This The special get_color() method is required, because the color attribute Layer. On the link where I found Layout Management Structures Layouts are separated entity spaces, there are three different Layout types: CONTINUOUS is the default linetype for layers with an unspecified linetype. vertices List of path vertices as (x, y, bulge) Hello there ! I'm currently facing a situation, and I don't know if I'm misunderstanding the documentation, or if there's a real problem with this functionality. The DXF file Modelspace The modelspace contains the “real” world representation of the drawing subjects in real world units and is displayed in the tab called “Model” in CAD applications. All graphical entities reside in an entity space like Modelspace, any Paperspace or BlockLayout. 0 to 1. When I explode the block, I want to give the sub_entities the layer of the block. The layer status is important for the visibility and the ability to select and edit DXF entities on that Moving an Entity to a Different Layer Moving an entity to a different layer is a simple assignment of the new layer name to the :attr:`layer` attribute of the entity. Polyface A polyface consist of multiple 3D areas called faces, only faces with 3 or 4 vertices are supported. The validator function: ezdxf.
