OpenPlant - Create Area - Programatically set the parameters

Hello,

I need to programatically call Create Area (Under Plant Areas) for several solids.

I found this command MECHADDIN MAKEVOLUME PLANT_AREA and also the underlying APIs Bentley.Building.Mechanical.CreateAreaFromSolid(...)

However a screen appears asking to set several parameters. How can I avoid  the screen and set the params programmatically?
