Hello, I am currently dealing with the Unroller class . I wish there would be more options to attach metadata to the geometry when unrolling. For example, I have two lists of text dots I wish I could attach separately, because they refer to different properties. Let’s say I have two lists ([textdot0…

Hi @PaulPoinet , The Unroller class is pretty 'rough` on geometry and, thus, difficult to make user data survive or even know what output component to move the input user data onto. If TextDot user data would survive the unroll, would this be helpful? – Dale

Hi @dale , Thanks for the reply! Yes indeed it seems difficult to make user data survive. I have been trying for example to attach points that are not onto the brep to unroll and I noticed that those are dismissed. TextDots survive the unroll already, but what would be helpful is that the order is …

Hi @dale , thank you! Sounds like something very useful for my case. Sorry I missed that!

Rhino unroll method by default joins unrolled surfaces. Let say I have a cube and when I unroll I can get 6 separate surfaces or one one joined cross like geometry. Does unrolled class has such a property to join surfaces as rhino command?

Use Unroller.ExplodeOutput . – Dale

Well, sorry if we switch topic here. I currently input brep strips composed exclusively of triangles. Even when I set the ExplodeOutput to false, the result is constantly exploded (see bottom). Any idea @dale what I am doing wrong here? [unrollclass]

Hi @PaulPoinet , I’m confused. Are you expecting Unroller to join surface that were not originally joined? – Dale

Hi @dale , I expect Unroller to unroll a joined polysurface (when setting ExplodeOutput to false) that was originally joined. My screenshot above shows each Open Brep unrolled as series of Trimmed Surfaces. Maybe this is expected behaviour? Best Paul

Hi @PaulPoinet , An open Brep can very weill also report as a trimmed surface if the Brep contains a single, trimmed face. You mentioned that you had a bunch of triangular, which is as I describe above. – Dale

Request: Could we get more options to attach metadata to the unroll class?

Hi @PaulPoinet,

Just curious, are you familiar with Unroller.FollowingGeometryIndex? Here is an example:
