创建偏移体

Synopsis

obj = OFFSRF/obj,distance[,TOLER,edge curve tolerance]

Description

Creates an offset body from a previously defined base face at a specified distance. When creating the offset body, the system also generates edge curves. You may specify an edge curve tolerance to control how accurately the edge curves lie on the body.

Parameters

Parameter

Description

obj

The existing base face from which the offset body is offset.

distance

The distance from the base face along the face normals, at which the new offset body is created. The distance may be positive or negative but not zero.

TOLER

Minor word indicating that a tolerance is to be specified. If none is specified, the default is the value set in the Unigraphics option Preferences->Modeling. You can also read and set this tolerance using the GPA &DISTOL.

edge curve tolerance

Controls how accurately the edge curve lies on the body. The smaller the tolerance value, the better the edge curve lies on the body.
