So I got a building structure worked out.
Loading from data files, very manuverable as in I can have as many buildings as I want, add em at run time, have easy interiors...it works.


I am running into problems picturing how to put a door or an entrance into my building.

I figure, draw a draw as a cube in the building and render it transparent...so it overlaps the building and covers it up for that one spot.

That is obviously not how the profs. do it.


How would I get a door into a square wall.
