Boolean Operations on Polygons
 

I'm creating my RJ-45 jack from scratch and i'm trying to use the boolean operation of difference but keep getting an error. Can someone help out? I don't get it.. it should work right.. :S


The error...

select -r polySurface12 ;
select -tgl pCube7 ;
polyBoolOp -op 2 -ch 1 polySurface12 pCube7;
// Error: Cannot perform boolean operation //
// Result: polySurface13 polyBoolOp4 //

I have also attached a screenshot.

P.S Thank you in advance.

(as you can see i want to make 2 ditches at the bottom)

can you highlight which two your objects your tying to use?
