Geometric entities

The following is complete list of entities that can be translated into outlines and markers or polylines.
In addition to the entities listed in the table, you can create outlines for any geometry or annotation entity that results in a linear approximation of two points. In this case, a line is created. You can also create outlines for surfaces that are polygonalized.
