"But David, depending on how I slide the numbers on red rectangle linked to Amplitude (A), the holes turns on surfaces how could I solve this?? Might you take a look? It will need the Rabbit plugin"

"thats not all - to make it "really" one object, you need to weld after joining (weld command). "

"ctrl + j does the trick. Or "join" in the command line."

What is the Rhino3d command as Mesh Join in Grasshopper??

Hi,What is the Rhino3d command to make a single mesh from set of meshes after meshed polysurface objects? (like a 'Mesh Join' in grasshopper?)Thanks!!See More

Loosing planarity when curve is transformed?

Hi, all, Just curious why the curve is loosing the planarity when it is transformed. 1. Draw the planar curve on global plane.2. duplicate the curve, and transform plane to plane into another 100 number of 3d position. (due to the different orient of plane, it is moved and rotated) Now, some of the curve isn't any more planar. (but deviation from curve plane is really tiny) Which step is causing to loose planarity? Is it due to the duplicate tolerance? or transform process? Thanks!See More
