16 Best CAD Software in 2021

What is 3D CAD software: Computer Aided Design Software Definition

3D CAD software is a three-dimensional computer-aided design technology that is used by engineers and architects to manage technical along with design documentation. CAD design software uses multiple points in 3D to help professionals visualize an object. 

Precise technical drawings with unprecedented visibility is possible with CAD design software. All possible because of the application's inbuilt documentation and drafting tools. 3d CAD modeling solutions are also deployed by machinists, engineers and product designers for advanced simulation and high-quality generative designs. 

The best CAD software with its robust freeform modeling, direct editing and parametric tools aid in both multi-CAD translations as well as industry-standard drawings. Here are some of the general purposes filled by paid and free 3D CAD software solutions:

• Maintaining essential design and manufacturing databases
• Enabling collaboration and communication with teams and clients
• Precision and accuracy in designed drafts
• Altering and editing designs easily
• Efficiency in preparing 3D/2D models and drawings

Design professionals find CAD drafting tools most useful for reducing errors associated with 3d modeling. For instance, the best CAD software for mechanical engineers helps with identifying structural flaws in building designs so that they can be corrected before the same get implemented for construction purposes.

Must-Have Features of 3D CAD Software - Free & Paid

Data management, technical documentation or electrical design, perform these tasks easily with 3D CAD modeling software. Here’re some of the other 3D CAD software features:

• Drafting tools

Drafting tools within 3d CAD software are mostly used in architectural drawings such as floor plans and house spaces. Smart symbols, scaled plans and object placement are the important options built-in within drafting tools to serve the purpose.

• Automated tape measurements

Taking measurements with 3D CAD software is easy because of its inbuilt ruler options. Setting up metric and imperial measurements, document scrolling and panning or just setting up a page ruler, all is easy with computer-aided design software.

• Smart dimensioning

Blueprints and drawings require accurate dimensions for the right final design. Best 3D CAD software solutions thus offer snap tools for locating tangents, automatic alignments, and identifying object centers/perpendiculars.

• Auto shaping

3d CAD software lets you add shape to all designs in few simple clicks. These shapes can be resized, ungrouped, recolored and unlinked easily using CAD drafting tools.

• Assembly modeling

Assembly modeling is a technique most useful for putting together design tasks. This feature is most important for developing product concepts. You can use popular CAD design solutions for doing assembly modeling.

• Drawing

This is perhaps the primary and most important function of CAD design software. You can create precise initial designs using 3d CAD modeling techniques like visualization, documentation, and simulation so offered by CAD software. 

• Rendering

3D CAD rendering lets you create 3D raster images that in turn provide a clearer version of the designs that you are going to make. Such renderings are important for checking the impact of shadows and light.

• Coding & classification systems

Coding and classification systems help professionals pull out particular designs from their related classifications. This feature is important because it saves you from the hassle of drawing a new design. 

• Standard drawing templates

Manually maintaining accurate dimensions is cumbersome if done without 3d CAD software. Here you can prepare standard templates with details of dimensions, etc. so that they can be both used and circulated amongst teams for use. Standard templates also mean that you don't have to create dimensions for a new design from scratch.

How to Find the Best Computer Aided Design Software for Beginners

Most used CAD software provides support for various collaboration, design and data management tools. Along with these, there are certain factors you need to keep in mind before buying a CAD drafting solution. The most important factors are:

• Determining your specific requirements: Determine first whether you want a solution that supports on-premise deployment or is cloud-based. Second, understand the purpose of getting CAD design software. It could be that you have 3D CAD requirements or multi-CAD/2D CAD projects to work on.
• TCO: TCO or total cost of ownership includes all costs starting from direct or procurement costs besides maintenance, upgrade and other such indirect costs. TCO helps determine such indirect costs associated with buying a product rather than just the procurement price. This would ensure that the 3d modeling solution fits your budget.
• Efficient 3d designs: The best CAD designing solutions let you draw even the most complicated designs in a few simple steps. Before buying such an application, check the efficiency of its features. For example, if you are into the business of designing stylish products then look for tools that offer support for continuous curvature and freeform surfaces. 
• Drafting tools- CAD software should help in making drawings because information like critical dimensions, surface finish specifications, and tolerances aren't clear in 3D models. Therefore, check for such drafting tools that would help with lettering, tolerances, parts and dimensions.
• Ability to revise designs- The ability to revise designs reduces time spent on inspections, estimating costs, machining and testing.
• Assess the package & vendor support: Good vendor support means a vendor is willing to help its customers with training sessions, user groups and general help for integrating 3d designs with the manufacturing process.
