You can remove the trim curves and get back to the underlying surface using the UntrimĬommands to remove holes or outside boundaries. You’ll see the control points for the whole underlying surface, which doesn’t necessarily have any connection with the trim curves. You can see this if you select such a trimmed surface and turn its control points on. If you have a trim curve that runs diagonally across a surface, the trim curve itself doesn’t have any real relationship to the control point The trim curves do not define a surface - they only mark which part of the surface is to be considered trimmed away. Only the underlying surface defines the actual geometry of the shape. The underlying surface may be larger than the trim curves, but you won’t see the underlying surface because Rhino doesn’t draw anything for the part of the surface that is outside the trim curves. Those trimming curves exist on the underlying surface. When trimming a surface with a 3-D curve in an angled parallel or a perspective view, the cutting curve is pulled on the surface by closest points.Ī trimmed surface has two parts: a surface that underlies everything that defines the geometric shape, and trimming curves that either trim away the outside portion of the surface or cut holes in its interior. When trimming a surface with a planar curve in an angled parallel or a perspective view like the default Perspective view, the cutting curve is projected on the surface in a direction perpendicular to the curve plane. Parallel view like the default Top, Front, and Right view, the cutting curve is projected on the surface in the view direction. When trimming a surface with a curve in a plan If it is difficult to select the parts to trim off, use the SplitĬommand and then delete the unwanted parts.Ĭommand to remove a trimming boundary from a surface. They only need to appear to intersect in the active viewport. They do not need to intersect in 3-D space. This makes it unnecessary to manually extend lines that do not intersect the objects to trim.Ĭurves are trimmed in relation to the view. When line objects are used as cutting objects, imaginary extensions of the line are used. Select the parts of objects to trim away. Deletes selected portions of an object inside or outside where they are intersected with another object.
