10+ CAD Technician Interview Questions and Answers

Dynamic blocks in AutoCAD allow for easy modification of block geometry and attributes.

• Create a block with dynamic properties using the Block Editor.

• Add parameters and actions to the block to make it dynamic.

• Save the block and insert it into your drawing.

• Modify the block's dynamic properties using the Properties palette.

• Examples of dynamic block properties include stretch, rotate, and visibility.

• Dynamic blocks can save time and increase efficiency in drafting and design.

A cross section of a highway shows the vertical profile of the road, including the pavement, subgrade, and any other layers.

• Include the pavement layer, which is typically made of asphalt or concrete

• Show the subgrade layer, which is the natural ground or prepared foundation

• Indicate any additional layers such as base course or subbase

• Include any drainage features like ditches or culverts

• Label the dimensions and elevations of each layer

• Use appropriate symbols and annotations to ...read more

Drains are typically provided on the sides of the highway to collect and divert rainwater and prevent flooding.

• Drains are usually located on the sides of the highway to collect rainwater

• They are designed to divert water away from the road and prevent flooding

• Drains can be in the form of ditches, culverts, or catch basins

• The location and design of drains depend on factors such as the slope of the road and the amount of rainfall in the area

Shared parameters are parameters that can be used across multiple elements or families in a CAD software.

• Shared parameters allow for consistent data management and reporting in CAD projects.

• They can be created and managed in the software's parameter settings.

• Shared parameters can be assigned to various elements or families, enabling them to share the same parameter values.

• For example, a shared parameter for 'material' can be used in different furniture families to specify the...read more

Sub Modify Elements is a command in CAD software used to modify specific parts of a larger object.

• It allows users to modify specific parts of a larger object without affecting the entire object.

• Users can select the sub-elements they want to modify and apply changes to them individually.

• This command is useful for making precise adjustments to complex designs.

• For example, if a user wants to modify a specific feature of a building design, they can use Sub Modify Elements to isol...read more

Dynamic blocks in AutoCAD are customizable and flexible blocks that can be easily modified using parameters and actions.

• Dynamic blocks allow you to create a single block with multiple variations.

• They use parameters to define the geometry and behavior of the block.

• Actions can be added to the block to modify its appearance or behavior based on user input.

• Parameters can be associated with grips, allowing users to easily manipulate the block.

• Dynamic blocks can be used to create d...read more

I am proficient in AutoCAD, SolidWorks, and Revit.

• AutoCAD: Used for 2D drafting and 3D modeling.

• SolidWorks: Used for mechanical design and simulation.

• Revit: Used for architectural design and building information modeling.

To draw a line in AutoCAD, use the LINE command and specify the start and end points of the line.

• Open AutoCAD and select the LINE command from the Draw panel.

• Click on the starting point of the line in the drawing area.

• Move the cursor to the desired end point and click to finish the line.

• Press Enter to complete the line drawing.

• You can also specify the length and angle of the line using specific commands.

A line is a single straight path between two points, while a polyline is a series of connected line segments.

• A line is a single entity with two endpoints, while a polyline is made up of multiple line segments connected end-to-end.

• Lines are simple and can only be straight, while polylines can have multiple segments and can be straight or curved.

• Polylines are often used to represent complex shapes or paths, while lines are used for simple straight connections.

• In CAD software, l...read more

CTB stands for Color Table File. It is a file format used in CAD software to define the colors and line weights of plotted objects.

• CTB files are used in AutoCAD and other CAD software.

• They define the color and line weight of plotted objects based on the assigned color index.

• CTB files are often used in conjunction with DWG files to ensure consistent plotting.

• They can be customized to create unique color schemes and line weights for different projects.

• CTB files are typically sa...read more

Layers in AutoCAD are used to organize and group objects within a drawing, allowing for easier editing and management.

• Layers help to control the visibility, color, linetype, and other properties of objects in a drawing.

• Objects can be assigned to specific layers, making it easier to select and manipulate them individually or as a group.

• Layers can be turned on or off to show or hide specific parts of a drawing.

• Naming conventions for layers can help to keep drawings organized an...read more

Block is a single entity in AutoCAD, while wblock allows you to save multiple blocks as a separate file.

• Block is a single entity that can be inserted into drawings.

• Wblock allows you to save multiple blocks as a separate file for reuse.

• Wblock is useful for organizing and managing blocks in AutoCAD projects.

MNB and ROB are bridge types with different span arrangements.

• MNB (Multi-Beam Network) bridges typically have equal spans between beams.

• ROB (Road Over Bridge) bridges can have varying span arrangements depending on the road and railway alignment.

• Span arrangements for both bridge types can be determined based on factors such as traffic volume, load capacity, and site conditions.

A girder is a large and horizontal support beam that is used in construction to support heavy loads.

• Girders can be made of various materials such as steel, concrete, or wood.

• The type of girder used depends on the load it needs to support and the span it needs to cover.

• Examples of girder types include I-beams, box girders, and truss girders.
