# You asked: What is the color of under constrained elements in Catia Sketcher?

White: Under-Constrained Element.

## What is the Colour of fully constrained sketches?

Sketch geometry changes color to black when it is fully constrained.

## What is under constrained?

If you do something under constraint, you do it only because you have been forced to: They confessed, but only under severe constraint.

## What are the constraints in Catia?

Geometrical constraints include Parallelism, Symmetry, Coincidence, Tangency, Midpoint, Perpendicular, Concentricity, etc. Geometrical constraints are usually given automatically by the software, but at some place we may need to give a particular constraint.

## Why do you need to fully dimension and constrain geometry?

Apply geometric constraints before dimensions so that the sketch shape is less likely to distort. Use both geometric constraints and dimensions. Some constraint combinations can distort under-constrained portions of the sketch.

## Why are my dimensions pink in Catia?

Pink means dimensions not upto date.

## What is ISO constraints in Catia?

What do you mean by ISO-Constraints? If all of the degrees of freedom of geometry have been takes up by a consistent combination of dimensions & fixed geometry. That geometry is said to be ISO-CONSTRAINED. Geometry that still has some degrees of freedom is said to be UNDER constrained.

## What is over constrained means in NX?

Geometry will be marked as over-constrained when it cannot be solved because there are too many dimensions acting on it for the degrees of freedom available.

## What do you mean by constraining a sketch?

A constraint is a condition defining the geometry of the entity or a relationship among entities. Constraints can refer to geometry entities or construction entities. Create constraints or accept the constraints offered as you sketch. You can select an existing constraint, delete it, or get more information about it.

## What is the meaning of geometrical constraint?

A geometric constraint is a non-numerical relationship between the parts of a geometric figure. Geometric constraints: Associate geometric entities together two by two (coincident, concentric, collinear, parallel, perpendicular, tangent, smooth, symmetric, equal).

## What are some assembly constraints?

This article describes the constraint types available in Assembly Design.
