CAD PROJECT – MUG

LINK TO PROJECT

Since I have only worked with TinkerCAD for my CAD experience and have never worked with OnShape, I decided to use a tutorial and choose a simpler shape for my first project. I created a mug to learn the basics of OnShape. I followed a YouTube tutorial for this project. The steps are as follows:

I started with the mug body, creating a circle and extruding it upwards. Then, I used the shell tool to make the inside of the mug. For the lip of the mug, I used the fillet tool to give it a smoother edge, rather than a sharp edge.

Next, I had to make the mug handle. I created a sketch using the spline tool to create a shape for the handle.

I then created 2 ellipses for the handle’s anchor points and used the sweep tool to create thickness for it.

While I completed the mug, there was an issue: I could not mate the handle of the mug to the mug, which is a curved surface. The assignment required me to have a mate in the project, and after spending quite a bit of time on it, it seemed impossible, therefore I resorted to creating a coaster which was mated to the mug base.

Mechanical Drawing

CAD Skills used:

• Extruding
• Shelling
• Sweeping
• Assigning Materials to Object
• Creating BOM
• Mechanical Drawing
• Fastened Mate

Some challenges I faced as this was my first time using OnShape were the mechanical drawings. I had some difficulty getting some measurements and showing the dimensions on the drawing, for example: the curve of the Handle side view. This proved to be a challenge because of the nature of the curve, having no points on the sketch where the software could put a “point” to start the measurement. After strenuous searching, I could not find a solution for this issue, as Mr Crompton told me to leave it.
