Some parameters, are not shown in Properties Panel even though it is a valid value for the specified element.
Ex.:
Structural Foundations does not show built in Volume parameter in Properties Panel. So for a rapid value check you need to create a entire schedule, just to see an element Volume value.
Structural Columns does not show built in Length parameter in Properties Panel. So for a rapid value check you need again to create a entire schedule, just to see an element Length value.
Every existing parameter should be available in Properties Panel, and if there are too much of them, allow user to select which ones will appear.
