Feature Context

Menus

 Common tools:

• Disable: temporarily disables a feature and skips its constraining.

• Dissolve: removes a feature but keep its geometry. Design intent associated with the geometry of a dissolved feature will be removed.

• Delete: same as the SmDelete command. Removes features from the Mechanical browser and deletes the corresponding geometry inthe model.

• Zoom to: zooms to the selected feature.

• Collapse all: collapses the main component and all components and subcomponents.

• Expand all: expands the main component and all components and subcomponents.

Flange feature

Right click a flange feature: 

• Flip: swaps the sides of a selected flange so that the reference face is on the opposite geometric side of the flange. This operation shifts the flange by its thickness, in order preserve the position of reference face.

Right click on a bend feature: 

• Switch to junction: switches to a junction feature type with a gap between adjacent flanges.
• Switch to lofted bend: switches to a lofted bend feature.

Right click on a lofted bend feature: 

• Switch to junction: switches to a junction feature type with a gap between adjacent flanges.
• Switch to bend: switches to bend feature.

Right click on a wrong bend feature: 

• Repair feature: repairs a wrong bend feature by creating a bend feature with proper geometry, if possible.

Right click on bend relief feature: 

• Switch to smooth, round or rip: switches a bend relief to the selected feature type.

Right click on corner relief feature: 

• Switch to V-type or circular: switches a corner relief feature to the selected feature type.

Right click on junction feature: 

• Switch to bend: switches to a bend feature.
• Switch type of the feature: switches the alignment mode between symmetrical and aligned with one of the flanges.

Right click on miter feature: 

Right click on form feature: 

• Select same feature: selects all form features of the same type in the model.
• Explode to flanges and bends: explodes a form feature into a set of flanges and bends, if possible.
• Repair feature: recalculates the insertion point of a form feature.
• Replace...: displays the Open dialog box in order to choose a replacement form feature.

Common property:

• Name: the name of the selected sheet metal feature. Optionally type a name for the feature. The default name of a feature is the feature type plus an increment, e.g. Flange_1, Flange_2, ...

Flange feature

Click a flange feature:

• Thickness: current thickness. The value is read-only; it equals the sheet metal component thickness property.

Bend feature

Click a bend feature:

• Angle: current angle of the bend feature; can be changed by the SmFlangeRotate command.
• Radius: current bend radius.
• Radius type:
  • Thickness ratio: ratio of thickness multiplied by a coefficient
  • Absolute value: the global value (main sheet metal component properties).

Click a bend relief feature: 

• Relief type: current relief type; either rectangular, smooth, round or rip
• Width: width of the cut near the bend; either global, thickness ratio or absolute.

Click a corner relief feature:

• Relief type: current relief type; either rectangular 2 bends, rectangular, v-type or circular
• Width: width of the cut near corner.; either global, thickness ratio or absolute.

Click a junction feature:

• Junction gap: gap between two adjacent flanges. 
• Junction gap type: either global, thickness ratio or absolute.
• Connection type: controls the relative position of adjacent flanges; either symmetric or adjacent to one of the flanges.
• Junction alignment: controls the position of the faces of a junction feature; either global, enabled (aligned with the corresponding corner relief feature faces) or disabled

Click a miter feature:

• Miter gap: gap between the side faces of the miter.
• Type: either thickness ratio or absolute.
