Joist and Blocking Placement

When I use the manual joist tool on a deck project, the manually placed joists and blocking always end up as ceiling joists and ceiling blocking.  I just know I am missing something simple, but I can't for the life of me figure out what that is.

It is easy enough to adjust the heights, but then they are on the wrong layers and in the wrong groups.  What am I doing wrong?

a quick guess would be you are drawing them on level 1 not level 0  so it thinks it is a Ceiling joist for level 1 , ie any framing below 0" is displayed on the Foundation level so you need to do the Blocking there too

 

At least that is the one that gets me with the way Chief Works :)

No I did the deck on Level 1

 

Yes but the house must still be sitting on a foundation of some kind right? even if only 1-2ft high. or a Slab?

 

you haven't built one yet , so in essence the House is Floating....

Are the Decks auto built/framed?  or did you draw the decks all manually? and then lower all the Framing?  that would change things....as they are actually seen as Ceiling members or General Framing on the 1st Floor then I think.

I started with autobuilt decks, but the joists were not working out at all.  I had to manually re arrange the joists, and add support for the deck plank ends where they terminated at the border planks.5bccd4bd54cb9_BorderPlankSupport.thumb.jpg.b67c9111a6ba23172d33e232f7674697.jpg

I had to do most of that manually.  The blocking was copied from an original block placed automatically.  I couldn't add any blocking manually using 5bccd533d3e3d_JoistTool.thumb.jpg.3c06dd06a3b1d69f63c7a734be7fddfa.jpg

Anything added was at the ceiling level, and even when lowered to the floor level would not trim properly.   That was the issue.  Since we have been talking I added a blank foundation and now I can see the deck framing in level zero.  The blocking tool works fine.  The beam tool does not work at all, it just doesn't do anything.  The joist tool works but not for deck defaults, for floor defaults.  I was hoping for a manual deck editing tool for framing.

Yeah, I said that later in our back and forth.  I did the blank foundation like you said, and then it worked for the blocking.  Thanks for that. 

 

Okay , I wasn't quite sure where we got to :)

 

Do you normally frame your deck edge with a Single rim-joist?  I think you Contractor will hate you for all that blocking :) 

 

It is usually stronger, faster and cheaper to build if you use a triple rim-joist and perhaps a Fascia (cedar?)

to make up the width at the edge to catch the Border and plank ends.

I will be adding a fascia for sure.  The blocking isn't for the border planks, it is for the biased planks to land on near the border planks.   I don't see any way around it.  The client loves the border planks, so they are here to stay.  As for the deck framing contractor, he will see the design before quoting, so if he has any ideas as to how it can be done better, I will be all ears.  I think that perhaps the center blocking is probably not needed in the narrower decks.

I normally use 2x4 Decking and Borders as it lasts better , and the Triple and Fascia works then , but for 2X6 you could do a double then blocking then another double (Including Fascia piece) perhaps? blocking takes forever , especially when every cut is on a 45° so the extra wood is easily paid for by the reduced labour.

***Looks like a number of your Rim-joists are using LVL at 1 1/8" not 2x10 etc...

      Hello.
       
      I am having issues with an exterior wall. 
      There seems to be a random base plate that is generating a few feet about the first floor level.
      It appears that this plate may also be causing an issue up at the second floor where there is a hole in the exterior wall.
      I try deleting the base plate, but I am not able to select.
      How can I fix this so that the exterior wall generates properly.
      Any feedback is appreciated.
      Thank you kindly.

      I'm having an issue where the framing members for a flat roof (1/4" slope) over a porch are not displaying correctly in the cross section. My default setting for rafter size and the specification in the roof plane dialogue for that roof plane are set to 5 1/2", but it always draws the cross section as a 2x4. If I select any of the framing members individually and open the dialogue box, it says it's 5 1/2". The trusses and framing for the rest of the house all come in correctly. Any quick thoughts come to mind?
       
      also, Is it better to upload a screen shot showing the problem or the whole file on here?

      Using X13. Have "framing default" checked for "Allow Automatic Balloon Framing"...but, as you can see in the picture below it's not working. I have auto framing walls turned on...experimented with the joist direction...didn't seem to have an effect. 
       
      I'm on a MAC...maybe this is a reason? Does anybody know if this new feature in X13 actually works? 
       
      Thanks!

      The lengths of framing members in schedules, i.e. rafters, joists, etc appear to be expressed in fractional inches by default.
      Can that be changed to be expressed in feet and fractional inches.

      I cannot seem to figure out how to make this exposed gable have the same shiplap siding on it that the house has. I built the patio piece by piece using framing members and added roof planes and ceiling planes then added the gable. Now II cannot figure out how to add siding.
