CAD
1. What is CAD Output?
When designs are created or modified using computer-aided design software, the output is known as CAD output. Electronic files requiring printing, machining, or other manufacturing processes are frequently the CAD output. Information about materials, procedures, measurements, and tolerances must be communicated in CAD output.
2. What are the types of CAD?
There are mainly four types of CAD.
- Using geometrical figures and curves, flat drawings are produced using 2-D CAD.
- Designs in three dimensions that may be rotated across various planes are created using 3-D CAD.
- The designers employ 3-D Wireframe and Surface modeling to create the various wireframe patterns and 3-D structure components.
- The 2-D or 3-D wireframe constructions can be enhanced with properties like grain, density, weight, and volume using solid modeling software.
3. Who developed and designed CAD?
Ivan Sutherland created Sketchpad, the first true CAD program, in the 1960s as part of his PhD thesis while attending MIT (Massachusetts Institute of Technology). Because the designer communicated graphically a light pen to draw on the computer’s monitor with Sketchpad’s CAD software.
