Hello

Imagine a diecast box with bosses that stick up through the circuit board
trhough holes in the circuit board.  The shape of a couple of the bosses has
to change to let the mold flow better, so now the shape of two of the holes
in the PCB have to change.  I set a section view in the assembly at the PCB
bottom face height, so it "trims" off the bosses.  I want to offset (in the
plane) the trimmed edge of the boss and have it provide the clearance hole
in the PCB.   I thought I could set a new sketch at the cut plane- I know I
can't use the actual cut face- so I used a plane the same height as the
bottom of the PCB.  I select the edges of the cut-off bosses and try to
"convert entities" so I can use these in my new sketch, but it won't let me.
I tried one segment at a time, and selecting the whole chain one after
another.

Am I way off here?  Can someone please point me in the correct direction?

Thanks

Bill

Bill,

One way to convert edges on a cut plane is to insert a sketch on the cut 
plane, choose Tools, Sketch Tools, Intersection Curve.  Once you have 
converted the plane-surface curves you can convert to construction 
geometry and then offset the construction geometry directly.  This will 
remain parametric as long as the surface/body to plane segments remain 
contiguous.

Thanks very much.  I'm going to try that in the morning.
