Can you flatten an extrude?

[jarjones]

I have a group of 2D polygons that have been extruded.  The extrudes were then added together and pushed and pulled and rotated to make it fit another 3D shape.  Now I need a 2D shape of the extrude. 

 

My thought was to go back into the groupings of added extrudes until I got to the original polygons for the extrudes and copy those out and paste them back together and add the surfaces, but when I try that, they lose any rotations or scaling that I had to apply while in 3D mode.  Is there a way to get the 2d shape easily?  I'd rather not try to rebuild the shape in 2D.

 

Thanks,

Jeff

The quick way to do this is to use the Extract tool.

1. Just run the tool
2. Set the tool options to Create Planar Objects
3. using the 4th mode (extract surface mode) 
4. Hover over the Solid Shape you have made and select the face that you want to extract
5. Press the check box in the mode bar or press return and a 2D Polyline will be made.

That is the best way to do it.

An alternative - that's useful for non-planar objects is to set up a view you like

Align Working Plane with Current View

Modify>Convert Copy to Polygons (Hidden Line Rendering)

Modify>Ungroup

Add Surfaces
