Picking the points only establishes the extrusion distance. Make a line and extrude it to a flat surface to split arms Note: You will have to: command: Cap open surfaces after splitting if you use NURBS to make a watertight polysurface if working with mesh: command: MeshBooleanSplit automatically makes watertight trims. I start with a single 2D curve, then extrude a small rectangle along it to make one straight rib.

Feel free to also send the model into tech mcneel. In the meantime, scale with the Scale2D command. I'll file this as a bug now to see if we can account for this case. Coincident surfaces are not always an issue with Booleans but in this case I think the area where the inner cylinder wall diverges from the tear drop shape is the reason for the failure. If you scale the interior cylinder very very slightly e. Views: BooleanUnion will work here but the perfectly coincident cylindrical surfaces are causing it to fail. Meshes are never created and that message will stay there until it is replaced by a message stating that auto save has successfully completed. If I explode the polysurfaces and try to join them, the command line shows "Creating meshes Press Esc to cancel". How do I join these 2 closed polysurfaces? Image attached. My first designs are simply the equivalent of wires and bezel cups. I'm stuck when it comes to joining closed polysurfaces.

I am brand new to CAD software and Rhino 5. That option is only available if you do not preselect the meshes before starting the command.Greetings all. This implies two things: If the original mesh quad face was defined by 4 coplanar points, all the edge lines are in the same plane, and the resulting NURBS surface will be planar. Thus, the defining edges of the NURBS surface in this case are the same as the lines representing the Mesh face's edges. There are even a couple of plug-ins available to add this capacity to Rhino but they are not free. They range from moderately expensive to very expensive. There are also several specialized reverse engineering software packages to partially automate this process.

There is much info available on the subject of reverse engineering and its difficulties here is one article on how to attempt this with Rhino tools. If the surface has been cut with a curve that is other than its natural edge, it is called trimmed. It is a very complex subject and will not be discussed in detail in this article. Quad facets may be planar, but they are not guaranteed to be so, as 4 non-coplanar points in space will describe a warped area. Only triangle meshes are guaranteed to have all planar facets. Important note: Although mesh facets are often believed to be always planar, this is an incorrect assumption.

A series of facets join together to make a mesh object. The points at the corners of the facets are called vertices. Individual mesh facets in Rhino can have either 3 sides triangles or 4 sides quads. To repeat, meshes are faceted representations of 2D and 3D surfaces. There is no pixelization or granularity as with a mesh. They are capable of representing complex free form surfaces that are inherently smooth, and they keep their smooth shape when editing. NURBS surfaces are mathematical representations of curves and surfaces.
Although both can represent a 3D object as a computer model, they do it in completely different ways.Ī mesh represents 3D surfaces as a series of discreet facets, much as pixels represent an image with a series of colored points. To fully understand what this operation does, familiarize yourself with some of the basics of 3D constructive geometry as well as characteristics of both mesh and NURBS objects.
