Setting a Sphere Spatial Rule
Spatial rules use volumetric information to determine what components to display or hide in a CAD document structure. Spatial rules can be used in conjunction with other rules and filters to reduce the structure display to only those portions that are relevant to a specific design task.
Use the following steps to define a sphere spatial rule:
1. Select the spatial rule icon
on the
Visualization tab, then select
Set Sphere Spatial Rule.
The Sphere Spatial Rule Coordinates window opens. By default, the radius from the X, Y, and Z values for the sphere’s center encompasses the entire structure.
2. Enter the X, Y, and Z coordinate values for the center point of the sphere in the Center Coordinates input fields. You can enter zero as well as positive and negative real numbers. All three coordinate values are required.
| Spatial filter dimensions can be manipulated graphically using the spatial filter volume representation in the Visualization tab. • Click and drag the coordinate system gnomon by its origin or one of the axis to move the entire filter volume. • Click and drag a face of the box or sphere to increase or decrease the filter volume. The spatial filter coordinates change as you modify the filter volume. |
3. Enter a positive real number for the radius of the sphere in the Distance from Center input field.
4. By default, parts that are partially within the spherical volume are included in the structure. Select Remove items that are partially outside the bounding sphere to include only those parts that are completely within the sphere.
5. Click OK.
The rule is applied to the part structure and the Sphere Spatial Rule Coordinates window is dismissed.
