3D Finish design

Purpose-

Perform 3D finish on the Assembly design & Write a Detailed Report describing the process (what changes are made on the design) and attach relevant images.

Answer -

- 3D finish is the process where design is being completely finish & to be ready for final simulation & 2D detailing

- Following points are taken into consideration while finishing the design.

1. Hole concentricity & hole sizes- All parts Hole concentricity is checked & confirmed while finishing the parts.
2. Machining Area- The machining area in every part is defined & the machining area is highlighted by using orange color.
3. Nominality- All units dimensions are maintained nominal to facilitate easy assembly of the unit.
4. Holes colouring standard- Color Code standard used in the 3D finishing
   1. Cyan - Simple Hole
   2. Yellow - Threaded Hole
   3. Orange - Machined area
   4. Blue - Dowel pin Hole
5. Fasteners implementation- Fasteners are implimented in all unit as per the requirement & load on the part.
6. Avoiding clash between different part- Proper gap is maintained between parts to avoid the clash.
7. Mylar splitting as per panel profile- Mylar splitting are confirmed while finishing the design.
8. Proper renaming of parts/assemblies as per standard-proper renaming of parts & assemblies are done while finishing the design hence we can identify each & every part easily with unique identification.

- All the units designed are finished in 3D finish by considering the above points.

- All 3D finish parts & the parts designed at start are shown below. which shows the diffrence before finishing & after finishing of the parts.
