 # 3. CAD Design 
 
+**Goals**
+
 This week we are focused on exploring different design tools including the following:
 
 I had used Fusion 360 and Coral draw in the past and so decide to explore some more tools. 
 
-In particular
+Get through basic tutorials and some simple designs using the following:
 
 2D Raster - GIMP 
 2D Vector - Cuttle 
 3D CAD - Free CAD
 
-Evaluate and select 2D and 3D software
-Demonstrate and describe processes used in modelling with 2D and 3D software
-Have you answered these questions?
-Modelled experimental objects/part of a possible project in 2D and 3D software
-Shown how you did it with words/images/screenshots
-Included your original design files
+To design the same part of my final project using Fusion and FreeCAD and compare the experiences.
+
+
+**Accomplishments**
+
+Cuttle: Got basic understanding and created a simple Hexagon design. Cuttle felt easy to use 
+and will be a go to for me. 
+
+GIMP: Went through basic tutorial and logo design. I am very comfortable with JPG manipulation. When 
+I got into graphic design the process here did not feel intuitive to me. I see the power this software 
+and I think I would have to invest a lot more time in learning the system to be able to use it well. 
 
+FreeCAD: I liked this software a lot. It was easy for me to use for a simple part design
 
+Comparison Fusion 360 vs. FreeCAD: 
+I found the high level steps to be very similar. The basic operation were simple to follow. The FreeCAD
+process is a little more "choppy" since you move between different workbenches compared with the more 
+integrated Fusion360 experience. I found this "Choppy" approach and Workbench very easy to follow! 
+It felt easer to me then Fusion timeline. 
+
+For basic part design I would be comfortable with both and as non professional I very much appriciated the 
+FreeCad cost!

 ## Here we go....head to head...... Fusion360 vs. FreeCad

 The total dimension for the VWM is 35 cm wide, 45 cm deep, and 35 cm high

+**Fusion360**
+
+First I set up some user parameters I will use in sizing the spinning plate and it base 
+
+![User Parameters](../images/ImagW2/GraphicApps/40platebase1.jpg)
+
+Now I made a round leg for the plate to sit on 
+
+![Leg sketch](../images/ImagW2/GraphicApps/40platebase2.jpg)
+
+To create the shape of the base I will create a new sketch on the top of the base leg. I then
+create a circle and replicate it using the circular pattern tool followed but a cut.
+
+![Pattern](../images/ImagW2/GraphicApps/40platebase3.jpg)
+
+![Cut](../images/ImagW2/GraphicApps/40platebase4.jpg)
+
+I then sketched on top again and created a circle to create the plate itself 
+
+![Plate](../images/ImagW2/GraphicApps/40platebase5.jpg)
+
+Here I made a mistake as I did not select the whole plate and where the handy timeline 
+tool come into play
+
+![Plate](../images/ImagW2/GraphicApps/40platebase6correction.jpg)
+
+And we are back on track. I wanted to create a downward facing lip in order to provide some water 
+protection for the spinning mechanism during the dry cycle.
+
+To do this I am going to draw a sketch of the lip and have it rotate around the plate center axis
+
+Start with sketch
+
+![Plate lip](../images/ImagW2/GraphicApps/40platebase7lip.jpg)
+
+Then used the revolve to create the lip and set it to join the plate base.
+
+![Plate lip](../images/ImagW2/GraphicApps/40platebase8revolve.jpg)
+
+and there you go a first cut at the base plate 
+
+![Plate](../images/ImagW2/GraphicApps/40platebase9.jpg)
+
+
+Now let do that again in FreeCad
+
+
+
+**Free CAD**
+
+I will follow the same overall process, starting with defining the user parameters 
+
+![User Para](../images/ImagW2/GraphicApps/50Platebase1userpara.jpg)
+
+You need to remember to name the cell with the number itself in the top right 
+
+![User Para](../images/ImagW2/GraphicApps/50Platebase1userpara2.jpg)
+
+Then you right click on the number and set the unites to mm 
+
+Finally when setting the variable you need to type the spreadsheet and then variable name
+
+
+![User Para](../images/ImagW2/GraphicApps/50Platebase1userpara3.jpg)
+
+I then added a circle sketch and used Pad to create the leg
+
+![Leg](../images/ImagW2/GraphicApps/50Platebase2sketch.jpg)
+
+
+![Leg pattern](../images/ImagW2/GraphicApps/50Platebase2pad.jpg)
+
+
+Then I added a pocket all the way through and used the polar pattern feature to 
+repeat around the leg.
+
+
+![Leg pattern](../images/ImagW2/GraphicApps/50Platebase2cut.jpg)
+
+
+I found the tutorial very helpful in creating patterns 
+
+[Pattern video](https://youtu.be/Z2eXF4ITBeM)
+
+Now it is time to create the plate itself. Since we are building a sketch on top 
+of another shape we need to use the extrude command vs. pad.
+
+![plate](../images/ImagW2/GraphicApps/50Platebase3.jpg)
+
+Now we need to create the lip to finish this part. 
+
+I started off by creating a sketch on the XZ axis to create the profile of the lop
+
+![lip](../images/ImagW2/GraphicApps/50Platebase4.jpg)
+
+And using the revolve command we got the lip to go around finishing the plate design 
+
+

+
+
+**Conclusion** I found the basic part creation that both FreeCad and Fusion did a good job. 
+Knowing fusion a little bit helped me understand the concepts and it was just matching the right
+commands. 
+
+I did not try any of the more advanced features but for basic features I think FreeCAD is a good 
+solution for the price!!
