Create hatch pattern from a curve

Hi,

I see that hatch function through rhinocommon is:
Hatch[] h = Hatch.Create(C, 123, Rhino.RhinoMath.ToRadians®, S);

123 - hatch pattern index.

How should I start if I would like to create hatch pattern myself when user input some curves?

I know that there is possibility to import hatch patterns from cad for instance, but I want to create hatch pattern myself.

Dear Dale,

Thank you for a reply.

I see that in rhinocommon there is function:

Rhino.RhinoDoc.ActiveDoc.HatchPatterns.Add(…

Is it possible to create hatch pattern through rhinocommon or only option is to create .pat files?
Second question is it possible to include polylines in hatches, when I explode them I always get lines and joining them take quite some time.

There isn’t any interface in RhinoCommon to create hatch patterns on the fly, which leaves you with having to read .pat files.

I don’t believe so…

So we have added some new Grasshopper components that can use lines and tiles to create hatch patterns in Rhino. More can be found in New Component: Create Hatch patterns with Grasshopper in Rhino 9
