PARTS
Creating a part model is a fundamental process in designing in 3D. It begins with sketching, where users define the 2D profiles or shapes that will form the basis of their part. These sketches are created on a specified plane, providing a starting reference for building the part's geometry.
Once the sketch is complete, users can apply constraints to control the relationships and dimensions of sketch entities. Constraints ensure that the sketch remains flexible and adaptable, allowing easy modifications and maintaining design intent throughout the modeling process.
After sketching, users can employ various 3D modeling tools to extrude, revolve, sweep, loft, or use Boolean operations to give depth and volume to the part. These operations enable the transformation of 2D sketches into 3D objects with complex shapes and features.
The video tutorials for the example drawings found below were produced using Onshape. During the modeling process, Onshape's parametric capabilities play a crucial role. Users can establish parameters for dimensions, features, and other properties, making the part's design easily adjustable and customizable. Any change to a parameter updates the entire part, ensuring consistency and efficient design iteration.
Additionally, Onshape's feature history allows users to review and modify each step of the modeling process. This non-destructive approach to design enables easy modifications without starting from scratch. The software's parametric and feature-based approach ensures flexibility, efficiency, and the ability to maintain design intent, making Onshape a powerful tool for designing complex and customizable 3D parts.

How to Make a Drawing Sheet
Once you have parts drawn you will want to place them on a drawing sheet so that you can dimension the drawing. This allows you to give someone your drawing sheet and they will have enough information to actually produce what you have drawn.
