3D Product CAD Software and Tools

Question 1

Which CAD software is most widely used for mechanical and product design engineering in the US?

Accepted Answer

SolidWorks

Answer

SolidWorks is the dominant parametric solid modeling CAD platform in US product design and mechanical engineering, used for detailed parts, assemblies, and drawings.

Question 2

What is Fusion 360 primarily used for in product design?

Accepted Answer

Integrated CAD, CAM, and simulation in a single cloud-based platform for product and industrial design

Answer

Fusion 360 combines parametric modeling, free-form sculpting, CAM toolpath generation, and FEA simulation in one tool, making it popular for small teams and startups.

Question 3

What is the primary purpose of Rhino 3D (Rhinoceros) in product design?

Accepted Answer

NURBS-based surface modeling for complex, free-form industrial and product design

Answer

Rhino specializes in NURBS surface modeling, making it the preferred tool for industrial designers creating complex organic and precision curved product forms.

Question 4

What distinguishes Keyshot from other 3D software in the product design workflow?

Accepted Answer

It is a dedicated real-time rendering application optimized for product visualization

Answer

Keyshot is a real-time ray-trace rendering engine used specifically for product visualization — creating photorealistic images and animations from imported 3D geometry.

Question 5

What is 'GD&T' and which type of technical drawing uses it?

Accepted Answer

Geometric Dimensioning and Tolerancing — used on engineering drawings to define part geometry, size, and allowable variation

Answer

GD&T is a symbolic language on engineering drawings that precisely defines the allowable variations in form, orientation, and location of part features for manufacturing.
