WBcatmull clark subdivision faces

Grasshopper
1

Hello All :slight_smile:
I attached a jpg , 3dm and gh file of my problem.
I am creating a Meshplane with 3x3 faces. Afterwards I’m subdivide it using WB Catmullclark which automatically increases the nr of faces to “n” in order to create a smoother surface.
Question: Is there a way to control the nr of faces? lets say I got a 3x3 faces meshplane and after I subdivide it I want to get 19x19 faces.

Thank you,

Cheers :smile:

@ogprostean, i don’t think you can control that, the nature of CatmullClark is to divide each quadrangle into 4 new quadrangles and each triangle into 3 quadrangles (with each iteration).

Hello,
Thank you for the answer.

I was thinking mby there is something similar to the loopcut ( evolutetool) command that you can apply afterwards.

( actually I need a specific nr of curves not faces. ) the only problem is that loopcut breaks the symmetrie/ distance between the curves .
