What is the primary purpose of 3D modeling in CAD?
Answer: Generate realistic three-dimensional objects
3D modeling in CAD is used to create three-dimensional representations of objects for engineering, architecture, and manufacturing applications.
Which CAD feature is used to create a 3D model from a 2D shape?
Answer: Extrude
The 'Extrude' feature in CAD allows users to convert a 2D shape into a 3D object by adding depth.
What is the function of the 'Revolve' command in 3D modeling?
Answer: Rotate a 2D profile around an axis to create a 3D shape
The 'Revolve' command creates a 3D object by rotating a 2D profile around a specified axis.
Which file format is commonly used for saving 3D CAD models?
Answer: STL
STL files are widely used in 3D CAD modeling and 3D printing for storing geometric data.
What is the benefit of parametric modeling in 3D CAD?
Answer: Allows easy modifications by adjusting parameters
Parametric modeling allows designers to create intelligent models where dimensions and features can be modified easily through parameters.
Which 3D CAD tool is commonly used for surface modeling?
Answer: Loft
The 'Loft' tool is used to create smooth surface models by blending multiple profile curves.
