SketchUp

SketchUp formerly Google SketchUp is a 3D modelling computer program for a wide range of drawing applications such as architectural, interior design. landscape architecture, civil and mechanical engineering, film and video game design.

SketchUp is owned by Trimble Inc., a mapping. surveying and navigation equipment company. There is an online library of free model assemblies (e.g. windows, doors, automobiles), 3D Warehouse, to which users may contribute models.

The program includes drawing layout functionality, allows surface rendering in variable "styles", supports third-party "plug-in" programs hosted on a site called Extension Warehouse to provide other capabilities (e.l. near photo-realistic rendering) and enables placement of its models within Google Earth. 

3D Warehouse is an open library in which SketchUp users may upload and download 3D models to share. The models can be downloaded right into the program without anything having to be saved onto your computer's storage. File sizes of the models can be up to 50 MB. Anyone can make, modify and re-upload content to and from the 3D warehouse free of charge.

All the models in 3D Warehouse are free, so anyone can download files for use in SketchUp or even other software such as AutoCAD, Revit and ArchiCAD - all of which have apps allowing the retrieval of models from 3D Warehouse. Since 2014 Trimble has launched a new version of 3D Warehouse where companies may have an official page with their own 3D catalogue of products.

Trimble is currently investing in creating 3D developer partners in order to have more professionally modelled products available in 3D Warehouse. According to the Trimble, 3D Warehouse is the most popular 3D content site on the web. SketchUp designers may visit 3D Warehouse to discover new products or for inspiration when designing their own.
