4x common zone planes as datum

pcdmisstudent
hi guys
i just need to double check on u guys how u would measure this plane and level to it.
so its 4x planes with CZ (they are on same level to no need to do any offsets)
i measure the 4x planes as autoplanes
select the 4 planes in construct planes dialog and construct a bestfit plane
construct another plane using the BF plane, now i construct a "primary" plane with bfre and minmax option
and align to primary plane.

is this correct?
how would u guys do it

  • Create your 4 planes as normal autoplanes. Create a set and select all 4 planes. In the edit mode go to the line in the set that starts with "CONSTR/SET," and change the name of the plane i.e. pln1 to "pln1.hit[1..pln1.numhits]". This is an array of points extracted from that feature. i.e. in the case of my example I had 4 points per plane, so "pln1.numhits" = 4, so the array is "pln1.hit[1..4]", which tells PCDMIS to use pln1.hit[1], pln1.hit[2], pln1.hit[3] and pln1.hit[4]. Continue renaming the planes in the set to match. Then make a constructed plane using that set feature as the input.

    ...or just reference the PLN1.HIT[1..PLN1.NUMHITS] etc. in the constructed plane, no need to create a group first (unless you want to).

    So long as the center of at least 3 of the planes aren't coincident that will work. I posted the answer with a constructed set knowing it would work in all cases. If someone searching for an answer tomorrow only has 2 planes and needs a solution, the above will work.
