CAD Model help

[[To...]]

I have model of a rectangular part with a surface on top. My X and Y zero is based symmetry constructions of the 4 sides but I want to set Z zero at the highest point of the surface at X0Y0. The Z origin of the model is above the surface.

How can I determine where this point is on the surface?

Tom,
If I understand what you are asking, I believe you could do this using a Maximum Feature construction. I am interpreting this as wanting to know the x,y coordinates of the true high point of the top surface, while also grabbing that maximum Z to use as Z origin-if that is not what you meant, please correct me

Thanks for the feedback however, I am looking to set the Z origin with a single point at X0 Y0 but need to define the nominal of that point where it is from the model. I will be taking space points for SP distances at various locations on the surface.

I think I just solved my question. I created a FFS and theoretical line in Z direction and created an intersection of both.

If you need the Z height at exactly (0,0), this is the best way to do it. intersecting a feature with a line is the best way if you need to know the value at some exact set of coordinates, for anyone who may come across this in the future.

What type of Base Alignment are you using? Wouldn't a 3d Best Fit get you what you want? It will keep the origin at the CAD origin for you.
