Preview Questions Draftsman/CAD Technician | Role Specific Skill

Question 1: In technical drawing, what is the primary difference between orthographic and isometric views?

Which action should you take?

Choose only one option

Orthographic views distort the perspective, while isometric views are more accurate

Isometric views are used only for architectural drawings

Isometric views are always drawn in 2D, while orthographic views are 3D

Orthographic views show different views from multiple angles, while isometric views show a 3D representation of the object

Question 2: How do you use Revit's "family" system to create custom 3D components in your project?

Which action should you take?

Choose only one option

By modifying existing families without customizing them

By creating new families from scratch using the Family Editor, ensuring they meet project specifications

By drawing components directly into the project without creating families

By using only pre-existing families provided by Revit

Question 3: What is the best way to represent materials in a technical drawing for a construction project?

Which action should you take?

Choose only one option

Use freehand sketches to represent materials

Rely on labels and ignore visual representations

Apply standardized hatching patterns for different materials, ensuring that the correct patterns and scales are used according to project standards

Use color coding without a key

Question 4: In AutoCAD, how does the use of solid modeling improve construction detail accuracy in 3D designs?

Which action should you take?

Choose only one option

It allows for detailed and accurate representation of physical components, aiding in precise coordination

It reduces the complexity by ignoring smaller details

It simplifies the design by eliminating all dimensions

It focuses on visual appearance, ignoring technical accuracy

Question 5: What is the most effective way to manage project revisions in AutoCAD when dealing with large-scale construction plans?

Which action should you take?

Choose only one option

By using the Revision Cloud tool and maintaining a revision history to track changes

By modifying the original file directly without tracking changes

By discarding old versions after each revision

By keeping all revisions in a separate file and not linking them to the main drawing

Question 6: What is the role of annotations in Revit for ensuring accurate communication of construction information?

Which action should you take?

Choose only one option

They eliminate the need for text and dimensioning in the drawing

They provide essential details such as material specifications and measurements, improving clarity

They are used only for aesthetic purposes, not functional details

They reduce the clarity of the drawing by overcrowding the design
