My CAD Project

Hello, for this CAD assignment, I designed a skateboard to demonstrate my understanding of several CAD skills including, sketching, extruding, assemby, mechanical drawings, and creating a BOM. Here is my CAD project using Onshape:

SKETCH

I started by sketching the skateboard deck using the sketch tool. I drew a long rectangle and another two rectangles on each side. I used the construction tool to find the centre of my two additional rectangles and drew a line through that to find a middle point. I then created a half circle on that line.

Furthermore, I also sketched out the trucks in a seperate part studio and the wheels aswell.

EXTRUDE

Once my sketches were all complete, I first used to extrude tool to make my deck have curved edges. I was able to do this by slecting the parts that were not within the half circile and removing them with the extreude tool. I then extruded both the wheels and the truck.

ASSEMBLY

Next, I went into the assembly studiom to combine all my parts. I attached the trucks and wheels to the bottom of the deck using align and mate tools. I used the revolute tool to make sure that all my wheels were centered and attached to the truck. Finally this made the skateboard look like a real object that could actually roll.

MECHANICAL DRAWINGS

After completing the model, I created a mechanical drawing that includes:

• Top view with full board dimensions
• Side and front views showing wheel placement and angles
• An Isometric view to show how the whole skateboard looks assembled

All relevant dimensions, such as the: deck lenght, deck thickness, wheel width, etc.. are clearly labeled. You can see these in my drawing below.

BILL OF MATERIALS (BOM)

I also included a bill of meaterial in my drawing. The BOM lists all the components used:

ITEM	QUANTITY	PART NUMBER	DESCRIPTION
1	1	Board 1	black paint on top
2	1	4 sets of wheels

This table helps identify what parts are needed to fabricate or 3D print the skateboard. For the wheels you will only need to print it once as it has 4 wheels in the part’s studio. You can also choose to paint the top of you skateboard black to better identity which side is the top or bottom.
