SmRepair

Sheet Metal Sheet Metal Sheet Metal

Restores the 3D solid model of a sheet metal part by thickening one of its sides: all thickness faces become perpendicular to flange faces.

Fixes problems specific to parts with lofted bend features: merges adjacent bends and provides tangential connection with flanges.

Accessing the Command

command bar: smrepair

menu bar: Sheet Metal | Repair Sheet Metal

toolbar: Sheet Metal |

ribbon: Sheet Metal | Heal |

: smrepair

Prompts you in the command bar:

Select a face to repair: (Select a face.)

Scan for lost details (may take time)? [Yes/No/Settings] <No>: (Press Enter or choose an option.)

A body with thickness faces perpendicular to the selected face and without adjacent lofted bends will be created.

Notice that the size and position of the opening on the selected face is preserved; the size and position of the opening in the opposite face is adjusted.

Description

Scan for lost details

Searches and retains as separated bodies model parts which remained after repairing.

Prompts you:

Enter scan tolerance <0.01>: Type a value or press enter to accept the default value.

Scan tolerance: The fraction of the initial model volume, which will be ignored, only larger bodies will be retained. E.g. if the scan tolerance = 0.25, only parts with a volume that is larger than 25% of the initial body will be retained.

From left to right:

Initial model with unrecognized form feature
Model after SmRepair without scanning for lost details: the circular feature is removed.
Model after SmRepair with scanning. Two bodies are created: a horizontal flange with a hole and a separate body (highlighted in green color). Bodies can be unified using the Union command if required.

Settings

Prompts you:

Enable lofted bend repair? [Yes/No] <Yes>:

Switch on/off possibility to join adjacent lofted bends

From left to right:

Initial model with two lofted bend features
Model after SmRepair without lofted bend repair: the hole became perpendicular to the features faces.
Model after SmRepair with lofted bend repair: two lofted bend features are united to a single one.

SmConvert - automatically recognizes flanges and bends in a 3D solid.

SmDelete - removes a bend or a junction by restoring a hard edge between two flanges; removes a flange with all the bends adjacent to it. The adjacent flanges are extended up to a junction configuration with the flange being deleted.

SmDissolve - removes sheet metal data from the selected faces.
