Step 1: Insert a 8"x8" box that is 0.75" tall. 

Step 2: Place the workplane onto the top of the peg board and add a cylinder hole to the corner of the peg board. 

Step 3: Dimension the cylinder 0.25"x0.25"x2". 

Step 4: Duplicate the cylinder hole and move to the left 0.5".

Step 5: Repeat step 4 8x, until you have a total of 10 peg holes. 

Step 6: Group the cylinders and center them on the beg board. 

Step 7: Duplicate the group cylinders, moving it 0.5" upward. 

Step 8: Repeat step 7 8x, until you have 10 rows of cylinder holes. 

Step 9: Add a box hole to the corner cylinder that is 0.05"x0.1"x1" to serve as a notch for peg insertion. 

Step 10: Repeat steps 4-8.

Step 11: Duplicate one of the cylinder holes and notches to serve as the model for the peg board pins, moving it to the side of the work plane. 

Step 12: Select the peg board box and all cylinders and group together, creating the holes of the peg board. 

Step 12: Add a 7.5"x7.5"x0.25" box hole to the side of the peg board to allow placement of a base cover. 

Step 13: Insert a box hole that is 7.5"x7.5"x0.25" and center it to the pegboard. 

Step 14: Group the box hole and peg board together, making the underside of the peg board hollow. 

Step 15: Unhide the copied peg hole and make it a solid. This will be the starting place for making your pegs. 

Step 16: Make the cylinder 2" tall. Dimension the box addition 0.045"x0.1"x0.25", creating a notch that will secure the pegs when turn. 

Step 17: Align you peg with one of the holes and duplicate. Move the duplicate into another peg hole, marking the boundaries for a wall. Insert a box that is 1.25" tall and 2" wide and align it with the pegs. 

Step 18: Group together.

Step 19: Repeat Steps 17 + 18 to create walls of varying lengths.
