Add Association Features to Equipment

P-points, Design Points and P-lines can be selected as reference points for Associations. These can be picked in the 3D view when an Association is created.

It can be quite difficult to pick a particular graphical point in a 3D view where many elements are displayed. To make it easier to select reference points or lines to be used in an Association, it is recommended that Design Points are created in Design Templates, and P-points in catalogue items that identify themselves as connection points for Associations.

This can be achieved by creating Design Points or P-points with PURPOSE attribute set to a four character value where the first two characters are chosen by the person defining the point, and the last two characters must be 'FA'. For example, an Equipment may be created with three Association Design Points with PURPOSE attributes set to CLFA for centre-line, BOFA for bottom face and TOFA for top face. Any number of reference points can be created for each element, but it is recommended that only the most commonly used reference points on each type of Equipment or catalogue item are defined in this way, otherwise they will become difficult to identify in a 3D view.
