3D surfaces to flat

Im having troubles getting my shapes from 3D to flat. (2D?)

A friend helped me make a bumper with sketch up and exported it to autocad. Now that its in autoCAD, only the top and front/side shapes select and copy to a flat surface on another cad file. The other parts that are on "off" angles copy too but they are either wrong lengths and / or wrong angles.

So only the top and front views are giving me accurate parts layout. Am I copying the parts off the 3D view at wrong angles? And if so how do I do it at the proper view angles to copy?

Hard for me to explain. If needed, I can post a screen shot. Thx.

try flatshot command or flatten. Post screen shots pls.

Hi, thanks for the replay, here is a screen shot. The parts at the bottom and sides (ex. part with the hole in it) copy at weird shapes. They look right but when I measure them, they are smaller than they should be. The parts are correct in Sketch-up so Im thinking Im copy pasting them from the wrong view angle.

I tried those commands but they say unknown. Also when I copy the parts, I do pan to get a more straight on view but Im thinking its still not accurate enough.

I had the images redrawn on sketch up and imported which worked. Not sure of another way of going about doing it.

Thanks.
