Modeling the Tails

Create a new part with the same dimensions (3.5" wide, 12" long and 0.75" thick) and save it with the name "tails". Create a new sketch the same way as before, but this time select one of the sides of the board, like this:

Activate the 2D sketch on this face and create the reference figures like you did for the pins. Again, be sure the sketch is not activated, then switch back to Dovetail Jig for Alibre Design. To get the application to recognize the new part, just double-click somewhere in the "Part" box. Select the "tails" part and then select "Sketch<2>", which should appear in the "Valid Sketches" area.

In the Step 2 area, select Tails so the application knows you want to model tails instead of pins. (The "Blind" amount should still be set to 0.125 inches if you haven't closed the application. If you did, just change this value to 0.125 again, either by typing in the new value or by clicking the up arrow.) In the Preview area you'll notice that the tails are configured along the length of the board, which is probably not what you want! Put a check mark in the "Turn" check box at the bottom of Step 3 and the tails will move to the end of the board. It should look something like this:

By default tails are cut and not extruded. (Extruding tails out from the face of the board would be a bit odd, but if you want to you can.)

Now click "Make Feature" to carve out the tails. Switch back to the Part in your Alibre Design session and you should see perfect tails.

Now let's join the parts.
