Very Good foundation, but leaves much to be desired. Controlling the placement of the walls is very annoying, With a lack of an undo button or a way to move the end point of a wall after placing  it makes it so that you have to restart from the beginning. On top of that, selecting some of these things can be a nightmare, the hitboxes to actually select them is frustratingly small. The file explorer is very hard to navigate with the size of the buttons, and the image displayer didn't work at all. On top of that, with a lack of remote placement tools with some objects it makes it hard to model something within a real environment. With a lot of quality of life fixes, this could be really great.
