Balinese House in Watercolor painting

This is a sketch drawing of a varandah of a Balinese house. This is a watercolor painting of an outdoor view that I made during my stay in Bali.. Watercolor is one of the most difficult painting medias yet it was frequently used by architects to visualize their design concept to clients. Today there are a number of BIM softwares that can render a 3D model of a house or a big building.
The use of watercolor as a manual rendering tool is decreasing with the development of more sophisticated BIM software that can visualize design ideas in 3D and render them in more realistic views.

Balinese Architecture
I created the above drawing only as an artistic expression not for architectural purposes. But if you are really interested in Balinese style houses, please, order and read the following book:

Manual Drawing
However, the use of drawing pencils and watercolor painting are still being used by some designers due to their flexibility and ease of use particularly on models that have unique forms and complicated 3D curves that cannot easily be drawn in CAD software. Such curved models include wooden statues, carvings or relief on the legs of chairs and pillars of houses, or hull form of a ship. Although most of the BIM softwares can be used to create models in 3D environments, only CAD software with NURBS features that can visualize such complicated curved forms easily.
For architectural design, the most recommended software is Google Sketchup. Google has provided the free version of the software that can be downloaded from the official website of sketchup. In addition to the free edition, the Google Sketchup Pro 8 which can be obtained for 495 US dollars has got more features that designers and architects can use to model their design concepts in 3D environment. In version 8, Google introduced solid tools that greatly enhance Sketchup as a powerful BIM software. Google Sketchup can be used by naval architects to model ships and boats in 3D if special plugins such as the bezier lines are installed into the software. by Charles Roring

Yacht Design in 3D View Modelling

Sailing yacht model that is presented below is a boat that is propelled by wind and to certain extend by a small diesel engine. Today, ship and boat design software can be used to visualize the hull form of a yacht in 3D view. Ship designers or naval architects can use the available hull forms and modify them according to the principal dimension of the new hull which they want to design or create from scratch. Please check the official website of to get download the demo version of the software.
In fastship software, the visualization of the hull of yacht initially is given in half-breadth view. It can be confusing for the customer who has ordered the design. First time user of Fastship can easily present a complete hull form of the yacht by pressing Reflected Image button in the toolbars to show both sides of the hull form.
Another naval architecture software that is available for free is Delfship. Ship or yacht designers can download the fully functional free version from its official website at Although designing yacht can now be done by computer software, a comprehensive knowledge about hydrostatic and hydrodynamic principles of yacht have to be studied by designers to ensure that the marine vehicles which they design are safe and stable. Yacht Design According to Perry is a recommended book for anybody who wants to design, build or buy a yacht.
To see the effect of the reflected image, we can rotate the hull of the sailing yacht by pressing the spin button and then with the computer mouse we bring the cursor to the hull and begin dragging it to left or right and up or down. Now, look at the above picture of the yacht that I have rotated to the left. The main deck covers the whole top area of the hull. This sailing yacht model has got a long vertical keel or fin to balance the wind force on the sails and mast of the yacht. by Charles Roring
