Warning after NewFamilyInstance

[AndrewButenko]

Hello! I  have warning after creation NewFamilyInstance

"Mass contains only mesh geometry, which can’t be used to compute Mass Floors, volume, or surface area."

document.Create.NewFamilyInstance(New XYZ(0, 0, 0), fs, aw, [Structure].StructuralType.UnknownFraming)

fs -family symbol

aw-view

But when I create instance from same family in Revit (not programmatically) then I have not the warning.

What can I do for the warning not show?
