Set vertical position for a number of objects

I have a file with several dozen planes - simple rectangles. Surfaces if you will. Is there any way to select them all and make them all the same height relative to the c plane?

Thanks in advance.

Hi arail,

Try the SetPT command and use only the Z

select them all and use setpt in the z (or whatever plane you are using)

then use 0,0,[your distance from cplane 0 here]

or
gumball scale to zero, then gumball transform in the z your desired amount. I like the gumball method myself-

Excellent.
Thanks

you can also use ProjectToCPlane or Align.
