Are there houses that even professional software cannot depict?

Hello.

It seems to me that in every house planning, whether free like "Sweet Home 3D" or paid like "Architekt 3D," you are always given ONE level of ceiling and floor.
With Architekt 3D you can see that in a video on YouTube.
Can that really be true? Does it happen that rarely?
Attached is an example of how something like that can look.

Sure, a 3D software like Sketchup could somehow represent that, but it is not house planning...

With the software I use, that would be possible, with [SweetHome3D] I think so too, but you would have to trick it – with both and model intermediate levels. So it should work, but it’s not exactly nice... and I am not 100% sure about [SH3D] either.

Yes, I had already thought of that, but just look at the sketch. If I make everything in the basement 264 cm high and screw a "plate" to the ceiling everywhere except the hobby basement, I no longer have stairs going up to the sleeping area. Also, you have to go higher into the house. Of course, the house already stands; it would no longer correspond to reality.

If I then add a landing in the sleeping area so that it is again higher with stairs, the whole area is too high. For example, compared to the terrace, etc. at the back.

I don't know how one could "trick" that, or have I overlooked a possibility? If software can't do that, not even the professional ones, then that would not only be unprofessional for professional software; it would at least have to allow placing two houses directly wall to wall in one plan to "trick" it. Then you could plan the height differences seen in the picture as two houses. If you stand on the roof, the rear part is also higher than the front. With its own surrounding roof shingles, etc. Like a second house. The real adjacent house is on the same level.

SweetHome3D is certainly not professional software. I use cadvilla, I would classify it price-wise rather in the ambitious hobby range (€50-€250), professionals certainly pay in the four to five-digit range. With CADVilla it already works in the smallest version. You can design several building parts as individual buildings and assign them their own floors. So it works quite straightforwardly, but the software has a different learning curve than SweetHome3D. I modeled the entire terrain on my side (from the contour lines of the cadastral maps) in order to capture the elevations of the neighbors, the street, etc., and to be able to plan the house entrance/carport area (where steps come, where a ramp, where L-stones come to the neighbor, etc...).

So a comparable price to Architekt 3D, which also ranges from a few tens to around 300, I believe.

As a tip. There are a few (many) YouTube tutorials on CADVilla that show the modeling of terrain, underground garage entrances, etc. You get a pretty good impression (in my opinion) of what is possible and how it works without having to buy or install anything. The narration is quite amusing, no idea what the speaker took [emoji6]
