Description

Analyzes a solid defined by rotating a list of objects about the XC or YC axis. The objects must be boundary objects to form a main boundary and any desired sub-boundaries (holes, etc.). You may define the objects by specifying a bounded plane.

Parameters

Parameter	Description
VOLREV	Minor word which indicates that an analysis of the volume formed by revolving a two dimensional figure about either the X or the Y axis of the work coordinate system is desired.
XAXIS,YAXIS	Minor word that indicates the axis about which the volume of revolution is to be generated.
d	The density per unit volume for the material required.
TOLER	Minor word which indicates that the following parameter is a tolerance value.
t	The chordal tolerance which is used to generate the boundary for the volume of revolution.
obj list	The object list must consist of a bounded plane or a main boundary followed by any sub-boundaries which may be required. NOTE: None of the objects in the boundaries may cross the axis of rotation; however, the axis of rotation may form part of the boundary. The direction for sub-boundaries, which must be opposite of the direction of the main boundary, is established by the sequence of objects in the boundary statement.
INCHES,MMETER,CMETER,METER	Minor words which determine whether the unit value for the analysis is inches, millimeters, centimeters, or meters respectively.
variable list	A numeric array that is assigned values as shown in the following table.
