Synopsis

obj = CYLNDR/point1,[VECT,x,y,z]RADIUS,r,plane1,plane2,point2

Description

Creates a cylinder by specifying a previously defined center point, a radius, and two previously defined planes to limit the sheet display. You may define the axis of the cylinder in terms of a vector. If you do not define a vector, the axis is parallel to the ZC axis.

You must specify a point which is used only if the bounding planes intersect causing two cylinder segments to be

Parameters

Parameter

Description

point1

A previously defined point which lies on the axis.

VECT

The optional minor word VECT indicates that the attitude of the cylinder axis is specified by vector components.

x,y,z

The three component values of a vector which establishes the axis of the cylinder. If omitted the default axis is parallel to the Z axis of the work coordinate system.

RADIUS

Minor word that indicates that the radius of the cylinder is to be specified.

r

A positive value which establishes the cylinder radius.

plane1,plane2

Two existing planes that serve as bounding planes for the cylinder.

point2

A previously defined point which may be needed to determine which portion of the cylinder is created. Although the point is required in this cylinder definition, it is only significant when the existing planes are not parallel and they intersect in the cylinder. This condition causes a partial cylinder to exist on either side of the first plane. The cylinder half which is nearest the point is created.
