Radial Dimension Parameters
Project Editor - Tools => Add Dimension Parameter => Add Radial
A radial parameter defines a dimension using an anchor point, a reference point and an adjustable point set. The nominal value of the parameter is defined by the distance between the anchor point and the reference point. When the dimension is varied, each point moves along a line extending from the anchor point through it’s original position. Setting up a radial parameter is identical to setting up an anchored parameter. When defining your parameter, you perform the following steps:
1. Select Tools => Add Dimension Parameter => Add Radial from the project editor menu.
The cursor changes to indicate that you are adding an radial dimension parameter.
2. Click on the point on a polygon which you want to use as the anchor for the dimension parameter.
This is the fixed starting point for the dimension parameter. Its selection is indicated by an open square
3. Click on the point on a polygon which you want to use as the reference point for the dimension parameter.
The reference is the first point in the adjustable point set. The distance from the anchor point to the reference point is the nominal value of the dimension parameter. When the value of the dimension parameter is changed, the anchor retains the same position, but the reference point moves to a new position.
4. Select any additional points in your circuit you wish to move with the reference point.
You select the rest of the points in the adjustable point set by clicking on individual points or by lassoing a set of points with the mouse. Selected points are highlighted with black dots. As the value of the dimension parameter is varied, the reference point, as well as the rest of the adjustable point set, is moved accordingly.
Note that the dimension parameter is always defined as the absolute distance between the anchor and the reference point.
5. Once all the desired points have been selected for the adjustable point set, hit return.
The Parameters Properties dialog box appears on your display. The nominal value entry box is disabled and displays the nominal value of the parameter just assigned. The Variable Name text entry box is empty and enabled.
6. Enter the desired variable name in the Name text entry box, then click on the OK button.
The variable name appears on your display and moves with the mouse cursor.
NOTE: Names of variables are case sensitive.
7. Move the mouse until the name of the variable is in the desired location, then click the left mouse button.
The variable name appears with an arrow indicating that this is a radial dimension parameter.
Note that the status bar displays a message detailing each step as you are adding the dimension parameter as well as pop-up hints.
Tip: Double clicking on a dimension parameter in your circuit opens up the Parameters Properties dialog box in which you can easily can the name, or nominal value.
