Hi,
V5
with a distribution of points on a curve roughly in the XZ plane, when I choose PlaneThroughPt to get an average plane through them, that plane is sloping a little relative to the XZ plane, to have an option in the command to make the result planar/parallel to XZ etc would be good.

Instead what is the best way to average then the result and tilt it slightly to make it planar to e.g XZplane ?

Select the plane and with Gumball on, set to align World or CPlane, click on the Y scaling handle, and type in Zero and Enter. Of course setting the plane to world XZ throws away the ‘Best fit’, so seems not terribly useful.

Looks like Steve1 needs the average of the point Y coordinates to locate the plane. Export a Points (.txt) file of the points. Import the file into Excel and use the Average function on the column of the Y coordinates.

[/quote] That does not put the plane at the average Y value of the points.
