10+ Cadd Engineer Interview Questions and Answers

The scale command in AutoCAD is used to resize objects proportionally.

• Select the objects you want to scale.

• Specify the base point and the scale factor.

• For example, to scale an object by a factor of 2, you would enter '2x' as the scale factor.

• You can also use the reference option to scale objects based on a reference length or distance.

• The scale command can be used for both 2D and 3D objects.

Solar panels are devices that convert sunlight into electricity.

• Solar panels are made up of photovoltaic cells that capture sunlight and convert it into direct current (DC) electricity.

• They are typically made of silicon, which is a semiconductor material.

• The electricity generated by solar panels can be used to power various devices and systems, such as homes, buildings, and even spacecraft.

• Solar panels are commonly used in renewable energy systems to reduce reliance on fossil...read more

The fillet command is used in CAD software to create a rounded corner between two lines or curves.

• The fillet command is commonly used in 2D and 3D CAD software.

• It is used to create smooth transitions between two lines or curves by adding a tangent arc.

• The fillet command requires selecting the two lines or curves that intersect and specifying the desired radius for the fillet.

• The resulting fillet is a rounded corner that blends the two selected entities.

• Fillet can be used to c...read more

WSD stands for Web Services Description Language.

• WSD is an XML-based language used to describe web services and their functionalities.

• It provides a standardized way to define the structure, operations, and protocols of a web service.

• WSD files contain information about the service, its methods, input/output parameters, and communication protocols.

• It enables interoperability between different platforms and programming languages.

• Example: WSD can be used to describe a SOAP-based ...read more

The 33% rule is used in project management to estimate the time required to complete the remaining work.

• It assumes that the first 33% of the project takes up 50% of the time and resources.

• The remaining 67% of the project takes up the remaining 50% of the time and resources.

• It helps in predicting the completion date of the project and managing resources accordingly.

Stress strain graph shows the relationship between stress and strain in a material.

• Stress is the force applied per unit area of the material.

• Strain is the deformation or change in shape of the material.

• The graph shows the elastic region, yield point, plastic region, and fracture point.

• Young's modulus, yield strength, and ultimate strength can be determined from the graph.

Resonance can be prevented by changing the natural frequency of the system or by damping the system.

• Change the stiffness or mass of the system

• Add damping to the system

• Use tuned mass dampers to reduce vibrations

• Avoid designing structures with natural frequencies close to external excitation frequencies

Resonance is the phenomenon of an object vibrating at its natural frequency due to the influence of an external force.

• Resonance occurs when an external force is applied to an object at or near its natural frequency.

• The amplitude of the vibration increases as the frequency of the external force approaches the natural frequency of the object.

• Examples of resonance include a tuning fork vibrating when struck, a wine glass shattering due to a high-pitched sound, and a bridge colla...read more

CG stands for Computer Graphics.

• CG refers to the field of computer science that deals with generating and manipulating visual content using computers.

• It involves creating, rendering, and animating images, videos, and 3D models.

• CG is used in various industries such as entertainment, gaming, architecture, virtual reality, and simulation.

• Examples of CG software include Autodesk Maya, Blender, and Adobe Photoshop.

• CG techniques are used to create special effects in movies, design ...read more
