Select Floor Slabs and Height Difference between them to place formwork family

Hello,

im a little new to C#, I was trying to look for a way where the Plug-In lets me select a top floor slab and then the bottom floor slab, so that I can subtract the parameters from both and get the height difference. The issue is I do not understand how to tell the code to let me select the second floor slab. Is there a link which describes something similar?

I have been successful in selecting the first floor slab and display the height of its bottom surface. To calculate the height difference I need to be able to select the bottom floor slab and get its top height, then I can subtract the two. But this seems to be a challenge. Any similar link or code, which does this?

Hi @d.ahmed.hb ,

Are you looking for this?

//Lets you to Select first floor Reference r1 = uidoc.Selection.PickObject(ObjectType.Element); Floor firstFloor = doc.GetElement(r1.ElementId) as Floor; Parameter firstFloorParameter = firstFloor.get_Parameter() (or) firstFloor.LookupParameter(""); double firstFloorHeight = firstFloorParameter.AsDouble(); //Lets you to Select second floor Reference r2 = uidoc.Selection.PickObject(ObjectType.Element); Floor secondFloor = doc.GetElement(r2.ElementId) as Floor; Parameter secondFloorParameter = secondFloor.get_Parameter() (or) secondFloor.LookupParameter(""); double secondFloorHeight = secondFloorParameter.AsDouble();

Gentlemen,
Does this work with sloping floors (top or bottom or both)?
