Determines the subtype of the current group.
int
tpm_cleangroupsubtype(
ade_id clean_id);
Returns a subtype code or an error code.
| clean_id | The model ID returned by tpm_cleanalloc. |
For an example that shows how you can use the cleanup functions, see tpm_cleanalloc.
| 1 | Degenerate entities (subtype of Erase Short Objects) |
| 2 | Short entities (subtype of Erase Short Objects) |
| 3 | Short segments (subtype of Erase Short Objects) |
| 4 | Vertex is near to segment (subtype of Extend Undershoots) |
| 5 | Vertex is near to vertex (subtype of Extend Undershoots) |
Codes 1 through 3 are subtypes of the short type. Codes 4 and 5 are subtypes of the undershoot type. This function is useful for short and undershoot errors only.
Degenerate Entities A degenerate polyline has only one vertex. This invalid vertex type sometimes results from the drawing cleanup process, and can be removed by further drawing cleanup.
