Object Types

MaStro works with five types of mesh objects, each identified by a custom property on the mesh data. The type determines which Geometry Nodes modifier is applied and which attributes and panels become available.

Type	Geometry	Description
Mass	Faces	Building footprints
Block	Edges	Perimeter-based buildings
Street	Edges	Road networks
Dimension	Single edge	Annotation anchor
Drawing Mesh	Edges	2D technical drawings

If you already have a mesh you want to use as a MaStro object, use Convert to MaStro Mass or Convert to MaStro Street from the MaStro sidebar panel. The original geometry is preserved; only custom attributes and modifiers are added.
