 This week I worked on defining my final project idea and started to getting used to the documentation process.

+This week I took on making a table that is 30inches high and 48 inches in diameter. 
+
+1. I designed a table using parametric approach to ensure we can easily adjust to the wood pieces we get that 
+doesn't use fasteners or glue
+
+2. I learned how to use the manufacturing side of Fusion and make cut paths
+
+3. I Made hardwood glue up panels for the first time and use the Festool Domino to install dowels to strengthen the boards 
+
+4. I learned how to run the Shopbot CNC and cut the table [Table top done, legs are in process]
+
+5. [STILL IN PROCESS] I learned how to finish the table

+## Partial parametric design

+This was a struggle for me and I only had limited success.

+Table top - this was pretty straight forward and thickness, slots side/location, and table top diameter were all working well. 
+
+Legs - here I hit a road block. Thickness and slot insert size worked well but when I tried the get the hight / width to work 
+I could not get it working.

+I also replaced the arcs I used to curve the feet with filet but did not manage to make it work 
+
+I designed 2 other leg shapes and still could get it to change hight and keep the shape.

+I was running out of time and decided to focus on Parametrics design for the  slot and materials thickness that 
+are as most important for this design.

+At a high level we had to follow these steps:

+First we had to install the right bit.

+**Loading**

+
+I hit an issue as my table top was 48 inches in diameter which is the exact range of the machine. The air cut looked 
+great but when we ran the cut it was a bit off and so I had to recut a slightly smaller diameter of 47 inches.
