Each surface offsets as an individual object. The OffsetSrf command does not maintain the overall structure of the starting polysurface in the offsets. It will return six separate surfaces with gaps between the edges. For example, offsetting the six sides of a box will not result in a larger closed box. When offsetting surfaces are joined that are part of a polysurface, there is no guarantee that the offset surfaces will also join into another polysurface. Free-form surfaces are offset to within the value of the Tolerance option. When a plane, torus, sphere, open cylinder, or open cone surface is offset, the resulting surface is exact. Positive values offset in the direction the arrows. Type 0 to use the default tolerance.ĭraws the offset on both sides of the original. Sets the tolerance for the offset surface. The resulting surface point structure is identical to the original surface. Makes a closed solid from the input and offset surfaces by lofting a ruled surface between all of the matching edges. Arrows indicate the positive offset direction. Maintains the sharp corner when the original surface has a sharp corner.įlips the offset direction of all selected surfaces. Type the offset distance, and press Enter.Ĭreates a fillet at sharp corners in the original surface. The OffsetSrf command copies a surface or polysurface so that locations on the copied surface are the same specified distance from the original surface. OffsetSrf with sharp corners explodes and leaves gaps OK, let’s try the OffsetMesh route Mesh the object Unable to get all simple 1 triangle faces, they are arbitrarily split OffsetMesh the result. OffsetSrf with rounded corners succeeds, but the client wants sharp corners. In the attached the “client” wants to offset the simple polysurface object to the outside 0.1 units, solid.Here how we can extract one of the surfaces from such objects – there are different reason why we may need it. For example, a cylinder is a polysurface: it contains the top, the bottom (both circular surfaces) and then the “rolled” sides. Polysurface is an object that contains more than one joined surface. I’ve sucessfully imported similar, but more complex surfaces from the same Rhino file into Revit. Only after significantly splitting or deleting control points down to a small portion can I get this object to import. Adjust the geometry in the file and try the import process again’). This Result can be caused by various issues with the source file.Offsetsrf Failure On Complex Polysurface Work.Offsetsrf Failure On Complex Polysurface In Rhino.Name ID Description Type Surface: S: Surface to offset: Surface: Distance: D: Distance to offset.
