The Properties Panel displays a lot of useful information, but there does not seem to be any way to access the programmatic information.
In this example, the user is trying to extract the value of the Variable associated with a Parametric Solid dynamically... using an expression "this.GetElement().GetDisplayValue("Variation")" This apparently does not work for various reasons.
It would be a big help if there was a tool that the user could use to extract the required expression by right-clicking on the desired field in the Properties Panel. The user would then be able to copy and paste the expression into another tool.
Sort of like Copy Formula in Excel.
