OFFSET terminate action

OFFSET offsets the position of one or more faces, or the position of recognized features by one, specified distance.

A flat face after being offset would remain parallel to its original face, with its position modified from its original position by the input distance value or length.

Options

The following options are available to define the offset operation:

:FACES - specifies the faces you want to offset.
:BOSS_POCKET - specifies the bosses or pockets you want to offset.
:BLEND_AUTO - finds all neighbour blends/chamfers automatically. These blends/chamfers will be suppressed before the offset, and resumed after the offset operations is performed. This switches off :keep_blend.
:KEEP_BLEND - the user selects the blends/chamfers to be recreated. This switchtes off :blend_auto.
:KEEP_TANGENT - enables/disables the automatic recognition of tangent neighbour faces. With :keep_tangent :yes the system tries to keep the tangential transition to the neighbour faces in the offset operation.
:FIX_EDGES - holds the selected edges on tangential neighbour faces fix in space. This option can only be used when :keep_tangent is on.
:UNFIX_EDGES - releases formerly fixed edges. This option can only be used when :keep_tangent is on.
:UNFIX_FACES - converts a secondary tangent face (which is kept fixed in space) to a primary tangent face (which is transformable). This option can only be used when :keep_tangent is on.
:DISTANCE - specifies the distance through which the face or feature is to be offset.
:CHECK - activates the automatic body checking operation.
:NOCHECK - disables the automatic body checking operation.
:PREVIEW - does a preview of the operation and colors all changed faces.
:DO_IT - accepts the defined faces and offset distance, and performs the operation.

When to use

Use this command to offset a single face, modify the wall thickness of some or all walls of a shelled body.

Offset a recognized feature in one direction by a specified distance.

Example

The following parameter sequence offsets a specified face.
