About SketchUp: SketchUp or Google SketchUp is mainly a 3D modeling computer program that is used for a broad range of drawing applications used by architects, interior designer, landscape architects, civil and mechanical engineers, film and video game designers also. SketchUp can be getting as a freeware version named SketchUp Make and a paid version with many more extra benefits called SketchUp Pro. SketchUp is software from Trimble Company and there is an online library of free model congregations and 3D Warehouse to which users can add other models; besides that, the program has drawing layout functionality with variable ‘styles’, supports third-party ‘plug-in’ programs hosted on the Extension Warehouse to supply other abilities and enables placement of its models in Google Earth. As SketchUp users are most of architects, designers, builders, makers and engineers etc. who works hard to give a nice shape to our physical world, they need great tools to do the work. SketchUp is in mission to bring their best to produce some great tools for drawing as drawing is the key thing of the SketchUp users. They draw to search ideas, to identify the things and to show other people their work that they do with love and love to build; SketchUp understands it truly and trying to improve their software day by day.

About Extension Warehouse: It is an online resource with various plug-ins developed made especially for SketchUp and these extensions help to add some special tools and features to SketchUp. These extensions can be found for any particular application like drawing or 3D printing and some industry specified tools for architecture, interior design, construction and many more. So basically in this Extension Warehouse people can do the following things:

• Users can search extensions by name or as per the functionality.
• They can also install various extensions with a single click of a button.
• Or users can also control all the extensions from easy-to-use location in the My Extension page.
• 1001 Bit Tools: It is a Freeware with an upgraded professional version. 1001 Bit Tools is a group of tools that simplify the drawing of geometry associated with drawing a structure in 3D.
• Profile Builder: Profile Builder tool can be used to draw any type of walls, railings or fences. After release of the new version 3, Profile Builder can be schemed “Follow Me” on steroids which allows users to put together arrays of geometry that are copied along the stretch of a user-defined path.
• Framer: Though framing is not used often in the models, but if users want to use it then Framer is the best option. Framer is created by the same guy who created Estimator for SketchUp and Framer makes the work quick and easy to add wall framing into the model.
• Vali Instant: There is a LOT to look at here. With extensions that do everything from cladding to curbs, the Vali instant group of extensions adds great looking detail to the model.
• Medeek Extensions: Originally offering a truss layout tool, the extensions from Medeek have increased into a group of tools that will help users to frame a whole structure from foundation to peak.
