What does the "Project Geometry" feature do in a sketch?

The "Project Geometry" feature in a sketch is primarily used to incorporate existing edges, points, or curves from other parts or assemblies into your current sketch environment. This tool is particularly useful in maintaining design intent and ensuring that the new sketch elements are accurately aligned with existing geometry. By projecting geometry, you can create constraints, reference points, or outline shapes based on features that are already present in your model, allowing for more efficient and accurate design processes.

Using project geometry enhances your workflow by allowing you to make connections between various components and ensuring that any updates to the original geometry are automatically reflected in your sketch. This is crucial for complex designs where precision and alignment with existing parts are necessary.

In contrast, creating new shapes from scratch focuses on starting a sketch without any external influence, measuring dimensions relates to the measurement tools available in the sketch environment, and modifying properties concerns editing existing shapes rather than referencing them.
