There are some commands and parameters not supported in allplan smartparts.
-There is no section_fill command to define the fill of an object when sectioned.
-You can't change the facecode of an text, 2d or 3d. I can't write in italics, bold, or other styles.
-There is no text_block, or paragraph command which can be found in gdl language
-There is no possibility to import 2d or 3d objects to see their points and coordinates. You can only use the restore function.

It would be nice to be able to make custom list and schedule with parameters from smarparts.
