Take off object ot treeview

Anonymous — Mon, 02 Mar 2020 11:16:12 GMT

I have written a code that select an object and calculate the length, area and volume, then I created a form.

My problem is this: I want to create a form with tree view then select an object and take off that object to a node and assign length, area and volume to its child nodes. The process I mean, is something like Quantification Workbook in Navis. In the following, I have brought my code that calculate area.

Would you mind helping me with this?

Best Regards

Hamid
