.... R302.12 Draftstopping. In combustible construction where there is usable space both above and below the concealed space of a floor/ceiling assembly, draftstops shall be installed.... I do not think there is usable space above the mansard so why are draft stops required at mansard attic but not in the attic on the right picture.

BTW, David Michael is the original video king. I learned a ton of stuff from him back in the dark ages.

Let me see if I can sum this up. We do not need drafts stops in attics because there is an attic access. We do need drafts stops in mansards because the mansard attic is an enclosed space without an access. If I provide an access to the mansard attic area, I do not need draft stops. Would anybody disagree with what I just said?

I saw this with commercial projects years ago. This is a two story house. Why don't we put draft stops at 10' in our house attic?

3 of the most experienced users and we do not know for sure. My client just got nailed, he spent money and time putting them in, and why? I do not know. He will ask the inspector to cite the reason, I will let you know.

I have a 20' x 20' square building with a flat roof. I have a mansard roof around the perimeter of building on all 4 sides. Do you think the attic area within the mansard needs to be fire blocked every 10 feet. If not every 10 lineal feet, then is it fir every 1000 sf of attic area.... inquiring minds want to know this important stuff. I want to know it because I do not have a life and the darn inspector is asking for it.

Thanks Mickey for the info. I will double check tomorrow. At one time, back during the Stone Age, I think they had to be on when initially sent to layout.

Stop it Richard, just stop it, you are making things too easy. ...... But wait... suppose you have a wall mounted light fixture hanging on a wall that is being demo'd.... that wall mounted light fixture might seek out the closest wall... therefore being incorrect...... maybe I am over thinking things.

To restate what Dermot said, I think the key is you must have the ref set on when sending to layout.... if you do not see the ref set in layout, it may be because it was sent to layout initially without ref sets on. I know, I repeated what Dermot said , but sometimes things need to be stated twice and differently to get the point across.

That is so true.... I just got a set of plans for a project, it is about 4 pages long, we are going to do a second floor addition, when all is said and done, I will probably have about 20 pages for this project.

Perfect, so you have a split level, first level at 0.0, half level at 4.5', next level at 9.0'...... where does the 4.5' level go? On the bottom floor or the upper floor. I understand if the project is a box on a box, but how to handle the variables? This ties into Michaels question about what if the project is a single pour..... honestly, I do not have the perfect answer, I deal with it on a case by case basis, the point being, there are many unique configurations that I need to deal with. A rhetorical question, you do not need to answer......

Uh, yeah.... it is amazing how much more our plans need to be details compared to 20 years ago. Yes you must show second floor overhangs on your first floor for no other reason to show that are the required distance from the property line. I have a feeling the folks in Indiana do not need to provide as much detail as the nit wits in California need to provide. And I include Perry and myself in the nit wit category. Perry, it never ends does it? There is always something new that we must provide........... not only do we have to provide it, but we have to figure out the best way to present it so we do not get a comment questioning how we should of provided whatever we should of provided in the first place because somebody needs to show how smart they are in regards to what they know and blah blah blah....... Back to the topic, I am like Perry, I use Ref Sets for every set of plans... PERIOD.

I don't know why, it is a mystery to me......

I am not sure what this means. Anno sets and ref sets are two different animals, something I am sure Joey knows. Maybe he meant he handles this with Layer Sets rather that ref sets, however, again I think there are different reason to use. I use both layer sets and ref sets to display what I need. But to give Joey his due, he does basements and I am sure he has done enough to know how to get what he needs.

Yep, I did a vid too. I think you can put a bedroom on level 5 with a floor elevation of 0.0,and then you can put a living room on level 1 with a floor elevation of 50', and it will show correctly in 3d with the living room at a higher elevation than the bedroom even though the living room is on level 1 and the bedroom on level 5.

....... Thanks, good explanation.

Well, I wish I could follow this, I wish I could follow my own post, I am sure you know how it works, but I am not sure if what you said or what I said actually helps anybody understand why we use different line weights...... The Great Glenn Woodward could probably explain this...... The point being, what settings would we change to have super thick lines or super thin lines that are not dependent on the layer line weight..... well, I think I just confused everybody.... sorry Graeme, I am trying to get to the bottom of what controls the line weights...... OTHER THZN THE LAYER.

This is an interesting topic. For my 1/4" floor plans my line weights go from 10-35 For my 1"=10' site plans, my line weights go from 35-120 or more So why the disparity? I think I know, but it would be too convoluted to explain. This sounds like a good workshop topic.... at least for me... I set up my stuff 10 years ago and haven't changed, I doubt if I could do it again. Point is, I think the greater the range of numbers, the more flexibility. I liken it to Farenheight vs Celsius..... farenheighttterrrr seems to be more exacting since there are more degrees from freezing to boiling in farenheighttttt3r3r vs Celsius..... I wish I knew how to spell farenheightering.

I agree with Larry, Kevin apparently does not understand how to control floor joist direction, spacing , and depth. This can all been done fairly simply. The issue is controling different WIDTHS, this is where manual work needs to been done.

Lew, do you really think converting his house to a symbol will solve his issue?

Hello, why doesn't CA realize a lot of us work this way? Why not have the option? I have been asking for this for 6 years now.

Nuts.

I suppose since I had never realized this, I cannot have 2x floor joists under one room and 4x floor joists under another room... without manually drawing them in, is that so? I can control the spacing and the depth but I cannot control the width? Is that so? I believe the width is controlled in the floor dvx and so there is only one option for the width. WOW, that is not good. Not a killer but a bit limiting.

Open wall and uncheck floor hangs on wall

Some walls are backwards and they don't have finish on one side.
