Assembly Snaps

The assembly snap applies specific behaviors to the components to be moved in Snap and Smart Move and Smart Move with Viewer commands.

Two kinds of snap can be used in an assembly, Simple Snap and Double Snap:

The Simple Snap applies the minimal transformation when moving a geometrical element of a component onto another geometrical element belonging to the same or to a different component. The Simple Snap reorients the first geometrical element according to the second geometrical element and projects the selection point of the first geometrical element onto the second geometrical element.
The Double Snap moves and reorients a geometrical element of a component onto another geometrical element belonging to the same or to a different component. The Double Snap reorients the first geometrical element according to the second geometrical element and makes coincident the selection points of these two geometrical elements.

Depending on the selected elements, you will obtain different results, this table indicates what you can do and obtain:


First Element Selected	Second Element Selected	Simple Snap Result	Double Snap Result
axis system	axis system	Identical axis systems, origin and axes.	Identical axis systems, origin and axes.
axis system	point	The axis system origin is coincident with the point.	The axis system origin is coincident with the point.
axis system	line	The axis system origin is projected onto the line.	The axis system origin is coincident with the selection point onto the line.
axis system	plane	The axis system origin is projected onto the plane.	The axis system origin is coincident with the selection point onto the plane.
point	axis system	The point is coincident with the axis system origin.	The point is coincident with the axis system origin.
