Hi,

I was wondering if you could help me with this problem. I have attached my assembly and parts. I was able to get X=40.24, Y=24.33 and Z=19.75 However it says the answer is C and i am wrong with Z=20.75. I do not know where else i could have put the origin to move the Z 1 unit without compromising the rest of the center of mass.

Once I sorted out the Pins, fixed the mates & gave them the correct material, I found you have your "Coordinate System1" in the wrong place. You need to move it over by 1mm to the virtual corner of the part & not on the radius blend vertex. Then you should get the correct answer.
