I have recently picked up SketchUp again as a tool for layout design. I had previously considered CadRail and 3d Plan-It but instead opted for graph paper for the initial planning iteration. While trying to better communicate about building my model railroad on the blog, I have found SketchUp to be quite useful. Here is the latest work I have completed while preparing to add the plywood sub roadbed to the latest bench work section.

I will draw a grid and print the drawing from above to assist with cutting the plywood. Dealing with elevation change is very difficult and I have not yet mastered that yet. Currently the drawing illustrates a constant +6 (54″) elevation along this section. Google has added the landscape tools into the free version so I am looking forward to trying that functionality out as well.

I have also began experimenting with structure mock ups and design using the tool. You can even create a walk through to visualize the layout design from multiple angles. The tool is free as in beer, the documentation is great including video tutorials, and makes is a great addition to my modeling tool box.
