Offset Surface

 History enabled

The OffsetSrf command copies a surface or polysurface so that locations on the copied surface are the same specified distance from the original surface.

Steps

  1. Select a surface or polysurface.
  2. Infinite Plane: Type IP for InfinitePlane options.

  3. Type the offset distance, and press Enter.
Command-line options

Distance

Sets the offset distance.

Corner

Specifies how offset corner continuity handled. These options only apply if the offset direction is to the "outside" as shown in the image.

Sharp

Curves offset to the outside of a corner will be extended to meet at sharp corners with position (G0) continuity.

Round

Curves offset to the outside of a corner will be filled with arc segments with tangent (G1) continuity.

FlipAll

Flips the offset direction of all selected surfaces. Arrows indicate the positive offset direction.

Solid

Makes a closed solid from the input and offset surfaces by lofting a ruled surface between all of the matching edges.

Loose
(Surfaces only)

The control point structure of the offset surface is identical to the original surface.

Note: This option is not available when any of the selected objects is a polysurface.

Tolerance

Sets the tolerance for the offset surface. Type 0 to use the default tolerance.

BothSides

Draws the offset on both sides of the original.

DeleteInput

Yes

Deletes the original geometry.

No

Retains the original geometry.

Shell

The Shell command creates a hollowed out shell from a solid.

Shell only operates on simple, solid, manifold polysurfaces. These surfaces are removed and the remainder is offset inward, using the outer parts of the removed surfaces to join the inner and outer parts.

Steps

  1. Select faces to remove from closed polysurface.
    Leave at least one face unselected.
  2. Press Enter when done
    This step specifies which surfaces will be removed to make the shelled object.

The top surface of the cylinder was selected for removal.
Command-line options

Thickness

Specifies the thickness for the shell.

Troubleshoot shelling

Shell and OffsetSrf for polysurfaces are works in progress. There are several known problem areas:
