No—The sketch does not create any automatic constraints.

Chained - Automatic constraints in the sketch are created in Chained mode.

Stacked - Automatic constraints in the sketch are created in Stacked mode.

FIXTOGETHER - Creates a [[FixTogether]] constraint between the 2D elements of the sketch and the directions of the 2D axes. CATIA's default constraints are also preserved.

FIXTOGETHER_DELCST (Default) - Creates only a [[FixTogether]] constraint between the 2D elements of the sketch and the directions of the 2D axes. CATIA’s default constraints are deleted.

FIXTOAXIS_CHAINED - Creates distance constraints between the first point of the sketch and the H and V directions of the 2D axes, specifically AT THE END, after the automatic constraint "Chained" has been applied to all remaining sketch elements (excluding axes). If the sketch contains no 2D points, the automatic constraint "Chained" is applied to all remaining sketch elements (excluding axes); the origin point of the axes and the H and V directions then serve as reference elements. are the origin of the axes as well as the H and V directions.

FIXTOAXIS_STACKED - All 2D elements of the sketch (excluding axes) are automatically assigned constraints in STACKED mode, using the origin of the sketch axes as a reference. If the sketch does not contain a 2D point, all elements of the sketch (excluding axes) are assigned automatic constraints in STACKED mode, using the origin of the sketch axes and the H and V directions as references.

FORCE cycles through the specified values one by one: If problems occur while updating the sketch, it tries the next value.

Order of the experiments: "STACKED;CHAINED;FIXTOAXIS_CHAINED;FIXTOAXIS_STACKED;FIXTOGETHER_DELCST"

CREATE_AUTO_CST_SKETCH = CHAINED;STACKED; - Multiple options, separated by ";", are allowed. As soon as a setting is successful, it is used and the search is terminated.

Further example:

CREATE_AUTO_CST_SKETCH = FIXTOAXIS_CHAINED;CHAINED;STACKED;...
