autocad_entity: autocad_viewport
Features with autocad_entity set to autocad_viewport are read from drawing files as rectangular entities that represent viewport entities from a paper space. They will have a number of attributes that define how the viewport will appear in an AutoCAD application.
If the reader parameter Read Model Space Entities Through Viewport is selected, a representation of model space entities will be read as they appear through the viewport. These features will have the attribute autocad_viewport_handle set to the handle of the viewport they were read through. The resulting features are only a representation of model space entities and will be ignored by the writer. Writing of these features can be forced by removing the autocad_viewport_handle attribute.
