First look at a polygon floor using MPC floor trusses.



However the following the items still need attention:

Gable trusses
Ribbon boards
Multiple chase locations

After a full day of tinkering and refactoring a bunch of the original floor truss code I think I now have the multi-chase algorithm working:



Note how the chases all line up even though there are five or six different truss profiles within this assembly. I still need to create the web generator between the central sections of the truss profile, there is quite a bit going on here. I am still a few days out from completing the programming and then another two or three days of testing and further debugging.

Just when I think I'm ready to move to the gable trusses and the ribbon boards I realized I hadn't checked top bearing trusses. Spent most of yesterday and this morning sorting this truss geometry out:



I've spent a good bit of time devising the algorithm that inserts the webs into these trusses and overall I think it is fairly successful (and believable) however I will be the first to admit that it is not quite perfect. Also I am little unclear on how to deal with specific situations. I guess I should spend some more time studying different Mitek and Alpine floor truss examples to cement my knowledge on the exact way all cases are handled (even though there is probably some variability in certain instances).

Looks like I'm about 95% there with floor trusses:



The only issue appears to be what happens when ribbon boards are enabled and you have an inside corner as shown. I probably need to add in some additional logic to eliminate the slot for the ribbon board in these cases.
