Angle
Use the Angle dimension to specify the angle between two edges. The specified angle is applied between the tangent rays at the point of intersection for the two curves underlying the edges.
Add an Angle dimension as follows:
1
Click the Angle () toolbar button.
2
Select two edges, or a vertex that has exactly two adjacent edges.
3
Move the mouse pointer to select one of the four angular sectors to measure, and to adjust the radial position of the circular arrow symbol.
4
Click to place the symbol.
5
In the Settings window for Angle change the value in the Angle text field.
6
Click Build Selected to rebuild the geometry with the new value.
The Settings window for Angle contains the following sections:
•
First Ray: Change the selection for the first edge. The Reverse direction checkbox determines the direction of the edge’s tangent ray at the intersection point.
•
Second Ray: Change the selection for the second edge. The Reverse direction checkbox determines the direction of the edge’s tangent ray at the intersection point.
•
Dimension Value:
-
Adjust the value of the angle. The angle is measured from the first tangent ray to the second tangent ray in the counterclockwise direction.
-
Toggle the Constrain button to switch between using the dimension as a constraining dimension (, default) or measuring dimension (). The value of a measuring dimension is not imposed as a requirement to the drawing. Instead it is updated according to other dimensions and constraints in the geometry sequence. For more information see Measuring Dimensions.
-
Select the Create measuring parameter checkbox to generate a parameter for the dimension. Edit the name displayed in the Parameter name text field. When in sketch visualization mode, the parameter name is displayed in the dimension’s label in the Graphics window. Use dimension parameters in expressions in geometry and other features as described in Dimension Parameters.
•
Help Points: Change the help point coordinates for the two edges. These are used as initial guesses when computing a point of intersection (see Help Points).
