Measuring and Dimensioning
Angular Dimension tool
The angular dimension tool allows the user to create and edit angular dimensions. An
angular dimension indicates an angle in the drawing. The creation procedure of an
angular dimension with this tool depends on the state of the Set Vertex button, which
is found on the Dimension property bar.
(Vertex - the point at which the sides of an angle intersect the point of a triangle
opposite and farthest away from its base.)
If the Set Vertex button is down, then:
To use the Angular Dimension tool
1 Left click the mouse once, setting the vertex of the angle.
2 Left click a second time, setting the origin of the first extension line.
3 Left click a third time, setting the origin of the second extension line.
4 Left click a fourth and final time, setting the position of the dimension line.
If the Set Vertex button is up, then:
1 The first mouse click must be on a line point, curve point, or image edge point, so that
the tangent at the point can be used to set the slope of the first extension line. The
point sets the origin of the first extension line.
2 Left click a second time, doing the same as above to establish the slope and origin of
the second extension line.
3 Left click a third time, setting the position of the dimension line.
4 If a required slope has not been specified by a mouse click, then a prompt appears to
type in an angle or it cancels the operation.
