** CATIA Interview Questions**

- What is the difference between Split and trim?

The differences between Split and Trim are as follows:

- Use Split with lines, curves, or surfaces to cut with a plane or surface. It is also possible to cut solids using the Part Design workbench.

- Trim can be used in conjunction with lines, curves, or surfaces to cut and join the remaining sections. Trimming can also be used within a sketch.

- What is the definition of NURBS?

NURBS (non-uniform rational B-splines) are mathematical representations of two- or three-dimensional objects that can be standard shapes (such as a cone) or freeform shapes (like cars). NURBS are utilised in PC graphics and the CAD/CAM industry and have become a standard technique for creating and representing complex objects.

- Where do we employ the axis? What is the distinction between the axis and building components?

Axis is utilised in the production of the Shaft, the rotating component. Axis is discernible in extent-designing mode and can be selected. However, construction elements are not visible and cannot be set for some parts in the design.

A construction component is a 2D geometric element that is not used to create geometry but to position other 2D geometric elements. In a sketch, dashed lines indicate a development element. A rotating surface’s axis of rotation is represented by an axis.

- What is the objective of the mirror command in the sketch, and how do we remove the connection between the original and mirrored elements?

This is a remarkable instrument when working on asymmetrical sketches. The mirror feature can be used within sketches, components, and assemblies. In design, the Mirror command duplicates the illustration about a reference plane. If we evacuate the connection between the original and mirror components, we must detonate.

- How is the arc length measured using CATIA?

We can measure the length of an arc using the MEASURE ITEM command. Occasionally, it is necessary to modify the arc length option if it was not enabled before the modification of the MEASURE ITEM command.

- What is the difference between true dimension and ISO-Constraints?

After machining, the desired dimension is the true dimension. In other words, this is the estimated value after machining. If all the degrees of freedom of geometry are accounted for by a dependable combination of dimensions and fixed geometry, we refer to that geometry as ISO-CONSTRAINED. It is said that geometry is UNDER CONSTRAINED when it has some degrees of freedom.

- What is the distinction between stacked and chained dimensions when the auto constraint option is enabled?

In the stacked dimension, all proportions are measured relative to the reference, while in the chains dimension, proportions are measured relative to one another.

- What are the various conic sections? How many dimensions are necessary to constrain an ellipse, and what is the rho value for an ellipse, a parabola, and a hyperbola?

Ellipse, Hyperbola, and Parabola are the three distinct conic sections. Typically, we require three dimensions: the central axis, the minor axis, and the distance from the origin. Each size of Parabola possesses an RHO value of 0.5, Ellipse includes an RHO value between 0 and 0.5, and Hyperbola possesses an RHO value between 0.5 and 1.
