There are several commands in Rhino which have mesh splitting capability, but we’ve had limited success with them in the past. This definition works for splitting a mesh with a set of a curves (lines, polylines, compound curves, etc.) by using a series of steps as described in the list below. The sample file we’ve uploaded is set up to work in the XY plane, but can be quickly edited to work with other planes.

Rhino for E57 import, explode, *.Iges out. Solidworks for iges open and product design. Working with a mess of points is difficult, and I'd rather have a mesh out of Rhino. Mar 21, 2014 Learning Rhinoceros.3D ---Mesh Point Editing cadxneter@hotmail.com. The InsertControlPoint command adds control points in a curve or a row of control points on a surface.

Splitting a mesh is often difficult when dealing with Sketchup geometries or Revit toposurfaces, and you may have heard us write about this earlier in our post. This definition will work on continuous geometries which are also one-to-one functions (the geometry does not have holes and has a unique x,y value for every point on the mesh). A site topography almost always fits these criteria, so this definition will help for trimming and splitting these meshes. Here’s a quick run-through of the definition’s process:. Select Mesh to split and select splitting curves.

Triangulate Mesh. Some non technical topics. Project naked edges of mesh onto the XY plane to create a planar surface. Project splitting curves onto the XY plane and split the planar surface. This isolates our regions, now we will recreate our meshes based on their containment within those regions.

Test all mesh points for containment within each region. Project splitting curves onto triangulated mesh. This gives us a polyline for all curves since all mesh faces are planar. Test polyline points for containment as well.

After testing these points for containment and grouping them based on each region, we can then recreate each mesh with Delaunay triangulation. download id=”28″ Obligatory disclaimer: the author does not guarantee that these parametric models are bug-free or that they will solve all of your problems.

Mesh+ is a set of user objects which enable a wide range of mesh editing, creation, interaction, and topology modification within Grasshopper 3d. You are correct, the component's tool tip descriptions were incorrectly labeled. The components did not have list inputs as an options. However, I've updated this for the Weave, Link, and Net components, so that they can now have vertex based values.

The Loop and Thatch components, still have only single value inputs. You can download the new component set from As a side note, because the components are all VB nodes, changing the inputs types without altering the actual scripts will always cause an error because they are used in the scripts specifically as either items, lists or trees.
