Hello! Welcome to PTSim, a place for flight simulator scenery design enthusiasts and the home of SBuilderX!

My name is Luis Sá and I got involved with Flight Simulator in 1995. You can use the menu on the left to see my earlier experiences with Flight Simulator. My first scenery was Portugal95 which was followed by Portugal98. Later on I made Madeira Islands and Portugal Terrain. Both run on FS2004. I also wrote a number of tools for Scenery Design. When I finished Madeira Islands in 2003, I started a big project - a tool to generate terrain scenery which I called SBuilder. I used Visual Basic 6 to build it. When FSX came out, I revised the tool using Visual Studio 2005 and I renamed it to SBuilderX. I never made sceneries again but I kept this site to support SBuilderX. Now my hobby is sailing but, from time to time, I revise SBuilderX as it happened in 2014 and 2017. I would like to thank all scenery designers that help me in making SBuilderX a better tool.
