Welcome to SketchUp, Vray and other Resources

Everyone is capable of learning. Learning is part of life. It is a social process of living and bringing everyone to share their inherited resources and discoveries. All of us can influence the life of others through sharing and caring. It is our belief that everyone should be a lifelong learner.

I am putting very important visualization resources and series: tutorials, tips, tricks, VRAY materials and settings, and mini-the-making (MTM) processes.

Sturctural Curvy Roof Tutorial: Simon Bonnet

250px-British_Museum_Great_Court_roofSimon Bonnet allowed us to post this excellent SketchUp modeling tutorial of a complicated roof structural system. Thank you very much Simon.

Simon will share to us on how he will model this structure similar with the photograph on the left using different ruby scripts which are available at You need to register on this site in order to download the following scripts.

Sturctural Curvy Roof Tutorial by Simon Bonnet

This is my following work flow for this tutorial.

Step 1: The Basic Dome Shape




Step 2: The structural framework outline

Step 3: Path Profiles for the structural ribs

Step 4: The structural ribs

Native FollowMe tool is overpassed with this kind of 3D curve job. It makes the shape rotating along the path. Some other solutions exists. I have tried: wikii_FollowMe and keep But in our case, the result does not suit. We can also use Kirill _ 2 Faces + Path following this kind of method: Copy Array Along Path tool...have a look. but this exercise is hard for it too. The last solution to make our shape follow our curves resides in Extrude along a path from 1001bit tools. This one also need to be tamed. For example it absolutely doesn't like to initiate on a vertical line. (29$ seems to be a reasonable price..)


Step 5: Completing the whole ribs system




Once this new ExtrudeAlongPath along these prolonged curves is done, we put the shapes in coincidence two by two for IntersectWithModel and cleaning unwanted. Then the three curves and center references are put together to produce a clean basic roof element component.



Step 6: Modeling the Arches


Step 7: Modeling the Pedestals


Step 8: Here is the complete Model
The dome previously drawn with FollowMe tool is painted in glass material and put in place easily with the centered construction point..


Step 9: Rendering using Kerkythea
