- Bend: extends a wall from a side face of the metal sheet. Properties can be edited in the Data tab:
- Dataangle: Bend angle.
- Dataextend1: Extends the wall on the left side.
- Dataextend2: Extends the wall on the right side.
- Datagap1: Gap from the left side.
- Datagap2: Gap from the right side.
- Datainvert: Invert bend direction.
- Datalength: Length of the wall.
- Datamiterangle1: Bend miter angle on the left side.
- Datamiterangle2: Bend miter angle on the right side.
- Dataradius: Bend radius.
- Datarelief Type: Rectangle or Round. Enabled only when a gap value is set.
- Datareliefd: Relief depth. Enabled only when a gap value is set.
- Datareliefw: Relief width. Enabled only when a gap value is set.
- Datakfactor: K factor (also known as neutral factor) for the bend. Used to calculate bend allowance when unfolding.
- Dataunfold: False (default) or True. If true, unfolds the bend.
- Extrude: extends a face along normal. Properties can be edited in the Data tab:
- Datagap1: Gap from the left side.
- Datagap2: Gap from the right side.
- Datalength: Length of the wall.
- Unfold: flattens folded sheet metal object and generates a solid and a sketch. The Unfold objects are not parametrically linked to the model; if edits are made to the model, the Unfold operation needs to be redone.
