"No luck. Could try using closest point, but it's only going to work in some circumstances."

"Did this work for you? I haven't had any luck making this Python Script work. import rhinoscriptsyntax as rsprojCrv = rs.ProjectCurveToMesh (crv1, mesh1, (0,0,-1)) I get this error: {0;0}0. Runtime error (TypeErrorException): iteration over…"

Alexander Robinson replied to Alexander Robinson's discussion UPD Limits Reached in the group gHowl

"From Grasshopper to Processing. The error shows up on the <UPD> Owl component and basically says that some limit has been reached somewhere. I've also reached the limit in processing, so I used a text file. Ideally I'd…"

"You are doing this on your own machine or from one machine to another? Which program are you communicating to/from? How many points to you need to send/receive?"

UPD Limits Reached

I'm running a routine that sends or receives mesh points as a String and I'm reaching a max send of about 2000 3D points. Is there any way to get around this and send bigger packets without resorting to using a txt file? Thanks.See More

Luis Fraguada replied to Alexander Robinson's discussion Shading mesh faces solid colors....

"If you want to bake it, use the mesh>primitive>mesh coloUrs component to assign the color to the mesh verticies. The result will bake with the color you have applied."

Alexander Robinson replied to Alexander Robinson's discussion Shading mesh faces solid colors....

"Just figured that out! Duh. Though I don't fully understand how Vertex normals work. My next question is now that I'm using Custom Preview to make this work, is there a way to bake this result? I could bake a MeshCol, but…"

David Rutten replied to Alexander Robinson's discussion Shading mesh faces solid colors....

"Meshes can have both Face normals and Vertex normals. If you want to assign unique solid colours to faces, you must unweld the entire mesh, so that the vertices are never shared amongst neighbouring faces. -- David…"

Alexander Robinson replied to Alexander Robinson's discussion Shading mesh faces solid colors....

"I thought the normals where for the center of the mesh faces, not the vertices?? I assume faces are sharing vertices so I guess I would have trouble getting any solid colors on an undulating terrain. I will check out UTOs tool. Separate meshes…"

Luis Fraguada replied to Alexander Robinson's discussion Shading mesh faces solid colors....

"By applying colors to the vertices of a mesh face, the face will get painted with a blend of those colors. So, to give the face a solid color, give the all of the vertices the same color. UTO's mesh edit components can break out a…"
