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 catalog items that identify themselves as connection points for Associations.

The user can create Design Points or P-points with the 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 center-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 catalog item are defined in this way, otherwise they become difficult to identify in a 3D view.
