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:

	= 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:

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 +/- 5 degrees
