Another Datum Target Points Disaster Print

Lukas
Good morning all,

I am looking for some input on how you would program this. Datum A is the midplane of the part using target points at specified locations from Datum B. It doesn't help that Datum C makes zero sense hah, so I left it off of my drawing. I am pretty lost in terms of how to do this correctly (iterative alignment?)...at this point I'm am considering just making planes (with many hit points) and a midplane for Datum A.

  • Right, I just realized that I can't create a mid-plane for B because I don't have enough points to create planes on each side. I was thinking I could just probe a ton of points on each side of A and ignore the datum target points. It's funny, the engineer is using datum A (and only datum A) for the majority of the FCF's.

    I wanted to do an iterative alignment for this program, but I don't understand how I would do that. Apparently you can't use a cylinder as your primary leveling feature in an iterative alignment. I wanted to somehow mix 3D features (Cylinder) and target points in an iterative alignment.

    What do you think of this: probe Datum B as a cylinder, level and translate to the cylinder. Then probe a random rational line (the print is almost useless for rotation), rotate to that line. Then key in the datum target point locations, create a line on each side of the part using those points, create a mid-line, and translate to the midline.
