Limits Tab

Creating an Obstruction/Exclusion list is not the only way you can set the obstructions. Using the Limits tab you can create an area around items or a region to create an obstruction box. Any element that lies partly or wholly within the limits box is checked. A clash between items that lie partially within the limits box is always reported, even if the point at which the clash occurs lies outside the box.

1. Right-click within the From or To panes but outside of the text fields to display a pop-up menu which allows you to change how the From and To limits are displayed.

   • Format ENU

2. You can set the limits of the obstruction box, enter the values in the text fields or select an option from the Volume drop-down list.

3. To disable (lock) the limits of the obstruction box, select the required East, North, Up check box.

4. Click Clear to set the values defining the corners of the obstruction box to zero.

   Note: A setting of zero in all the fields is by default to include all the elements and primitives in the current MDB.

5. To display the Volume box in the 3D graphical view, select Display check box.
