The Extended sheet metal options area of the Auto Feature dialog box 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 is hidden until the following conditions are met:
You must select the Show Extended Sheet Metal Options check box on the General tab in the Setup Options dialog box (select Edit | Preferences | Setup or press the F5 key to access this dialog box.
The type of Auto feature must support the extended options.
Except for Corner Point and High Point, all other Contact and laser Auto features support the Extended Sheet Metal Options area.
You must select the >> button in the Auto Feature dialog box for Show Advanced Sheet Metal Options.
You must select the >> button in the Auto Feature dialog box for Show Extended Sheet Metal Options. This button appears only for supported features.
This displays the Auto Feature dialog box with all of the available options visible.
Extended Sheet Metal Options
Depending on the feature you selected, the following items appear in the Extended sheet metal options area.
IJK Edge Report boxes
These boxes display the vector used for reporting deviation. This is a user-supplied I, J, K vector.
For the Line and Edge Point features, these boxes display the vector for the RT computation.
The Location Dimension option RT displays the deviation calculated along this vector. After the new value is created, PC-DMIS will normalize the vector, making its length one unit.
Supported Auto features: Line, Edge Point
IJK Update boxes
These boxes display the updated vector that PC-DMIS uses 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.
Supported Auto features: Vector Point
IJK Surf Rpt boxes
These boxes display the vector used for reporting deviation. This is a user-supplied I, J, K vector.
For the Line and Edge Point features, these boxes display the vector for the RS computation.
For the Angle Point feature, these boxes display the vector for the RT computation. You can use these boxes to deviate from the S and T deviations on the dimension for an Angle Point feature.
For features that display only the IJK Surf Rpt boxes (they do not display the IJK Edge Report boxes), these boxes display the vector for the RT computation.
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.
Supported Auto features: All features, except Corner Point, High Point, and Sphere
IJK Surf1 Rpt and Surf2 Rpt boxes
These boxes display the surface vectors for the RS (deviation along surface report) computation. You can use these boxes to deviate from the S and T deviations on the dimension for an Angle Point feature.
Supported Auto features: Angle Point
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.
Supported Auto features: 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.
Supported Auto features: Circle, Square Slot, Round Slot
