Interface DesignConnector (Models.OCCT)

A named frame on a part, where an assembly fastens it to another: on the one flat face on names, facing out of it, with its x axis along direction laid into the face. Its origin is where origin, or the document's origin when it is left out, meets the face's plane square on, so it stays on the face when a parameter moves the face; or where the axis of the cylindrical face axis names crosses the face, such as a hole's wall; or the centre of the circular edge centre names, met square on. An axis that names the walls of a hole with no from makes a set: one connector per position of the hole, named <id>.<position id>, which a component's replicate places on. direction may be left out on a face facing along a world axis (it is then X, or Y on a face facing along X), and is needed on any other. It follows the face through rebuilds as references do.
