What is the best way to model floors, beams, collumns and floor finishes?
The question is a rather big one... The problem i have concerns all these elements when used together....
Q: On a "Level X" workplane you sketch the floor. Under this floor you model the girders and columns supporting it.
S1: If the floor has multiple layers some UNDER the main structure layer... joining it with a girder will CUT through the girder. There is another problem... the girder is set offset 0 from the level workplane and is the floor is quite thick you get a smaller "actual" girder from what you selected.
(this solution is the worst one and IT HAPPENS BY DEFAULT, and it's impossible to model multiple finishes on the same floor, without actually modeling multiple floors)
S2: If the floor has multiple layers and you model it as multiple independent stacked floors you end up with the walls on the next level attaching to the level and NOT the the floor above the level. You either attach all bases to the "last" floor (in this case the doors end up being lower) OR you start offsetting all girders to be lower (this seems simpler and less intrusive).
(well this is better, if you like your doors not being on the floor, alas it gives some good results as you can have a "structural floor" and multiple finishes floors on top"
Conlusion: I arrived at the conclusion that ALL floor layers MUST BE below or exactly end at the "Level X" workplane. The problem with the doors starting lower than the floor is just too annoying.
Conlusion 2: Well... it is obvious from an architects point of view... that there are actually TWO level systems in a building, one is the Structural, one the floor Finish layer...
So ... the software telling me that for each unique LEVEL, in a building, to get the 100% correct representation i need to either:
ONE
a. Have all girders set to offset UNDER the level workplane to take into account the floor finishes.
b. Have the floor NOT HAVE any layers below the main structural part... or else when joining with a girder it will cut through it with the finish layer.
c. Model multiple floors per LEVEL according to each regions finishes.
OR TWO:
a'. For each real LEVEL you should actually have TWO levels for ultimate control of the finish and structural layers.
IS THERE ANY OTHER WAY TO DO IT?
