Week 2 - Journal

Designing was kind of fun since it can be done through many ways in fusion 360.

1. The arm middle line was drawn and dimension according to standard.

2. A fillet was added with a radius of 22.5mm.

3. Here comes a tricky but essential step, Planes, the first plane is the front plane (standard one), then an angled plane with 45 degrees inclination was made and offset to 2 position along the arm middle line and a 1 normal front plane offset was made.

4. On the front plane, the start geometry of the arm was drawn according the dimensions set before in the glasses front frame.

5. In the second plane (near the end of the straight line before the fillet), the end geometry of the arm was also drawn as shown.

6. In the third plane (inclined plane after the fillet), geometry was altered to be smooth as possible, so, a circle was drawn.

7. In the last one, a smaller circle was drawn keeping in mind that the center of all those geometries are made Coincident with arm middle line.

8. Using the loft feature, the four geometries were connected, and the first profile was edited in the setting of the loft to be directional and set manually to have a proper shape.

9. A proper fillet was added to the end of the arm.

10. Using the front plane again, both connection extended parts of the arm weredrawn and dimensioned as shown.

11. Using sweep feature, the sketch as profile and the edge as the path, the connection was extruded (the proper value was 0.016 and produced almost 2mm thickness).

12. Saved the file as STL, then modified sweep sketch to get the second arm and exported the second arm STL file.

Final output 

Applying the concept of mixed design in the final project would really help, allowing different techniques to be used together to assemble the final project, also, the efficient usage of all the materials available to us instead of depending mainly on one resource or material.
