I am a professional engineer in the state of Florida. I currently use AutoCAD and have been for 30 years. I do foundations for existing houses that need to be raised out of flood zones. Usually, the foundation is a CMU stem wall on a continuous footer with piers supporting internal spans. Can Softplan do this readily? How about showing rebar?
Also, can I run the same program on my lap top when I travel in my RV?
SoftPlan will run on a laptop, occasional connection to the internet is required. We will have our Florida expert, David Wilson, reach out as he is very familiar with the unique construction methods.
