How to remove the gaps?

Help is needed!
Painted using a contour of an object (“Twisting” tool).

It seems everything is OK.

But when approaching the edge, you see gaps.

How to fix them?

Hi Russlav - this can be cleaned up by setting a more accurate display mesh - please see

With this window:

I got to reduce the gap, but not completely. There is something else? Thank you!

Hi Russlav- you will always be able to zoom in enough to see gaps at some level. The best control is the ‘Maximum distance edge to surface’ - set that to .1 or .01 and see how it goes.

The gaps can not be removed completely?

Correct - but that is because the render mesh is not the surface:

http://wiki.mcneel.com/rhino/meshfaqdetails

"Although Rhino is a NURBS surface modeler, it uses polygon meshes created from those surfaces for visualization purposes. So what you see on the screen when the model is shaded is a special, invisible polygon mesh (the render mesh) that is attached to the actual NURBS surface.

Why? For quick shading and rendering. While a mesh has the advantages of shading speed and adjustability, there is a disadvantage. The render mesh is always an approximation of the surface, so there are almost always gaps between the faceted render mesh and the actual smooth surface."

-Pascal

There is no physical gaps. Just visual.

Thank you!
