PD_INFO_ELEMENT function
+------------+
| |
-->(PD_INFO_ELEMENT)--v--|id_pnt|--^----->
PD_INFO_ELEMENT is used to query how PD_RESOLVE determined the position and size of the element identified by id_pnt during the last call to PD_RESOLVE in the current session. All constraints that were used in the determination will have their icons displayed and all geometry on which those constraints rely will have their geometry highlighted as well.
Using this command on an element which was not solved for in the last call will produce no icons or highlights.
If the constraints have been edited since the last call to PD_RESOLVE then the information returned could be misleading.
