obj list = SUBTRA/obj,WITH,obj list[,CNT,c][,IFERR,label:]

描述

Allows you to subtract solids from solids, sheet bodies from sheet bodies, and sheet bodies from solids, as long as the sheet body cuts the solid completely. The resulting body is parametric only if a single body results. When multiple bodies result, they are not parametric.

参数

参数

描述

obj

The target solid.

WITH

Minor word indicates that the following list of objects is to be subtracted from the target solid.

obj list1

A list of tool solids you wish to subtract from the target solid. Maximum number allowed in list is 1000.

CNT

Optional minor word indicating that a count of solid objects is to be returned.

c

Variable which returns the number of solid objects.

IFERR, label:

Specifies a label to which program execution jumps if an error occurs. Possible errors include: non-manifold body or boundary; maximum number of tool objects exceeded; illegal object type in list, etc.
