Construct Revolution

Use it!

(3D only) Used to create a surface or solid of revolution — a complex 3D element that is generated by rotating a profile element (line, line string, arc, ellipse, shape, complex chain, complex shape , or B-spline curve) about an axis of revolution. Surfaces created by the profile element, as it is rotated, are indicated by arcs connecting the keypoints.

Tool Setting	Effect
Type	Can be Surface (not capped) or Solid (capped).
Axis	Sets the direction of the axis of revolution. Points — Direction of axis is defined graphically. AccuDraw can be used to define the drawing plane on which the points are placed. Screen X, Y, or Z — Direction of the axis is set to the screen's X, Y, or Z axis. Drawing X, Y, or Z — Direction of the axis is set to the drawing's, or design file's, X, Y, or Z axis.
Angle	Sets the rotation angle.
Keep Profile	If on, the original profile element is kept in the design.

To construct a solid or surface of revolution

1. Select the Construct Revolution tool.


2. Identify the profile element.


3. Enter a data point.
   see footnote 98
   If Axis is set to Points, this data point defines one point on the axis of revolution. Otherwise, this data point defines the axis of revolution.


4. If Axis is set to Points, enter a second data point to define another point on the axis of revolution.


5. Reset to finish.

   Construct Revolution. AccuDraw used to constrain the axis of rotation, defined by points 2 and 3.

   The completed solid (of revolution).
