What is the use of symmetry constraint?

The Symmetry constraint command enables you to constrain two sets of entities in a 2D profile so that they are symmetric to each other with respect to a symmetry axis. The Symmetry constraint requires that the entities be input as 3 groups — First Group, Second Group and the Axis Line.

What is a contact constraint?

The Contact Constraint creates a constraint between a segment and a point, a line, or a plane. After selecting the command and a manikin segment, the system prompts you to select a point, a line, or a plane.

What does coincidence mean in Catia?

Coincidence-type constraints are used to align elements. Depending on the selected elements, you may obtain concentricity, coaxiality or coplanarity. The tolerance i.e. the smallest distance that can be used to differentiate two elements is set at 10 -3 millimeters.

What is use of coincident constraint?

The Coincident constraint causes two points to be constrained together, or causes one point to lie on a curve. In a 3D sketch, a coincident constraint can also cause points and lines to be constrained to surfaces. The yellow coincident dot represents the presence of the constraint.
