Create a mesh from points on offset curves

[Ivan_Otero]

I am trying to create a quad mesh from offset curves on a plane (image 1). I split the curves and am left with a data tree of points (image 2). I want to connect the points such that for a given point, it is connected to the two neighboring points in the branch and to the corresponding point(s) in the neighboring branches (image 3).

I was thinking of using Weaverbird’s Mesh From Lines to create the mesh after drawing lines to connect the dots, but I don’t know how to parametrically connect the points in the way that I want. Is there a Grasshopper command that create a mesh from the points or draw the lines to connect the points in the way that I want? Or would it make sense to try making a Python script?

With two closed polylines, you can loft the segments and then convert the quads into simple meshes.

Then subdivide.

Thank you for the suggestion! I’m trying to implement it, but the resulting mesh has some triangular elements that I’m having trouble removing. Also, is there a way to control the mesh sizing so that I can specify how many elements make up the perimeter and the “radial” length?

Hey @Ivan_Otero,
This is what Martin meant:

Hence I take no credit, he gave you the solution.

You’re not doing what I suggested. The first step is to loft the curve segments, not the closed polylines.

The result of that is five meshes with four vertices each

Thank you @martinsiegrist @René_Corella !
