Corner reliefs

CornerSee FilletRounded corner at the intersection of two lines or edges; concave intersection between two surfaces. Fillet refers to an interior corner; exterior corner is known as a round. You can draw a fillet using the Create Rounded Corner tool or by selecting the Fillet (Constant radius round) option from the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. options. See RoundRounded corner at the intersection of two lines or edges. Round refers to an exterior corner; an interior corner is known as a fillet. Rounds and fillets are both called rounds. See Fillet, Constant-radius round, Variable-radius round.. (interior corner) or Round (exterior corner) reliefs are created automatically when you create a sheet metal design or convert a design to sheet metal.

The corner relief type is determined by the Corner Relief option tool in the Modify group on the Sheet Metal tab. The default type is square, but you can change it to another type. The icon on the Corner Relief option tool changes to reflect the corner relief type. This setting is saved until you close SpaceClaim.

You can select a corner relief and view its properties in the Sheet Metal section of the Properties panelArea of the user interface that displays editable details about the selected object(s). This panel is initially displayed on the lower left side of the screen, but can be moved..

You may need to create a corner relief on a sheet metal part, for example, when you import a shelled part that doesn't have any reliefs, or when you want to convert a watertight corner to a regular corner. When you change a sharp edge to another junction type or when you split a wall at a corner, corner reliefs are automatically added.

To add a corner relief

1. Select an option from the Corner Relief tool in the Modify group on the Sheet Metal tab.

2. Select one or more points where you want a corner relief added.

To change the type of a corner relief

1. Select one or more corner reliefs by clicking any face in the corner relief.
2. Select an option from the Corner Relief tool in the Create group on the Sheet Metal tab:

    

   Corner relief type	Icon	Application
   Default		Any corner
   Filled		Any corner
   Smooth		Corners between bends or angles
   Square		Any corner
   Circular		Any corner
   Triangular		Any corner
   Rectangular		Any corner
   Oblong		Any corner
   Diagonal		Corners between bends of unequal radius or angles
   Laser Edge3D object composed of a single outside boundary of a feature. A line sketched in 2D becomes an edge when you pull your sketch into 3D.		Any corner
   Laser Symmetric		Any corner
   None		Any corner

    

3. You can also select a corner relief type from the mini-toolbar or modify the following values in the Sheet Metal section of the Properties panel:

   • Relief Type: Select a corner relief type.

   • Reference: Select Corner or Middle based on how you want the corner to be positioned.

   • Diameter, OffsetDistance an edge, segment, or curve is moved or copied., Width, Height: Enter values for the selected relief type.

      

     You may wish to rotate a wall. To achieve a solid rotation and retain correct geometry, before rotating a sheet metal wall face, you can automatically convert the corner reliefs to a default corner relief (which is purposely a bit over-sized). When finished with the rotation, the corner reliefs will automatically restore to their original relief type.

Some examples of Corner Relief types

Changing a corner relief type to Laser symmetric.
Selecting the Smooth option from the Corner Relief tool for unequal radius bends.
Selecting the Smooth option for a non-90-degree corner.

 

The following examples show the effect of the Reference corner relief property in an unfolded sheet metal part.

 

Corner relief type: Circular Reference: Corner
Corner relief type: Circular Reference: Middle
Corner relief type: Square Reference: Corner
Corner relief type: Circular Reference: Middle

 

Corner Relief added to a shelled part converted to Sheet Metal

 

 

Adding a corner relief to a shelled part that was previously converted to sheet metal. This part will need junctions and split faces before it can be unfolded.

 

To change a corner relief type back to default

1. Select one or more corner reliefs.

   You can select a Filled corner by selecting the vertex where the corner relief would be.

2. Select the Default option from the Corner Relief tool.

   You can also modify the Relief Type value in the Sheet Metal section of the Properties panel.

 

To create a smooth corner relief between equal bends

1. Ctrl + click to select equal bends neighboring a corner relief.

2. Select the Smooth option from the Corner Relief tool.

To remove a corner relief

To remove but leave the geometry

1. Select one or more corner reliefs.

2. Select  None from the Corner Relief tool in the Modify group on the Sheet Metal tab or from the mini-toolbar.

   The corner relief object is removed. The geometry remains.

To remove by filling

1. Select one or more corner reliefs.

2. Click the FillUse the Fill tool to simplify or clean up geometry by extending surrounding faces to eliminate a selection. The selected region is filled in or healed with the surrounding surface or solid. tool in the Edit section of the Design2D or 3D model that contains at least one top-level component. tab.

When a corner relief is filled, it will be filled with a radius to match the inside radius of the bend and create a corner object.
