The interface makes it easy to get up to speed on the basics.

SketchUp's free web-based version has plenty of power, but if you need additional functionality, you have to buy SketchUp Pro-and pay a hefty price tag.

Trimble has enhanced it and developed it further and now offers a slew of related products. In 2012, Google sold the product to Trimble.

SketchUp was originally developed by Google and was one of the greatest free CAD packages ever put on the market. They can also conduct strength and dynamic analyses as well as other engineering calculations, generate construction simulations to assist with scheduling and project management, and complete other complex tasks critical to delivering projects on schedule and under budget.Free feature is web-only with many important features hobbled. Today, CAD programs can be used for 2D blueprints and 3D modeling, as well as the creation of animations and renderings that can help architects visualize building designs for clients. The power and scope of CAD software has grown dramatically since the 1960s, when the first CAD programs were introduced to replicate manual drafting processes. Along with computer aided engineering (CAE) software, CAD programs like Autodesk are extremely important tools for architecture and engineering professionals, allowing them to work and collaborate more efficiently, shortening the design cycle, reducing costs, and improving the accuracy of their designs. Computer-aided design, or CAD, is the use of software to assist with the drafting and design of buildings, machines, and other physical products.
