3D Product CAD Software & Tools

Question 1

What type of software is SolidWorks, and what industry primarily uses it?

Accepted Answer

Parametric 3D CAD software used primarily in mechanical engineering and product design

Answer

SolidWorks is a parametric solid modeling CAD tool widely used by mechanical engineers, industrial designers, and product developers for precise 3D part and assembly design.

Question 2

What is Fusion 360 commonly used for in product design?

Accepted Answer

Integrated CAD/CAM/CAE tool for product design, simulation, and CNC machining

Answer

Fusion 360 (by Autodesk) is an all-in-one cloud-based platform combining parametric CAD, mesh modeling, simulation, rendering, and CAM for product development.

Question 3

What is the purpose of 'assembly modeling' in CAD software?

Accepted Answer

To combine individual part files into a complete product assembly and check fit, movement, and interferences

Answer

Assembly modeling allows designers to fit multiple components together, define motion constraints, and detect interference between parts before manufacturing.

Question 4

What is a 'sketch' in parametric CAD software like SolidWorks or Fusion 360?

Accepted Answer

A 2D profile drawing constrained by dimensions and geometric relationships, used as the basis for 3D features

Answer

In parametric CAD, a sketch is a dimensioned, constrained 2D profile (lines, arcs, curves) that is then extruded, revolved, or swept to create 3D geometry.

Question 5

What does 'design intent' mean in the context of parametric CAD modeling?

Accepted Answer

Planning how a model's features and constraints should behave when dimensions are changed

Answer

Design intent refers to structuring a parametric model so that dimensional changes propagate correctly, maintaining functional relationships between features.
