ziRail creates patch polygons along your strokes. These strokes are drawn directly on a mesh. By doing so, creating polygons become intuitiv. This can be used as a companion tool for retopology tasks. ziWireframe is shipped with it.

We’ve been inspired by Blender’s BSurface  

HOW TO USE
Source – Specify a base mesh. The newly created polygons will be snap on it.
As Reference – Will set the Source mesh as reference. That is convenient if you need to select the components of a mesh ontop of it

Uspans – Specify the amount of subdivisions along the U direction of the patch. This can be done before and after the patch creation. It will have no effect if you have created the last patch from existing polygon.
Vspans – Specify the amount of subdivisions along the V direction of the patch. This can be done before and after the patch creation.
