## Extended Sheet Metal Vector Diagrams

This topic contains various diagrams illustrating the vectors that you can use when you choose the show extended sheet metal feature options:

Normal Vector: The normal vector is the vector perpendicular to the surface at a point feature’s location. See the diagram below:

| = Normal Vector
| = Surface
| = Point Location

Update Vector: The update vector is the vector used to determine the direction to follow when updating a point to a new surface. This update vector is derived from the reference line used in the initial creation of the feature. See the diagram below:

| = Updated or new surface
| = Original or old surface
| = Original point location
| = Updated point location
| = Reference line used to generate point location. Also known the update vector.

Report Vector: The report vector lets you control the direction of the deviation by allowing you to define a vector onto which the deviation along the surface vector is then projected. The report vector may differ from the surface normal, such as along a specified axis (shown below as either Yr or Xr). See the diagrams below:

| = Theoretical surface
| = Nominal point location
| = Actual point location
| = Deviation in X axis
| = Deviation in Y axis

| =Report vector
| =Surface vector deviation projected to the report vector
| =Probe tip contacting actual surface

Pin Vector: Applied to slots and holes, the pin vector specifies the vector of the pin as it locates the product. See the diagram below:

A | = Pin vector

Punch Vector: Applied to slots and holes, the punch vector specifies the direction of the punch used to create the feature. This vector is usually close to the surface normal within a few degrees. See the diagram below:

A | = Punch vector. Close to the surface normal within + or - 5 degrees
B | = The Punch
