Lines on the surface appears after I Cap the object

Before I cap the object, there are no lines on the surface after I cap the object, there are lines appearing on the object.

How to resolve this issue?

Hello- the initial object is an extrusion object - these do not show isocurves.,Cylinder%20create%20lightweight%20extrusion%20objects.

On capping it becomes a polysurface, and these do show isocurves on the faces. If you want to turn them off, you can do so in object Properties.


And yet another example as to why extrusions should not be turned on by default… jus’ sayin’… :wink:


I will bring it up with the large (and in charge) brains.
@Helvetosaur - it was a tough crowd.
