V6, box edit, resize to zero not possible

Hi All,

A common part of my work flow in Rhino V5 is to project a curve to a curved surface then use Box Edit to flatten the curve in the Z axis - by setting the Z size to 0.000mm. I then use this flatten curved to extrude a solid.

I’ve run into a problem with V6 box edit in that it will not let me enter a Z size of 0.000mm - 0.001 is OK, but not to zero.

Is there a someway for this ‘problem’ to be fixed? Or is there another way I can flatten these curves?



An easy way to flatten a curve is by turning on its points, selecting these and then running SetPt on them.

You can also click on the Gumball Z scale handle and enter 0 in the box.
