The MergeSrf command will not smooth non-fully multiple interior knots.Ĭombines two co-planar surfaces in a polysurface into one surface.Ĭombines all co-planar polysurface faces that share at least one edge with the selected surface into one surface. You’ll see that even though the trimming edges of the two surfaces connect, their underlying surfaces do not line up with one another. On the two trimmed surfaces that you want to merge, this process will become more clear. If the control points do not line up on two trimmed surfaces, the surfaces cannot merge, as control points merge together to make a single surface out of two individual surfaces. It is the underlying surface that controls the geometry, and that is what the MergSrf command needs to join surfaces to make one large surface out of smaller surfaces.įor two trimmed surfaces, you will see that even though the surfaces can touch up to one another nicely at their trims, their control points do not line up. Trimming curves tell Rhino that some parts of the surface are supposed to be holes or are supposed to be cut out. Once you have trimmed surfaces, however, you have to approach things differently.Ī trimmed surface has an underlying untrimmed surface that defines the geometry of the shape. Use the MergeSrf command to make them into a single surface. Generally, you can only use the MergeSrf command when you have created untrimmed surfaces by lofting or sweeping and the surfaces share adjacent edges. If the merged surface is closed, use the MakePeriodicĬommand to make an even smoother, editable surface. Surfaces can merge only if the shared edge on both surfaces run exactly along u- or v- directionĪnd the surfaces share both edge endpoints. The seam where the two surfaces meet smooths out, which is useful for modeling half of an object, mirroring it, and then merging the surfaces together to eliminate the kink Untrimmed surfaces that share an edge can merge into a single surface. Acceptable values are between 0 (sharp) and 1 (smooth).

Zero or a value less than the absolute tolerance is not acceptable.ĭefines the roundness (smoothness, dullness, bluntness, non-sharpness) of the merge. The Tolerance setting defaults to the Rhino global absolute tolerance. Surface edges must be within this tolerance for the two surfaces to merge. This makes the surface behave better for control point editing, but may alter the shape of both surfaces. Combines two surfaces into one surface at untrimmed edges.īoth surfaces must be untrimmed and share an edge.
