Is it even possible to do somthing like make a simple hut in swift 3d? …or does all that need to be done in 3ds?
Suit yourself…
I would do it in 3DSMAX cuz in swift it’s much harder to do it…
(almost) Everything is possible if you have the right skills…
You asked * …or does all that need to be done in 3ds…*
No matter where you do it as long as it can be exported to an swf.
It can be done in Swift 3D. First, create a box. Then create a pyramid shape and place it above the box. Color the pyramid red and the box a white or brown. You now have a house. I do apologize for the terseness of this message; I’m in a hurry to help more people!!! 
If this does not help, please reply back and I’ll try to elaborate!
