ACADuser 143 Posted April 22, 2016 Will Chief handle this with "Floor Trusses" or do you have to modify them yourself? Share this post Link to post Share on other sites
DavidJPotter 315 Posted April 22, 2016 Just as in AutoCAD, and ArchiCAD you use the software's tools to model and emulate all situations. Software doesn't "do" anything, rather you use it to draw and model things. DJP Share this post Link to post Share on other sites
ACADuser 143 Posted April 22, 2016 I see you have to check in the walls structure to "Hang Floor Platform" and "Include Ledger" to get the framing to get the joist to break on the interior walls. Share this post Link to post Share on other sites
ACADuser 143 Posted April 22, 2016 One thing Chief did was to put two extra joist under some walls. How would I stop that? Share this post Link to post Share on other sites
DRAWZILLA 780 Posted April 23, 2016 Turn off auto floor ceiling framing and just delete the joists you want. But you can't turn it on again, so do it when your close to finish. Are you sure there isn't a wall above those double joists? code bearing or not.. Share this post Link to post Share on other sites
ACADuser 143 Posted April 23, 2016 There is a non bearing wall but we don't add a truss for those. I have made some progress. Thanks Share this post Link to post Share on other sites
ACADuser 143 Posted April 23, 2016 Thanks for the suggestions. I'm getting there. How can I get web floor joist? Share this post Link to post Share on other sites
dshall 1503 Posted April 23, 2016 One thing Chief did was to put two extra joist under some walls. How would I stop that? We should be able to specify if we want one or two joist under wall, I do not want to turn off auto framing to achieve this, one day CA will give us this option.... hopefully... we can not do this now.

ACADuser 143 Posted April 23, 2016 Agreed, when you get the design just the way you want it, the client comes back and request moving a few exterior walls & then the auto regen would be a blessing BUT all your changes would be lost. That's why so many people turn auto OFF once it is built the first time. Foundations & Roof are the same way for me. Auto one time only! Share this post Link to post Share on other sites
DRAWZILLA 780 Posted April 23, 2016 Even non-bearing walls parallel with the wall above require double floor joists under them. Share this post Link to post Share on other sites
ACADuser 143 Posted April 23, 2016 No sir, not with 3/4" plywood, just cross bracing and often no bracing at all. 1 Share this post Link to post Share on other sites
DRAWZILLA 780 Posted April 23, 2016 You are correct, it just my engineer for the last 20 years requires it. I would also hate to rely on plywood to hold up wall weight when it could be 20' tall Share this post Link to post Share on other sites
CJSpud 83 Posted April 23, 2016 "How can I get web floor joist?" Alan: Like roof trusses, you have to draw them manually and then make/distribute copies as needed. When you click on the "joist tool" there's an option to draw "floor/ceiling truss" in the drop down menu. You have some control over how the floor trusses build via the dialog. Edit: If what you meant was that you want "I-joists" to display, you just have to make sure that that is what you select for your joist type in the Floor Structure Definition: Share this post Link to post Share on other sites
ACADuser 143 Posted April 23, 2016 Wow your engineer is "one size fits all" kinda guy. What happened to "review the plan & design to the load conditions found"? I think I deleted 16 trusses in this project. None of them were necessary. I guess Chief adds them because it can not determine if they are load bearing or not.

ACADuser 143 Posted April 23, 2016 Thanks Curt, What I wanted was to have Chief auto build the floor system with trusses. It uses TJI's so why not Web Trusses? Another option that would be goo is the swap out TJI's for web trusses globally. No way to to that That I have found. Share this post Link to post Share on other sites
CJSpud 83 Posted April 23, 2016 Yes, those would be nice options to have. You might submit that as a feature request. Share this post Link to post Share on other sites
CJSpud 83 Posted April 23, 2016 It would also be nice to have the option to include a specifically defined opening area for ventilation/HVAC ducting in a floor truss. Seems that several years ago there was a good thread on the subject and I remember experimenting with floor trusses but I am a little fuzzy about what the results of that thread were and/or what others were doing to display their floor trusses for ducting. As near as I can tell right now, all we can do to Chief created floor trusses is edit their dimensions and then do a "force truss rebuild" in order for the edited size to get fixed for plan or other views. I don't believe there's any way OTB to edit Chief floor truss webs (bracing) to create such a chase. Share this post Link to post Share on other sites

No, he just builds better and I agree with him .He reviews every plan, if you only knew. It's good practice. He also teaches the classes at Cal State Long Beach. and checks the engineer tests for licensing for the State of California. Do you think I just go with what Chief gives me for framing, I don't think so. but I do like the double joists under all parallel walls Share this post Link to post Share on other sites
