If the gap between two edges/curves is less than this value, the chain selection will ignore the gap and will select the next segment.

Selects curves in both the positive and negative curve direction. Selects curves in the negative curve direction. Selects curves in the positive curve direction. Type 'edge' before selecting the first segment, or uncheck the 'Curves' selection filter before starting the command to only chain-select surface edges.Ĭontrols the level of continuity required between segments to be selected. Inside a command that accepts chain selection, type chain. Objects that visually seem as though they should be included, but are actually partially outside the boundary, are still included. The testing is done using a bitmap selection mask, which effectively adds an average of half a pixel wide fuzz zone around the selection boundary. NoĪ selection mask bitmap is built from the boundary, and the objects are tested against that mask. If any part of the object is even slightly outside the selection boundary, it will not be included. The testing is done in double-precision floating point in screen space. The selection wire boundary is used as the boundary. Selects objects outside and crossed by selection object or brush stroke. Selects objects completely outside the selection object or brush stroke. Selects objects crossed by the selection object or brush stroke. Selects objects completely covered by the selection object or brush stroke. Your browser does not support the video tag.

Options may not appear at the command prompt.

The command cannot determine which objects are to be used and the pre-selected objects are unselected, and you are prompted to select specific objects again.

The command may proceed, but the result may be unexpected.

The command determines that the objects can be used and proceeds without further prompting.

When objects are pre-selected the possibilities include: Command prompts or options may be slightly different in the two methods.

for polysurface, mesh and SubD vertices, vertexįor commands that require object input, the objects can be selected before or after the command starts.

Sub-object parts can be selected and de-selected using capture tools: SelWindow and SelCrossing, Lasso, SelBrush, SelCircular, SelBoundary, SelVolumeSphere, and SelBox. The Untrim command removes the trimming curve from the surface to get back to the underlying untrimmed rectangular surface.To select a sub-part of an object as input to a command, type The control points display shows the rectangular structure of the surface.

The illustrated surface was created from a circle. If you create a surface from a planar curve, it can be a trimmed surface.

You will see the control points for the whole underlying surface. 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 across a surface, the trim curve itself does not have any real relationship to the control point structure of the surface. You can remove the trimming curve boundaries to make the surface untrimmed with the Untrim command. Every trimmed surface retains information about its underlying surface geometry. This surface may be larger than the trim curves, but you will not see the underlying surface because Rhino does not draw the part of the surface that is outside the trim curves. Trimming curves lie on the underlying surface.

Some Rhino commands work only with untrimmed surfaces and some software does not import trimmed NURBS surfaces. Since it can be important for you to know if a surface is trimmed, the Properties command lists the trimmed or untrimmed state of the surface. The shape of a surface is still defined by a set of control points arranged in a rectangular pattern. Some commands create trimmed surfaces directly. Trimmed surfaces are created with commands that trim or split surfaces with curves and other surfaces. A trimmed surface has two parts: a surface that underlies everything and defines the geometric shape, and trimming curves that mark sections of the underlying surface that are trimmed away. Split and trim objects with other objects.
