[T MAKE 0] 3D Modelisation on Solidworks

[Work in progress]

Objective:

Before prototyping, you need to have a clear idea of your product (here your robot).
Making a 3D version of it will help you save time by avoiding conception mistakes.

This tutorial will explain to you how to create a 3D model with Solidworks.
We will take the example of a transmission gear to illustrate this tutorial.

A 3D model is:

• easily modifiable
• digital so it can bring it anywhere and share it easily
• free (no material or tools needed)

Requirements:

To complete this tutorial you will need:

• A computer with Solidworks installed (preferably with a good video processing capabilities)
• Measuring tools: A Caliper and/or a ruler
• Pen and paper to draw schematics
• Some time to waste

Steps:

Make a 3D part

1. Choose which piece you want to design, define clearly its features and its restrictions.
   ex: My gear needs to connect to my motor and to a transmission belt, I need to take in account the motor interface and the belt interface.
2. Measure the environment or the other parts that need to interact with the part you are making.
   ex: I need to have in mind:

• the actual empty space available for my part
• the emplacement of the screws on the motor
• the shape of the teeth and the radius of the gear for the belt

3. Draw the schematics of your part on paper from all the different necessary angles.

4. Start drawing on Solidworks

5. Add depth to your 2D schematic

6. Remove material

7. Add details

8. Bonus: Add texture

Make a 3D assembly

Conclusion:

Tips:

How to make a good 3D part:

1. Think about its usage
2. Think about the materials used
3. Think about the 3D printing restrictions
4. Think about structural robustness
5. Think about weight
