed shape -> Can't be extruded

You can see shapes here : http://img812.imageshack.us/img812/5466/capturedcran20130111162.png

It mostly works, but it seem that I can't extrude shapes that have hand drawn curves ?

Has anyone already experienced this ? Am I missing something (Autocad Newbie) or is it an incompatibility issue ?

Thanks for your help,

Julien

Precision could be from 1 (less accurate conversion) to 10 (the most
accurate).
When it asks "Enter an option" - just hit Return to quit, as conversion
from Spline to Polyline already done.
BTW: you can call PEDIT and then enter M for multiple in order to convert
multiple splines at once.

It worked! it totally worked! Thank goodness! I just left the precision at 10 and just pressed enter when it said to choose an option. I suppose 10 is heigh enough? I started at 35 but my computer couldn't handle it. it seemed to do fine at 10 and it looks ok.  

Thanks a lot for your much much appreciated help!

good tip for the multiple pedit command.

how did you correct the open polylines and the self intersecting polylines?

Thanks,

I did it manually for self-intersected polylines, and I closed open
polylines via properties palette (select all polylines scroll to the bottom
of Prop palette and check-mark "Closed"
