Other Selection Methods

Other Selection Methods

In many contexts where an individual item (as opposed to a list) is required PRIMER will use "popup" menus to select things.

For example the creation of retractor elements requires, among other things, the definition of a central node and a seatbelt element. As shown here you can type a label into the relevant text entry box, or use the right mouse button to invoke a selection menu which will have the standard options: These standard options allow you to (screen-) PICK the item directly, or SELECT it from a standard selection as described here.

Picking and sketching will only be available for viewable items (for example you can't pick a loadcurve).

The CREATE and EDIT functions will only be available for those items which PRIMER currently has the ability to create/edit.

Given a little thought these concepts are straightforward, but you need to take a little care. For example selecting a PART is not the same as selecting all the ELEMENTS in that part:

• Deleting by ELEMENT will delete the elements but leave their PART definition intact (if redundant).

• Deleting by PART will delete both elements and the PART definition itself.

(The interaction of hierarchies and deletion is explained further under REMOVE.
