We used open space for an educational project with a local school district. The software was easy to use, and we were able to get all the information we needed in order to build our building. However, it could have been easier to navigate through the site plan once you got there! It took me some time to figure out how to add walls to the plans. Also, when we first started working on the project, we realized that we needed a new roof truss in one of the sections. When we tried to add this to the plan, it did not show up until after we had built the section, which was too late. This was a great way to visualize what we were building, but I wish the drawings could be edited before we began construction.
