## What do you mean by ISO constraints?

ISO- Constraints-: When degrees of freedom of geometry have been taking up by a predictable combination of measurements and fixed geometry. That geometry is said to be ISO-CONSTRAINED.

## What is the use of constraint in Catia?

Constraints allow you to position mechanical components correctly in relation to the other components of the assembly. You just need to specify the type of constraints you wish to set up between two components, and the system will place the components exactly the way you want.

## What is under constrained fully constrained and over constrained sketch in Catia?

You can work with Under-constrained sketches but it is not good design practice and may create unexpected errors in design and in assembly. Over-constrained sketch is one in which duplicate dimensions or conflicting geometric constraints or both are present.

## What do you mean by constraining a sketch?

Constraints are automatically applied as you sketch. The constraint symbol on the cursor shows the constraint type. 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.

## What is the full form of CATIA?

CATIA (Computer-Aided Three dimensional Interactive Application) software is a complete multi-platform solution for computer-aided design, manufacturing, engineering, 3D and PLM.

## What is meant by over constrained?

Also in engineering and mathematics, overconstrained is used when there are too many simultaneous equations to result in an exact solution. For example, fitting a line to many points is overconstrained because technically a line cannot be drawn simultaneously through all of the points.

## How do you show constraints in Catia?

Select Analyze -> Constraints . The Constraint Analysis dialog box is displayed. The Constraints tab displays the status of the constraints of the selected component: Active Component displays the name of the active component.

## 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.

## How do you fully constrain a sketch in CATIA?

Geometrical Constraints

- Keep only Geometrical Constraint activated.
- Click Circle from the Profile toolbar.
- Select the corner center to define the one of the circle.
- Drag the cursor to define the circle dimensions.
- Click in the geometry when you are satisfied with the dimensions.

## What is the color of under constrained elements in CATIA Sketcher?

White: Under-Constrained Element.

## What are constraints in Creo?

When you apply constraints, Creo Simulate associates the constraints with model geometry. For structural analysis, a constraint is an external limit on the movement of a portion of your model. For thermal analysis, a constraint is an external limit on the temperature of a portion of your model.

## What are three 3 constraints which can be used when sketching in Creo?

How to use Constraints in Creo Parametric Sketch

- Vertical (symbol “V”)
- Horizontal (symbol “H”)
- Perpendicular (symbol can be seen in following figure)
- Tangent (symbol “T”)
- Mid-point (Symbol “M”)
- Parallel (symbol can be seen in following figure)
- Coincident (symbol can be seen in following figure)

## What is use of symmetric 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.
