✍️ Sample CAD Questions & Answers
1. Which drawing view type in mechanical CAD shows the interior features of a part by cutting through it with a defined cutting plane?
A section view reveals internal features of a part by showing the cross-section along a defined cutting plane.
2. Which GD&T symbol represents 'flatness' on a mechanical drawing?
Flatness is represented by two parallel horizontal lines in GD&T and controls how flat a surface must be.
3. What is a bill of materials (BOM) in the context of a mechanical CAD assembly drawing?
A BOM is a structured table in an assembly drawing listing every part, its part number, description, and quantity required.
4. What is a 'design table' (configuration table) in SolidWorks or similar CAD tools?
A design table is an embedded Excel spreadsheet that drives multiple configurations of a part or assembly by changing dimensions and feature states.
5. Which file format is commonly used for saving 2D CAD drawings?
DWG is the standard file format used in CAD software like AutoCAD for storing 2D and 3D drawing data.
6. Which Civil 3D label style component displays the station and offset of a point relative to an alignment?
Station/Offset labels in Civil 3D annotate a point's position along an alignment (station) and its perpendicular distance from it (offset).
