Surface Mesh Snap on Match Flag

Surface mesh snap on match flag turns on/off the "snapping" of destination vertices during the mesh matching. By default it is set to On.

Normally when the mesher performs the transformation during mesh matching it will "snap" the destination vertices to the destination entity by doing a closest point calculation. This ensures that the modeler will consider the points to be on the destination model entity, but means that points may not be at the exact location given by the transformation. However if this option is set to Off, the default behavior will be disabled and the snapping will not be performed. This can result in a mesh that is inconsistent with the model if the transformation given does not result in the points being within tolerance of the model entities.
