Problem Extruding shapes imported from illustrator

[Aquaguy]

Hello.

I've created an object containing several shapes in Illustrator CS6 and exported it as a DWG, In Autocad 2014 I've exploded the block using XPlode command, now I want to extrude this shapes so I can create a geometry and start doing booleans and so one.

When I click in the Extrude option and select any of this shapes I get an error saying that objects of this type can not be extruded. I'm completely stuck I've been going back and forth from illustrator to Autocad 2014 and I can't find what's wrong.

Could you please tell me how to proceed?

P.S. The shapes in Illustrator have no stroke or filling so you will have to "Select All" to see the whole thing. The DWG and AI files are inside the attached zip. The DWG has been exported using "File > Export" w/ "Maximum editability" from Illustrator.

Welcome to the forums.  I don't use Illustrator, but in the dwg, all the objects (16) appear to be blocks.   After EXPLODEd, the polylines and splines should be able to be EXTRUDEd.

Where can I see the object type? I'm 3D Modeling view.

There's a "Quick Properties" toggle on the status bar that you may find useful.

PROPERTIES at the Command line, or CTRL+1 will open the Properites Palette and display the object type and properties when the object is selected.

Thanks to your help I've been able to extrude most of the splines (all but 4).

When I try to extrude this last 4 splines I get the following error: 

Select objects to extrude or [MOde]: _MO Closed profiles creation mode [SOlid/SUrface] <Solid>: _SO
Select objects to extrude or [MOde]: 1 found

Modeling Operation Error:

Sweep self intersects.

Unable to extrude the selected object.

What can I do? Thank you all
