For example, the following filter selects all circles except the ones with a radius greater than or equal to 1.0:
Object =Circle
**Begin NOT
Circle Radius >= 1.00
**End NOT
- X, Y, Z Parameters
-
Define additional filter parameters depending on the object. For example, if you select Line Start, you can enter the X, Y, and Z coordinate values that you want to filter.
In the filter parameters, you can use relative operators such as < (less than) or > (greater than). For example, the following filter selects all circles with center points greater than or equal to 1,1,0 and radii greater than or equal to 1:
Object = Circle
Circle Center X >= 1.0000 Y >= 1.0000 Z >= 0.0000
Circle Radius >= 1.0000
- Select
-
Displays a dialog box listing all items of the specified type in the drawing. Select the items to filter. For example, if you select the object type Color, Select displays a list of colors to choose for the filter.
- Add to List
-
Adds the current Select Filter property to the filter list. Filter properties that you add to the unnamed filter remain available during the current work session unless you manually delete them.
