-SketchUp is free software for creating SURFACE MOD

-It is developed and marketed first by Google and now it is owne

-It is also widely used all over the world making it an Industry-Software in architecture, interior design engineering & cons

-it is known for being easy-to-use and flexible 3d softw

Before, software for building three-dimensional (3D) mlike buildings, cars, and other stuff was

hard to use

. I meanpeople went to school for years to learn it. And if that wasn’t bmodeling software was

expensive — so expensive that the onused it were professionals and software pirates (peoplebasically). Then along came SketchUp .

Things to Understand before Using Sket

1. You get SketchUp by downloading it from the Inter

2. SketchUp works in Windows and Mac OS X

3. SketchUp comes in two software:a. SketchUp Makeb. SketchUp Pro.


23/38

SketchUp Compare to Other 3D Modeling S

Among the widely available 3D modeling a ketch p is the easiest to use

This software has been suone reason: Within a few hours of launching SketchUp for thyou can get good enough at SketchUp to build something. Y

thick manuals to read, and no special geometric counderstand. Modeling in SketchUp is about grabbing yourmaking something.

Three-dimensional modeling software comes in flavors:

solids and surfaces


25/38

An IMPORTANT Note

An important point to reinforce here is that there’s ntype of modeling software

It all depends on three things:

1. How you like to work?2. What you’re modeling?3. What you plan to do with your model when it’s don
