How do you constrain a sketch in Catia?

What does it mean to constrain a sketch?

Constraints prevent unwanted changes to a feature when dimensions are changed or referenced geometry is moved. You can add or edit constraints and dimensions to control sketch shape and size. Before you add constraints , study your sketch to decide which are needed.

What are automatic sketch constraints?

Geometric constraints are created automatically between lines, arcs, and other geometry as you sketch. Constraints can also be manually applied after the sketch geometry exists to stabilize sketch shape or position.

Why are my lines Blue in Fusion 360?

Blue lines mean that the sketch object is not fully constrained and dimensioned also sometimes referred to as not fully defined. A sketch item will turn from blue to black as soon as it is fully defined.

What is the purpose of a sketch constraints?

Geometric constraints are created automatically between lines, arcs, and other geometry as you sketch. Constraints can also be manually applied after the sketch geometry exists to stabilize sketch shape or position. These geometric constraints allow the sketch to be edited with predictable results.

Why is it important to fully constrain a sketch?

The importance of fully constraining your sketches in Inventor cannot be over stated. When a part or sketch is not functioning correctly, it can almost always be traced back to an unconstrained sketch.

How do you constrain a sketch in SpaceClaim?

How do I constrain my sketch? Sketches are not constrained in SpaceClaim because they are not intended to persist. Create a sketch to the correct dimensions, turn it into a surface, and then use the Pull tool to pull it into a solid. For best results, make edits to the resulting solid rather than editing the sketch.

How do you constrain to Origin?

Right-click the Origin folder in the browser, and select Expand All Children to see the browser nodes you use to select the origin geometry when it is not displayed. On the ribbon, click Sketch tab Draw panel Project Geometry. Select the browser node Center Point to include the origin point as a point in your sketch.
