### Separate Naked Vertices5 Replies

Hi everyone,There is a polygon and it was meshed. And the naked vertices were found from the mesh.How can i extract vertices that are along the straight sides of polygon from the naked vertices…Continue

### Reordering branches by sorting the length of points connection7 Replies

Hi,Based on the subject,i am confusing how to reorder the branches {0;0}{0;1}{0;2}{0;3}{0;4}--->one groupand {1;0}{1;1}{1;2}{1;3}{1;4}--->another groupby sorting the values which were…Continue

### Testing if points on a line

Hi everyone:There is a problem about finding the points on mesh naked edges.I meshed surfaces and wanted to find the points on the one of the lines.When I used the "curve closest point," I could not…Continue

### Extract a polyhedron from a mesh or point cloud17 Replies

Hi I got a mesh from image process, and want to extract the shape of the mesh.In addition, I converted the mesh into the point cloud,and tried to find some plane to bulid the polyhedron. But the…Continue

"Your problem has nothing to do with "Curve Closest Point". It's just a matter of data matching."

"Hi, Thanks a lot. This way can deal what i want. But sometimes, I am confused with using the grasshopper component like "Curve Closest Point", if i want to find each mesh's separated naked points.(Neglect shared…"

"In this case, there are some shared edges and duplicated naked points. Do you want something like this?"

"Hi Kim, Thank you for your quick reply! I appreciate it. I have another question... How to deal the component "Curve Closest Point", when the polygon is more than one? If i want to separate all the naked vertices along…"

### Separate Naked Vertices

Hi everyone,There is a polygon and it was meshed. And the naked vertices were found from the mesh.How can i extract vertices that are along the straight sides of polygon from the naked vertices ??Thanks for help!See More

"Why don't you use "Match tree"?"

"Hi, That's totally i want. Thanks for the awesome logic!!!! Moreover, How to change the "tree branch" renumber output{0}{1}{2}{3}{4} {5}{6}{7}{8}{9} to {0;0}{0;1}{0;2}{0;3}{0;4}{1;0}{1;1}{1;2}{1;3}{1;4}??"

"Like this?"

"On the "K" output of the SORT component: Right click it and select "Graft". (I think that's what you're after?)"

"Hi, That's right! What i want to do is reordering the branches from{0;0}{0;1}{0;2}{0;3}{0;4} {1;0}{1;1}{1;2}{1;3}{1;4} to {0;2}{0;4}{0;1}{0;0}{0;3} {1;1}{1;4}{1;3}{1;0}{1;2} that follows the order of sorted lines length ."

"I don't understand what you mean but according to your screen grab, I guess you may already have grouped point list before your partition list component."

### Reordering branches by sorting the length of points connection

Hi,Based on the subject,i am confusing how to reorder the branches {0;0}{0;1}{0;2}{0;3}{0;4}--->one groupand {1;0}{1;1}{1;2}{1;3}{1;4}--->another groupby sorting the values which were calculated with connected points length in each branch.Thanks for any idea!!See More

### Test if points on a line

Hi everyone:There is a problem about finding the points on mesh naked edges.I meshed surfaces and wanted to find the points on the one of the lines.When I used the "curve closest point," I could not match the data I wanted like the pic below.How can I use the said component to find the distances between the points and each line?Many…See More
