Template:Problem solving planar

Creating planar surfaces may fail for various reasons. Note that the geometry node for the surface is still created despite of any errors that prevent the surface from showing. When you get a failed to compute error, undo the last action or fix the problem immediately. In this last case you don't need to select the planar command again; the surface should appear automatically once the problem is fixed.

• Curve(s) not closed

If the curve or curves aren't exactly closed, you won't be able to create a planar surface. There can't be any 'leaks'. To check if a single curve is closed (or periodical), you can check the Attribute editor:

Solution: close the curve. Either manually (using point or curve snap), or using Edit curves > Open/Close curve.

• Curves are not planar

If the curve(s) for you planar aren't absolutely flat (planar), you won't be able to create the surface.

Solution: If the curve isn't flat, you may be able to make it flat by scaling it to 0 in the desired direction. Or you could align all vertices using point snap to make the curve flat.
