Section 6.3 Creating a Finite Element Model with ANSYS: Preprocessing 227 within the spacing grid. If you have set a spacing of 1.0 and a snap increment of 0.5, then within the X,Y grid you can pick coordinates with 0.5 increments. For example, you cannot pick the coordinates 1.25 or 1.75.

Grid Control Spacing: This number defines the spacing between the grid lines. Minimum: This number is the minimum X-location at which you want the grid to be displayed with respect to the Cartesian coordinate system. Maximum: This number is the maximum X-location at which you want the grid to be displayed with respect to the Cartesian coordinate system. Radius: This number is the outside radius that you want the grid to be displayed with respect to the polar coordinate system. Tolerance: This number is the amount that an entity can be off of the current working plane and still be considered as on the plane. The working plane is always active and, by default, not displayed. To display the working plane, you need to issue the following command:

This feature is useful when you are defining primitives at a location other than the global location. You can move the WP origin by choosing the commands utility menu: WorkPlane Offset WP to > XYZ Locations + You can relocate the working plane by offsetting it from its current location, as shown in Figure 6.17. To do so, issue the command utility menu: WorkPlane Offset WP by Increments ...

Offset buttons: Picking these buttons will cause an immediate offset of your working plane in the direction shown on the buttons. The amount of offset is controlled by the Offset slider and the Snap-Incr value on the WP setting dialog box. Offset Slider: This number controls the amount of offset that occurs with each pick of the offset buttons. If the slider is set to 1, the offset will be one times the Snap-Incr value on the WP setting dialog box. Offset Dialog Input: This feature allows you to input the exact X, Y, and Z offset values for the working plane. For instance, typing 1,2,2 into this field and pressing the Apply or OK buttons will move the working plane one unit in the positive Xdirection and two units each in the positive Yand Z-directions. Location Status: This section displays the current location of the working plane in global Cartesian coordinates. This status is updated each time the working plane is translated.
