Cut a section out of a 3D object

[jlovgren]

Hello all,

 

If I have a simple rectangular shaped 3D part and I want to cut the ends off at exact dimensions, what would be the simplest way?

 

If I draw a Polyline from the end of the part angled down to the bottom at my specified dimensions, can't I just extrude that line through the rectangle and trim it?

 

For some reason I can't make this simple task work. Please help???

 

Thank you,

Jason

Have you played with the slice command?
