Creating a Cutout

Open the NEWCutout1.CATPart document.

Standard cutout

1. Click Cutout .

   The Cutout Definition dialog box is displayed.

   The surface to be impacted by the cutout is displayed in light blue.

2. Select a profile (sketch.3 in our example).

   A preview of the projected cutout is displayed.
   	You are strongly advised to use a closed profile to create a cutout. In case you create a cutout from a profile containing more than one open contour, you are warned that the cutout may fail.
   Once the profile is selected, you can modify it by clicking Sketcher .
   	The Reverse Side option lets you choose between removing the material defined within the profile, which is the application's default behavior, or the material surrounding the profile.  The Reverse Direction option allows you to invert the direction of the extrusion pointed by the arrow.

3. Click OK in the Cutout Definition dialog box.

   The cutout is created.
   	Several end limit types are available: Up to next: the limit is the first face the application detects while extruding the profile. This face must stops the whole extrusion, not only a portion of it, and the hole goes through material. Up to last: the last face encountered by the extrusion is going to limit the cutout. Dimension: the cutout depth is defined by the specified value.

4. In the specification tree, double click on Cut Out.1 to display the Cutout Definition dialog box.

5. Click More>> to display the maximum information.

   Here the Cutout's impacted skin is set to Default, that is, the surface on which lies Sketch.3

6. Click on and select the support for the cutout.

   The Support Selection dialog box is displayed.

7. Select Wall.1 as your new support for the cutout.

   	Should you want to perform a cutout on the opening line (unfold reference) of a rolled wall or a hopper, you must select the rolled wall or the hopper feature as the support for the cutout.

8. Close the Support Selection dialog box and click OK in the Cutout Definition dialog box.

   The cutout is created on Wall.1.
   	Specifying the support for the cutout avoid confusions in case of overlaps.
   For instance, if you try to create a cutout on the part below, the following message is displayed:
   To avoid this, you have to select the exact support for the cutout.
   	When Lying on skin is checked, The End limit and Start limit types are automatically disabled, The Depth field is disabled, The skin to be impacted is displayed on the part. The cutout is not projected anymore on the skin. It is based on a sketch that inevitably lies on a surface. This option is available only when creating a standard cutout.
   	In case the prism resulting from the cutout's profile and direction is tangent to the impacted skin, the projection is non-valid and the cutout cannot be created. To avoid this, check Lying on skin or select a wall as support to be able to create your cutout.

Pocket cutout

Open the NEWCutout1.CATPart document again.

1. Click Cutout . The Cutout Definition dialog box is displayed.

2. Select Sheetmetal pocket as Cutout type in the combo box.
   The skin to be impacted remains grey and the End limit type is disabled.

3. Set the Depth to 1mm.

4. Select Sketch.3 as profile.

   A preview of the cutout is displayed. In our example, the cutout will impact only half the wall.

5. Click OK in the Cutout Definition dialog box.

   The cutout is created.

6. In the specification tree, double click on Cut Out.1 to display the Cutout Definition dialog box.

7. Click More>> to display the maximum information.

   The Direction is already selected (Sketch.3). By default, it is set as normal to the profile.

8. Uncheck Normal to profile.

9. Click inside the Reference field to activate it.

10. Select Line.1 to perform a cutout normal to the line direction.

    	Should you need to create a line, right-click on the Reference field and select Create Line.
    	Refer to Creating Lines for further information.

11. Click OK to create the cutout normal to the line direction.

    	The pocket cutout can be created only on a planar and single support surface (i.e. a wall or the planar face of a flange). Therefore, if the profile of the cutout is to impact several supports, use the sheetmetal standard type instead. May you want to create a cutout on an overlapping element or a bend with radius=0, either choose the top skin of the element (as shown in the picture above), or unfold the part to create the cutout. You cannot create a pocket cutout on a surface flange. You cannot create a standard cutout on a pocket cutout a standard cutout or any other feature built by thickening on a pocket cutout. You can create a pocket cutout on a standard cutout; a pocket cutout on a stamp; a pocket cutout on a pocket cutout.
