Starting from scratch I've created a simple two story structure with a 3 car garage on the ground level and a simple one bedroom apartment above. All that I did was create the basic footprint and then draw in walls, nothing fancy, nothing complicated. My structure is 27x40 and is oriented so that the 40' length is across the screen with the top of the screen as North. The default 2x10 joists, though listed as set at 0* are in fact set at 90* as they span the full 40' length of the building (which is just plain dumb for this to be the default since they are much too small, heading in the wrong direction and there isn't an error message indicating too great of an unsupported span).
On top of all of that I have tried every which I can come up with to delete the above mentioned joists and replace them with 2x12's running across the shorter North/South span to no avail. In some sections there are double joists at 90* to one another, in other sections they run parralel to each other and on the landing in front of the entryway there is one running at 45* across the floor.
In addition to ALL of THAT I also can't get all sections of the exterior to update the finish material. On most of the building I could get the log siding I slected but about 25% of the areas just will not change. Individual rooms will also not allow me to change their covering, I can change the entire floor all at once but not seperate rooms and I have attempted to use every option there is available and I've read and applied all the steps listed in the help files and they just won't change! Earlier I had removed the floor above a staircase and now the floor is back and will not go away - again I've followed ALL the steps.
As far as closing the program is concerned I always save on my own and do not rely on the program. When I tried to close after saving I was asked if I wanted to save my changes to "Project 1" even though I had opened just my project titled "3 Car garage" and that's what was still showing on the top bar of the TFP window. I then selected "Save AS" and entered "3 Car garage" and was then told I couldn't because it was already open! Of course it's open because I opened it, this is the ONLY project I have open since I am just evaluating this program with this project. This started out fun but is now quickly turning into yet another futile attempt with lousy programming. I am a video editing professional with many years experience with the entire Adobe Creative Suite of products with special interest in the Adobe Premiere Pro video suite. I am therefore no stranger to complex operations or user interfaces and, so far, am finding TFP to be full of problems and issues.
