描述

Allows you to create a parametric solid tube or cable along a path of curves. The path of curves must form an open boundary.

参数

Parameter

Description

obj list

A list of curves which form the path for defining the tube or cable. Be careful when you define the path because you are not allowed to create a self intersecting solid. All Unigraphics curves are valid. The curves must form a continuous chain, and may not be a closed boundary.

NOTE: Best behavior is achieved when adjoining curves have tangent slopes at their point of intersection.

DIAMTR

Minor word indicating that the following value specifies the outer diameter of the tube or cable.

d1

The outer diameter of the tube or cable.

d2

Optional value for the inner diameter of the tube or cable. If this is not specified, the inner diameter defaults to zero.

TOLER

Optional minor word indicating that the following value specifies the curve approximation tolerance. 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.

t

The curve approximation tolerance. If the path of curves contains curves other than lines and arcs, they are approximated by a series of lines and arcs. This tolerance controls how accurately the curves are approximated. The smaller the value, the more approximating segments are used.

IFERR,label:

Specifies a label to which program execution jumps if an error occurs. Possible errors include self intersecting solid, negative tolerance, non-continuous curve path.
