Unable to frame floor in lumber, only I joists

Recommended Posts

When I generate the floor framing the program shows I joists, regardless of the fact that I specify lumber (fir studs 16" center) or default, which is supposed to be lumber--according to the reference manual.  This is only true of the first floor framing, the second floor is lumber.

 

I'm sure I am missing something.

 

Any ideas would be helpful, thanks.

make sure you uncheck the default box in the Floor Defaults DBX then check the structure type as Eric shows above ,as even though it may say Fir Framing at the top, the structure type can still show I-Joist and will still be I-joist after you try to change it if you don't uncheck the default box.

Thanks Eric and Mick.

 

This was a tough one and NOT self evident.  When I selected Defaults/Floor Structure, the type (lumber) was greyed out and unavailable to check.  Hometalk 1 jpeg.   I don't know why exactly, but I clicked on the second sizing box (2) under Layer which was set at 7".  When I clicked on that box, the Structure Type then became active and changed to I Joist.  Hometalk 2 jpeg.

 

After I changed that to lumber all is good.  Thank you for the guidance.  Mystery detectives on the job.

your pics seem to indicate you were in the FRAMING Defaults , not the FLOOR Defaults ( though you mention Floor defaults above) ,not sure if that was why it was initially greyed out or not though?

 

FYI  a  7" Floor joist would be a non-standard size  , 2x8 is  7 1/2" and they are no longer used for floor joists unless the span is very short or perhaps for matching up to and existing floor structure . 2x10 or 2x12 is the usual size today.

Mick,

 

Framing or Floor defaults, they are both the same in terms of how the program operates.  I tried it to be sure.

 

I just ran down the basement and measured them--7 1/4" joists.  The house is 1936, so I'm sure that explains it.  We are raising the house, excavating to make our 1/4 basement into a full basement living area, pouring new foundation and setting the house back down.  These are the engineering drawings.

yes the age would account for the 2x8 joists , I run into this at work a lot as many of the homes are 60-100yrs old  here, these days a very rough rule of thumb is not to span more than 1 foot per inch of joist depth , ie a 2x8 would be good for 8 ft max assuming the load wasn't significant , but the Engineer will look at al that as part of the permit process.

 

In some cases you ae right there are sometime 2-3 ways to get the same result , but there are times you need a certain DBX , eg the Framing defaults set for 7 1/4" would give you  that size for ALL joist throughout the house on all levels , but you could also set the 2nd floor to have 2x10 joists if need via the Floor defaults>structure setting.

Have the same problem but can't find what you all are talking about. I have HD Pro 15 and don't even have "framing" under the defaults box.

Beginning to wonder if all of the program didn't download the way it should of (just a couple of days ago) or, more frustratingly, why I paid the extra money for Pro when it isn't giving me anything more than my HD Suite 2006.

Thanks

Used the wrong software title last time. I have Arch 2015 not Pro. That said, the BUILD>FRAMING option is not there for me. If it is, I can't find it. The word "joists" does not show up in the Users Guide and only once in the reference manual under decking overhang. Not sure where to go from here. Not using I-joists.

Thanks

I am not sure HDA has any framing options (see above pdf), it is all autobuild I think except perhaps deck posts and beams and I think it has a locked Floor Thickness like Suite but call CS on Monday to check it is 6years? since I used HDA

 

you have your 30 day return time if it doesn't do what you want so don't panic..... download the Pro free Trial and test it out ...only you can decide if it is worth it.

I'm having problems getting pro 2018 to use lumber instead of I-Joist.  I have went in and set my defaults plus in the build framing I choose wood not I-joist.  Needing to get this fixed so I can finish my material list to send in for bids. Thanks for any help

Read the prior posts above. Those answer unequivocally your question, just read them please. Those answers apply then as now, Pro has not changed that much since it was first published.

1) Please fill out your Signature -- see below.

 

2) You posted in a thread from 2015 -- almost always best to start a new one.

It helps if we know what title (Suite, Pro etc) and version (2014, 2015 etc) you are using. You can add this info to your signature by clicking on your user name at the top right of the page, click Account Settings, then Signature on the left. Doing so makes it always available, and this info is often key to providing a good suggestion

Thanks for the reply.  I just must not be getting it. I have change my defaults to wood etc.. and have followed the example above.  We have tried several things and still not able to get rid of the I joist. I was a one time able to add wood joist with the I joist still in there but my dimensions were not correct since I'm trying to use 2x12 as my floor joist.

Are you rebuilding framing after the change?

 

Post your plan file (in a new thread please) for the best answers.

Update on my situation  I rebuilt my foundation .Went to that layer/level then framed according to the example above. This took care of the I-joist and allowed me to use my 2x12's instead. Thanks for your help
