Positioning Components ‘Point-to-Surface’

This section describes commands which position a Component on the constrained centerline at a specified distance from the surface of a fixed design item.

Any p-point on the current element may be used for the maneuver, although the default is the origin. In no case is the geometry of the current element considered. However, the geometry of the referenced item is considered in one of three ways:

• If the item is a Design element, then its complete geometry will be considered.

• If the item is a Piping p-point at the Arrive or Leave of another Component, then the Tube cross-section at that point will be considered.

• If the item has no geometry, i.e. a non-piping p-point, or is a position, then only that point will be considered.

All the examples in this section assume Forwards mode. Generally, if Backwards mode is being used, the effect of each command is logically reversed.
