23.13. - For the second mate, select the two cylindrical faces indicated, a bolt hole

from the 'Side Cover' and a screw hole from the 'Housing'. SOLIDWORKS defaults

again to a Concentric mate and rotates the 'Side Cover' to align the holes; this

mate will prevent the 'Side Cover' from rotating. Remember we can use the

"Magnifying Glass" (Shortcut "G") as we did to make selection of small faces

easier. Click OK to add the mate. IF the 'Side Cover' is inside the 'Housing', click-

and-drag it with the left mouse button to move it out and add the remaining mates.

The "Lock Rotation" option in the concentric mate prevents the mated parts

from rotating. Checking this option in the first concentric mate would

eliminate the need to add the second concentric mate.

In this case adding a second concentric mate works as expected because

both holes are located exactly at the same distance from the center in both

parts; in reality, if the holes were not exactly aligned, SOLIDWORKS would

give us an error message letting us know that the mate cannot be added. In that

case, it is better to align the two components using component Planes and/or

Faces, with either a Parallel or Coincident mate, as will be shown later.

23.14. -The last mate will be a Coincident mate between the back face of the

'Side Cover' and the front face of the 'Housing' to make the faces touch; use the

"Select Other" tool, or rotate the view to select the faces needed. (If the 'Side

Cover' is inside the 'Housing', click-and-drag to move it out.) After selecting the

two flat faces, the cover will move until the selected faces touch; the Coincident

mate option will be pre-selected as the concentric mate was preselected when

selecting cylindrical faces. Click OK to add the last mate and close the "Mate"

command by either clicking OK, Cancel or pressing the "Esc" key.
