SketchUp: A Simple-to-Utilise 3D Modeling CAD Parcel
There are several 3D CAD software applications bachelor for high-cease, detailed blueprint in the area of technology and architecture. High-powered software comes with a respective price tag which can range from hundreds to thousands of dollars.
Examples of 3D CAD software are AutoCAD, Solid Works, and Solid Edge. SketchUp is a complimentary software package that tin can be upgraded to the pro version (SketchUp Pro) for about $600.
Versions of Sketchup
There are several versions of SketchUp:
- SketchUp Pro, a desktop product which is licenced for use on professional projects. A 30 24-hour interval free trial is available.
- Sketchup Free, an online only product which is free of charge and can be used for home, personal and educational use.
- Sketchup Make, a desktop production which is also free of charge and tin be used for home, personal and educational employ.
- Sketchup 8 and earlier versions. These are free to apply for both personal and commercial apply. However they don't take the aforementioned capabilities of later versions. You lot can download version viii from OldVersion.com
Sketchup eight is perfectly adequate for uncomplicated 3D design of images, diagrams, and graphics for websites and tin can be used gratuitous of charge for home, personal and educational use.
While Google bought the company @Last Software, which originally adult SketchUp, the awarding is currently owned by Trimble Navigation.
Glossary of Terms in SketchUp
CAD: Calculator-Aided Design. The apply of computers and software to create a virtual design. The pattern could be as unproblematic every bit a schematic drawing of an electrical circuit or PCB layout or a more sophisticated 3D model of a building or blithe model of a motorcar. A CAD design can be hands modified compared to a traditional pencil or pen and ink drawing, or a real-earth 3D prototype.
3D Modeling: The process of creating a virtual three-dimensional object within a software package.
Rendering: Adding colors and textures to the surface faces of a 3D object.
Wire Frame: A technique for creating and displaying 3D objects using frameworks of lines. Wireframe images display quicker than rendered images which were important before the days of fast computer systems and graphics cards.
Ray Tracing: Creating photograph-realistic images by simulating the effects of interactions of light rays with objects in a virtual scene.

Designing a Switch: Kickoff With 2D and Extrude
In the video below, I draw a rocker switch.
The design involves cartoon primitive 2nd shapes initially, then "pushing" and "pulling" to extrude the shape into a 3D solid.
Once the shape is created, it can be exported to a JPG file.

I honey the fact that information technology looks and so like shooting fish in a barrel to create those models and can think of many uses for it.
To get a commercial license, to sell the designs is quite expensive though.
Eugene Brennan (author) from Ireland on June 29, 2014:
Yes information technology's quite useful for basic 3D CAD. It doesn't have the sophistication of Solid Works or like fancy packages but is useful for creating graphics for websites.

This is a very interesting article and the tool is fantastic. I still don't know what to apply it for, simply I always see it being used on shows like Flip This Business firm, so it's nice to know that the tool is accessible and gratis.
