alignment

[dea3cmm]

hello everyone.

i'm trying to make an alignment for a car frame.
i have 2 datum holes at the front and 2 slots at
the rear, 75.0 mm difference between the two.
how can i create a plane and level to it.
and what would be best to rotate to.

thanks for the help !!!

I take it you have no fixture for this, if not it sounds like you need to do an Iteritave alignment on the frame. Do you have CAD, surface/wireframe data. ??

[dea3cmm]

yes i have cad, no fixture. but i was looking at trying to
align without iterative.

can you create an offset plane?

[dea3cmm]

not really sure how to do it. i measured the front 2 holes, constructed
a 3d cylinder and level to it. but does not work out.

A little more info would help. What version PcDmis are you using? You mention that 2 of the diameter are Datums. Are the slots datums also?Are the Diameters and slots in the same work plane? Are they symetrical? A picturewould be great. let us know.

Curioius about what you found out. The problem didn't sound to hard but has me intrigued.
