When you give numerical value to a geometry, it means you have given Dimensional constraint. It may be Length or Angle. As shown in the figure below, the start point of the line is at (0, 0) and the end point is automatically described by length and angle. This makes the line fully constrained.

## What is the difference between geometric and dimensional constraints?

There are two types of constraints: geometric and dimensional. Geometric constraints are used to control the relationships of objects in respect to each other. Dimensional constraints are used to **control the distance, angle, radius**, and length values of objects.

## 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 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 constraints in drawing?

Constraints are **rules that are applied to 2D geometry**. By applying constraints, you can control the location, size, distance, angle, and other parameters of objects in a drawing.

## What are Catia constraints?

To create a precise 2D sketch in CATIA, we use constraints. … It means that **we are restricting the degree of freedom of the sketch**. Consider, you want to constraint a line. If you provide its length, then it ensures that the length of the line is under control.

## What is a numeric constraint?

Numeric constraints are **simply number values**. They can be integers or algebraic equations used to control the dimensions or location of a geometric figure. … The length, width and depth of a geometric figure are examples of numeric constraints.

## Can a drawing be a model?

Both the drawing and modeling approaches to design result in a familiar engineering drawing. In the 2D approach, the drawing captures the physical information needed to create the part. In the solid modeling approach, the drawing is one of several uses for the created model.

## What is a functional constraint?

The functional or selective constraint **defines the range of alternative nucleotides that is acceptable at a site without affecting** negatively the function or structure of the gene or the gene product. … The higher the functional density, the lower the rate of substitution is expected to be.

## What are dimensional and geometric constraints?

Geometric Constraints. Geometric Constraints – relationships between sketch entities. … Dimensional constraints **show a linear or angular distance between entities**. Geometric constraints are more fundamental than this and describe the characteristics of the relative position of entities.
