Keenan, The isolines grid seems to depend on the way the surface is constructed. (eg. The definition seems to fail in certain cases where the surface is derived from a sphere) I’ll need to alter the script and approach (to not use isolines) in order to obtain a regular grid irrespective of the geometry of the surface. However, if you want a non uniform grid, you could try the below file in which the input parameters for the spacing is a range instead of a number. File: [SurfaceSubDivision-1.dyn](http://dynamobim.com/wp-content/uploads/forum-assets/testingwaters/07/09/SurfaceSubDivision-1.dyn) I’ve also uploaded the same as a node in the Package Manager (Search for Testing Waters - _Surface.DivideByIsolineGrid_) ![20150709-1.dyn](http://dynamobim.com/wp-content/uploads/forum-assets/testingwaters/07/09/20150709-11-600x373.jpg) --- _[View the full topic](https://forum.dynamobim.com/t/is-it-an-adaptive-component-family-and-or-list-issue-segmented-glass-canopy/1676)._
