HOW DO I GET BASIC RHINO COMMANDS INTO MY GRASSHOPPER SCRIPT???

Hi Y'all!

I have a rather simple, possibly stupid, nevertheless important question:

I see some of them in the menu (circle, etc.) but many seem to be missing...

I am trying to script MeshToNurb->Explode->Dup_Edge->SelDup->Erase

(convert an input mesh to Nurbs, eplode to single Nurbs, create the edges of those single nurbs surfaces, select and erase duplicates)

Do I use VBscript, what do I type in there, or: where do I find basic Tutorials on that?

Thx,

Roland

Not every command has made it into GH yet. However there is normally a way of achieving the desired effect even if you have to dabble in the dark arts of VB or C# script components to access RhinoCommon directly.

However, in most cases it comes down to a different logical process to get the answers. The way you do it in Rhino is not necessarily the way you do it in GH. In this case it would appear that you want the curves that represent the wireframe of the mesh. this can be done by decomposing the mesh and using the vertices to create polylines. But better still have a look at Giulio's Weaverbird: http://www.grasshopper3d.com/profiles/blogs/weaverbird-mesh-topolog...

Where there is a component that handles this very task.

Have a look at the other Add-ons available to Grasshopper from the download menu bar of this

site as there are some fantastic additions to be had. If you are doing lots with Meshes also have a look at [uto]'s Mesh Analysis and Utility Components. Kangaroo, which is a physics engine for GH, is fantastic but has the added benefit of coming with some utility components like RemoveDuplicatePoints and Lines
