This is the most important diagnostic tool. It checks for open profiles , isolated points, or overlapping lines that would cause a 3D feature to fail.

Frequently used for bolt heads and specialized fasteners.

Used for organic, aerodynamic, or complex curved shapes that don't follow a standard radius. 3. Constraint Toolbar: Driving the Design catia+v5+sketch+tools

A sketch is just a drawing until it is . Constraints turn lines into engineering data by defining size, position, and relationships.

Once the basic profile is drawn, the allows for quick refinements without redraws. Corner (Fillet): Rounds off sharp edges between two lines. Chamfer: Creates a flat angled cut at a corner. Relimitations (Trim/Break): This is the most important diagnostic tool

By mastering these tools, you transition from simply "drawing" in CATIA to "engineering" stable, parametric models that can withstand design changes and complex manufacturing requirements.

Avoid putting too much detail into a single sketch. It is better to have five simple sketches than one overly complex one. Used for organic, aerodynamic, or complex curved shapes

Ensures lines maintain a specific orientation to each other.
