Introduction

This tool revolves a selected sketch or 2D object about a given axis.

For all the following explanations of this command the example sketch below will be used:

Example sketch: A complex sketch with many constraints. Sketch is oriented in the x-y plane, with x being the horizontal axis, and y being the vertical axis (shown in image as the two blue lines). Other important things to note about this sketch is that it are mirrored about the y axis and that the base of it is coincident with the x axis.

Options

Base

Angle

This controls the angle through which the revolution is to be formed e.g. 360degrees would be a full, contiguous revolution.

Axis

This option specifies the axis about which the sketch is to be revolved. Setting the value of 1.00 in one of the x, y or z boxes will tell the tool to revolve the sketch about that axis. This option only recognizes values of 0.00 or 1.00, and only one of the three axis boxes may posses a value of 1.00 (think of it as an on/off switch.) The three pictue4s below show the example sketch revolved about the x, y, and z axis respectively:

Placement

Angle

The Angle argument specifies how far the object is to be turned. The coordinates move the origin of the axis of revolving, relative to the origin of the coordinate system. If you select a user defined axis, the numbers define the direction of the revolving axis with respect to the coordinate system: If the Z coordinate is 0 and the Y and X coordinate are non-zero, then the axis will lie in the X-Y-plane. Its angle is such that its tangent is the ratio of the given X and Y coordinates.

Examples

Example revolution 1: In this image the angle has been set to 70degrees. The sketch is the face not shown in the image (i.e. the 'back' face).
Example revolution 2: In this image the angle is 70degrees, revolution is about the z-axis and there is a y-offset of 100mm.
