Check the P-point Position of a Primitive

You will need to know how to check that it is correct when you have built it. You can check this co-ordinate by checking the position of the appropriate P-point, which is associated with each of the edges. Those for a box are reproduced as follows for convenience.

The P-points are in the center of each face apart from the origin of the box, P0, which is in the center of the box.

1. To check the box P-points, use the Query > General menu.

2. Select the P-points option to check each of the individual points in turn.

   By default, all querying will be done relative to the equipment, but you can select world, site or zone options as well. Any mistakes made need to be corrected. The errors you are likely to have made will only be in the areas of position, size or orientation, so you should try to use the appropriate menus to make corrections.
