Not sure what’s happening here, but it’s messing up my ability to use the tree. I’m using Contour. How the tree goes in: [input] How the tree comes out: [out] Jumping from 5 to 10 to 15 in the middle branch is kind of weird, no? The other inputs to Contour are single items. Why does this happ…

[image] Raam: I’m looking over your Anemone script I think I understand it except for the part with Plane through Shape and Brep | Brep. This seems like a very roundabout way for creating the Direction (N) parameter for Contour. If I feed the geometry from the Rotate component directly into the …

so what the contour component does is renumber the paths so {a;b;c} is item b in the original list. [image] The other issue I run into is no intersections on the first two diamonds. [image] you will need to fix it for the trim with region to work properly. I would recommend using another “tre…

Interesting, will look this over. Why does contour do that?

Behaviour seems like a bug. Numbers should be matching since it seems to be matching the first item in the path, but not the second. @DavidRutten this seems to be a bug in the contour component.

[image] Raam: Interesting, will look this over. Why does contour do that? As the output says “Resulting contours (grouped by section)”, it is doing something different. It seems to me that it is taking the last index of the original branch, adding the global index (DA.Iteration) and finally t…

I struggled for awhile to get an elegant solution, saw the data tree conflict and finally gave up. This is slow (7 secs.) but effective. There is a Data Dam (red group) with a two second delay to allow adjustments (blue group) to the length and angle of the white line which is perpendicular to the…

Sometimes it’s hard to see the forest for the trees… This simpler method is 1.8 secs. instead of 7 secs. [issue_2020Dec19c] issue_2020Dec19c.gh (38.7 KB)

Interesting way to use Perp Frame. Also hadn’t seen the Data Dam trick before. Not sure if this thread counts as duplicate. I’m only asking about this one specific confusing behavior of Contour.

[image] Raam: Not sure if this thread counts as duplicate. It looks like a duplicate to me. Several versions later… I tried the two shapes you used in the other thread and immediately saw issues so resorted to Anemone to handle one region at a time. Appropriate line length is determined au…

Possibly use data viewer:

Look at your N and D input.
