Q1. How to change 2d to 3d in cad?

Ans.

To change 2D to 3D in CAD, extrude or revolve the 2D shape and add depth to create a solid object.

Select the 2D shape and use the extrude or revolve command to create a 3D shape.
Add depth to the shape by specifying the height or depth of the extrusion or revolution.
Use the loft or sweep command to create complex 3D shapes from 2D sketches.
Apply materials and textures to the 3D object to enhance its appearance.

Ans.

Press operations involve various techniques for shaping and forming materials.

Ans.

Parametric and symbols are design tools used to create and modify objects in CAD software.

Parametric design involves using mathematical equations and formulas to create objects that can be easily modified by changing the input values.
Symbols are pre-defined shapes or objects that can be easily inserted into a design and modified as needed.
Both tools are commonly used in CAD software to streamline the design process and improve efficiency.
For example, a parametric design of a ...read more
