### Extended Sheet Metal Options area

This area contains some of the less frequently used sheet metal options for supported auto features.

Showing Extended Sheet Metal Options

The Extended sheet metal options area remains hidden until the following conditions are met:

- You must select the Show Extended Sheet Metal Options check box from the General tab of the SetUp Options dialog box (select Edit | Preferences | Setup).

- The type of auto feature must support the extended options. Supported features include: Vector Point, Surface Point, Edge Point, Circle, Round Slot, and Square Slot

- You must select the >> button on the Auto Feature dialog box for Show Advanced Sheet Metal Options.

- You must select the >> button on the Auto Feature dialog box for Show Extended Sheet Metal Options. This button only appears for supported features.

This will display a rather tall Auto Feature dialog box with all available options visible.

The Extended Sheet Metal Options

Depending on the feature selected, the following items appear in the Extended sheet metal options area.

Item | Description | Supported Auto Features
| IJK Edge Report boxes | These boxes display the vector used for reporting deviation. This is a user supplied I, J, K vector. The Location Dimension option RT will display the deviation calculated along this vector. After the new value is created, PC-DMIS will normalize the vector, making its length one unit. | Edge Point
| IJK Update boxes | These boxes display the update vector to be used to pierce the CAD surface, if the option is active by setting the SET NOM AX mode. This is a user supplied I, J, K normal vector. The I, J, K should always point away from the surface. After the new value is created, PC-DMIS will normalize the vector, making its length one unit. | Vector Point
| IJK Surf Rpt boxes | These boxes display the vector used for reporting deviation. This is a user supplied I, J, K vector. After the new value is created and you exit the dialog box, PC-DMIS will normalize the vector, making its length one unit. The Location dimension's RS check box displays the deviation calculated along this vector.

The Location dimension's RT check box displays the measured deviation in the surface vector direction along this defined report vector.

All

| Use Pin list | By setting the Use Pin list to Yes, the IJK Punch and IJK Pin boxes become available for editing. The default value for this for new Auto Features is No. | Circle, Square Slot, Round Slot
| IJK Pin boxes | These boxes define the vector of the stud through the hole formed by the punch. When pins are created on a sheet metal surface they are not always perpendicular to the surface. This naturally creates an elliptical shape at the surface of the metal, even though a round pin may have been used. The Pin vector then allows for more accurate measurement and data analysis in this situation. | Circle, Square Slot, Round Slot
| IJK Punch boxes | These boxes define the vector of the punch through the sheet metal. This vector is positioned at the XYZ center, plus half the thickness along the surface normal vector. The punches used to place holes in sheet metal are not always perpendicular to the surface. This naturally creates an elliptical shape at the surface of the metal, even though a round punch may have been used. The Punch vector then allows for more accurate measurement and data analysis in this situation.

For the Circle feature, the diameter of the feature is also along this vector.

Circle, Square Slot, Round Slot
