x-Distance
Use the x-Distance dimension to set the distance in the x direction between two geometric entities. The x-distance from or to an edge is defined using a stationary point for the point-to-point x-distance along the edge. For example, there are four ways to define the x-distance between two circles.
Add an x-distance dimension as follows:
1
Click the x-Distance () toolbar button.
2
Select two vertices, two curved edges, or a vertex and a curved edge.
3
Click somewhere on the canvas to place the arrow symbol.
4
In the Settings window for x-Distance edit the value in the Distance text field. Note that the distance can also be negative or zero.
5
Click Build Selected to rebuild the geometry with the new distance value.
The Settings window for x-Distance contains the following sections:
•
Geometric Entity Selection: Change the selected entities and their type.
•
Dimension Value:
-
Enter the distance expression in the Distance text field. The distance may be positive, negative, or zero.
-
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 selected entities. The help points are used as the initial guess to determine which x-distance to measure (see Help Points).
