I have familiarized myself with Cadvilla Professional 11, here is a brief report: I was repeatedly annoyed by how tedious it is to create more specialized elements, such as light shafts. Convenient, on the other hand, is the semi-automatic creation of doors and windows with dozens of details for which you can enter dimensions. Also great is the function that allows you to place 2D plans as photos and adjust the scale so that you can simply draw walls over the 2D plan. The visual 3D quality, however, is not good; everything is very pixelated. Terrible, for example, is the animation of plants. If you use the graphic quality of modern computer games as a benchmark, you will be very disappointed. Of course, you can purchase higher quality 3D object collections for a lot of money. The possibility of modeling landscapes also leaves much to be desired, for example, creating a construction pit. You have to tediously draw double contour lines, etc. A big problem is also the import of 3D-.DXF- files. If a file is not imported well, you cannot even break down the object into individual elements and "name" them, for example, the surface is a door, that one a wall, and so on. I had a freelancer convert my 2D plans into 3D for €100 via a freelancer platform. Unfortunately, the house was imported only as a fixed, unchangeable 3D object. Cadvilla does have many 3D objects, but they either look old-fashioned or are not modifiable. Also, 3D models are missing, for example, of larger devices such as washing machines, heat pumps, ventilation systems, etc., from major manufacturers. Finally, a positive point: You can place photovoltaic modules on your own roof, roughly create neighboring houses (there is a semi-automatic mode for creating houses and roofs), and then let the sun move (sun position data is retrieved directly from the web). This way, you can see possible shadows on the modules. Unfortunately, smart home is not possible.
