描述

obj list

A series of curves to be revolved around the specified axis. If the specified curves are not closed, the system creates a solid sheet. A closed loop of curves creates a solid. The curves do not have to be coplanar. The maximum number of objects allowed is 514.

When attempting to create a hole, first specify the objects that make up the hole, then specify the remaining peripheral objects.

NOTE: In the case of a closed loop of curves, if the curves are not coplanar, then the system attempts to attach a sheet body to the loop. If no body can be attached, then the extrusion fails. Planar, spherical, conical, cylindrical, and toroidal bodies can be attached.

ORIGIN

Minor word indicating that the following values specify the origin for the axis of rotation.

xc,yc,zc

Work coordinates specifying the origin of the solid.

ATANGL

Minor word indicating that the following value specifies the angle of rotation.

a

The angle of rotation for the solid. The positive direction is determined by the right hand rule for rotation. Align the thumb of your right hand with the displayed vector. The direction in which your fingers curl is the direction of positive rotation.

AXIS

Minor word indicating that the following values specify the axis of rotation.

i,j,k

Specifies a vector which defines the axis of rotation. The system defines the axis as parallel to the specified vector, passing through the origin. If no axis is specified, the YC axis is used.

IFERR,label:

Specifies a label to which program execution jumps if an error occurs. Possible errors include: an invalidly specified axis or origin; parameter values not within correct ranges; number of objects exceeds maximum allowed; invalid object types listed; the geometry fails to pass checks while subdividing a face; the system is unable to find a body while attaching a sheet to a face; etc.
