I have a box with rounded corners, open on top and bottom. I want to create a perforation pattern that wraps all the way around the box with equally spaced features. The first step is to create a point grid, but the surface UV curves are sized differently for each surface within the brep. How can I …

[image] dan14: find the length of the segments A way to attempt to do that is: Get the Surfaces sizes in U or V. Get the min or max (or average). Then for each Surface sizeU/V (and for given divisions uDiv, vDiv) get a proportional division value as follows (min is used): int divInU = (int…

This is a very clean approach. It works great for simple extrusions. Unfortunately, the application that I’m working up to has a more uneven surface (I reduced it to simplest terms in my original question to help me understand the approach). When the surface is broken or uneven, the contour approach…

At some point the definition needs to be freed up from any UV relationship, especially if there are trims on the surface or a polysurfaces where UV is not predictable. In this case you have both. In that case I use PanelingTools and create a series of sections around the object intersecting planes…

Follow up question, The actual target geometry in my application is a little more complex. Instead of being a straight extrusion, the box has an irregular cut in it. A loft (in Rhino or in Grasshopper) isn’t ideal because the unequal curves produce irregular UV curves that don’t follow a grid. If …

Loft does not equal vertical or promise verticality.

Using the original surfaces. Grasshopper does a bit of a cleanup on the Brep. Horizontals are sections with planes. Verticals made with vertical lines from a section across the middle. Using PanelingTools to create the Grid and the grid cells. Now it is an ordered set of grid cells. [image] H…

A little clean up on the original Brep. Same shape only the bottom cut out is a trim. You can see how using the untrimmed and trimmed test allows the panels to work around the trims. [image] You can find inner panels that are full quads and can be populated with the standard facade frame. Now …
