Explore the World of 3D CAD

There’s a buzz about 3D CAD in the market. When it comes to designing ideas, visualizing concepts and simulating designs how they will perform in a real environment, 3D CAD comes into the picture. In many industries, due to an explosion in 3D Printing technology, 3D CAD Software is becoming the de facto product design tool.

What is Computer Aided Design (CAD)?

Computer- Aided Design is generally the creation, modification, analysis and optimization of design using computer systems. It is used in electronic design as well as mechanical design which are commonly known as electronic design automation and mechanical design automation. CAD is used in various applications including automotive, shipbuilding, aerospace, industrial, architectural design, prosthetics, and much more.

Engineers, construction professionals, and architects use 3D CAD Software to design schematics for three- dimensional objects. CAD software increases the productivity of the designer, improves design quality, and improves communication through documentation. It is mainly used for commercial, industrial or residential buildings and automobiles. The best part about 3D CAD designs is that it takes less time while reworking on the design as compared to traditional drafting.

Factors which should be considered before choosing 3D CAD system:

  • Efficiency in making 3D Design: The 3D CAD system chosen should offer the best value along with all the technical capabilities. It should be capable enough to make all the designs in fewer steps which will save time and offer cost advantages.

  • Information flow: The CAD system chosen should have the ability to import files from other systems. The CAD system should support the international standards such as STEP, IGES, VDA, and IDF. The tools should be evaluated for fixing damage to imported shapes.

  • Drafting Tools as per your standards: The CAD system should be able to make drawings to your current standard for dimensions, tolerances, lettering and part lists. Drawings should be able to export in formats such as PDF, DXF, and DWG.

  • Reduces design time, testing, machining, cost estimating and inspection: The CAD platform should have extensive and well-documented API’s. Such API’s can be easily integrated with your CAD system and that too at low cost.

  • PDM for Data Management: It’s very important to manage the data through Product Data Management (PDM) software integrated with CAD. PDM help designers to re-use the existing parts instead of re-inventing them. It also helps in generating a list for cost estimation and feeding data to MRP systems.

Advantages of 3D CAD Software:

There are several advantages associated with 3D CAD software. They are:

1. Product Design at faster rate
2. Automate design process
3. Effective communication with customers and suppliers
4. Effective internal design reviews
5. Generation of virtual prototypes
6. Incorporate design changes during prototyping
7. Enhanced speed and precision of production
8. Designed data management
9. Standardize details and drafting practices
10. Test designs and validate them
11. Reducing costs by eliminating problems and errors.


The explosion of 3D printing technology has attracted a large number of new designers into the market for 3D CAD software. 3D CAD technology is here to stay for a long time and has become the accepted medium for designing products, tools and manufacturing equipment.
