Hi there! I have some trees in Rhino created with LandsDesign plugin. Is there a way (in Rhino / grasshopper or LandsDesign itself) to create a 2D boundary line around them in the plan view? something like this: [image] [image] The above is just an example. In real life I will have the whole pa…

3 possible approaches - assuming it is more a graphic workflow you re after: Use Shrinkwrap (Rhino WIP V8) to generate a overall (3d) mesh that “packs” the group of trees. then meshoutline to get the curve. You can also do simpler stuff like this in 2d - use Affinity Photo or Adobe Photoshop. D…

Thanks @Tom_P and @AndersDeleuran for your suggestions! That’s so helpful! MeshOutline or Convex Hull would do the trick I think, just not sure how to get my trees to mesh form beforehand. I have Rhino 7 so sadly don’t have shrinkwrap. Exploding the trees makes them into open meshes, but computing…

ok but you’ve looked a the link posted already above by AndersDeleuran ? [image] Convex hull elastic band and circle packing? this thread? [wrapgrab] I think the quick and dirty version is: use a 100x100 square as size reference. photoshop - selection - make workpath - copy paste to illus…

How to create a boundary line from objects? (trees)

You can get the tree mesh vertices and compute their boundary using the native Convex Hull Grasshopper component. For concave hulls (i.e. like in your sketch) you can use alpha shapes:

Or dynamic relaxation (i.e. Kangaroo2):
