How can you generate a 16" or 24" low slope roof? The trusses do not build properly. The roof is not thick enough, I'll be out of touch for several hours. Later

Found this https://www.cedengineering.com/userfiles/Design of Com-Ind Guardrail Sys for Fall Protection….pdf The math is a bit over my head though. But if the top rail is stiff that would reduce the tension on the connections. I'm referring to 200# applied to the top rail outward which will flex the top rail & put tension on the connections. The tables for the connectors show the shear capacities but the tension loads will need to be calculated. One way around the tension problem is to put a slip connection in the design.

In our area Simpson is popular in residential, Hilti in commercial. Engineers prefer Hilti from what I see. The Simpson products are available at Home Depot. https://www.strongtie.com/anchoringsystemsforconcreteandmasonry/landing https://www.strongtie.com/strongdrive_exteriorwoodscrews/sd_screw/p/strong-drive-sd-connector-screw

Simpson has some software that may be of some value to you: https://www2.strongtie.com/software/anchordesigner-asd.html Also the tension on the connections can be quite high. https://www.ropelab.com.au/two-point-anchor-calculator/

Well, shear should be no problem for 2ea 1/2" bolts ea end. I assume you have a flat plate bolted to the adjoining materials. The issue is calculating pullout. Pull the middle of a cable attached at its ends & stress gets a bit high. Still epoxy set bolts have a high pull out in filled masonry. Wood is another matter. May need a bolt & washer on that end. Looking at the FDOT 862 railings the railing is attached at the bottom into concrete which is a greater stress. I'll look tomorrow to see if I have anything you could use.

VERY OLD. Back when people were shorter & 30" vanities were being used. About time the database was updated I think. Thanks

So is 72" deemed the standard for wall mount interior fixture heights? That seems too low to me.

My wall mount fixtures are set to 72" & some 68". I changed the default setting (see picture) to 80" but doe not seem to change the light added from the library. Most are set to 72" or less for interior & exterior wall mounted lights. How can I change all (default to) 80"?

FYI, Walls of different types are aligned by Chief via the align with below or align with above based on the outer surface of the "Main Layer": of the wall. NOT the Outer surface of the Exterior surface. This is regardless of the outer covering or the wall thickness. So if you have stucco as an outer layer it must be the same thickness for both wall types.

I know this is an old thread but thought this article was interesting & the "post a sign" solution was surprising to me. http://www.mcgarryandmadsen.com/Blog/Entries/2015/2/12_What_is_the_maximum_length_for_a_clothes_dryer_vent.html

Looking at the pattern it may be quicker to fill the area and then delete the ones you don't want.

Thanks for the suggestion, I'll try to get him to do that. My workaround was to export the PDF to a picture file & use that in Chief. Got the job done.

I have no PLAN file yet. My client is an Architect that creates the preliminary model in sketchup& prints to PDF. He asked me to create a scaled layout on his title block. So I create a CAD detail in a Layout file, scale the PDF to 1=1 then send to layout at the desired scale & print. Eventually, I will create a plan file. Sending to tech support they confirmed that the PDF has an error with the text. Importing to Autocad gave the same error. But I was unable to fix the PDF. The answer appears that the version of Sketchup must be to blame. I'll pursue it on my end. Thanks

When I import some PDF files the text gets messed up, letters out of place within words. The before is a pdf viewer before I import into Chief. The after is what I see after importing into Chief CAD detail in a layout file. How can I correct this?

Thanks for the offer Gerry. What time zone are you in? I use Goto Meeting for seminars attend but use Skype without a camera for clients, share my screen in those cases.

How do you typically load / save Global variables in a plan? I have $roof_TL=40.0 & $floor_TL=55.0 & $wall_ht_1=10.0 & $wall_ht_2=9.333 Also, Can you get the default wall height for a floor?

Gerry, The label option is great, thanks. I can copy & paste, resize and see the results. No issues with a leader staying attached.

Thanks Gerry, What got me in trouble is that I did not set Context correctly. Looks like you can set context to owner & still use owner.area

This brings up another issue, For polyline labels, you only have one choice for label layer? Can that be true? There are so many different uses for polylines and they are on many different layers. You should not be restricted to only one layer for labels. Say it ain't so. PS OK when the pline layer is off the label is off too, but that method does not free up multiple uses for pline labels. .

OK I figure it out. Set Context to OWNER and do not use owner.area just use area.

OK I added the macro to the pline label but Ruby did not like the first line of code. I tried object.area & area but no joy. _area = object.area # tributary area

So would this be the way you would phrase the last variable? str="Roof Load #{_area.round(1).to_s} x #{$roof_tl.to_s} TL=#{ (_area.round(1)*$roof_tl).to_s} PLF" \ + "\nCMU Wall #{wall_wt.round(0)} PLF \n16x8 Foundation 133.4 PLF \n#{plf.to_s} PLF TL on Soil \n#{ psf.to_s} PSF Soil Load"

Thanks for the info Gerry. Much appreciated.

Started reading up on Ruby today in my spare time (not enough of that) but did get my first code to work. I use closed polylines to do some crude load calcs. In this one I am attempting to get the Soil Pressure from the foundation, wall & roof. This is just an approximation based on the tributary area of the roof (40 PSF TL). I use a 1' wide rectangle spanning to the midpoint between bearings to the eve in this case. The code appears to work but I wanted to get some advice of the coding style I used. And any other comment relevant to the coding. One issue I could not overcome was the use of puts which made the code chuck & wobble. Any helpful comments are welcome. I tried to use puts like this but it doesn't work: _area = referenced.area _roofTL = $roof_tl _RL=(_area * _roofTL) plf = (685+123+(_area * _roofTL)).round(1) psf=(plf / 16 / 12).round(1) puts "Roof Load "+ _area.round(1).to_s + "x" + $roof_tl.to_s + " TL="+ (_area.round(1)*$roof_tl).to_s + " PLF" puts "CMU Wall 685 PLF" puts "16x8 Foundation 133.4 PLF" puts plf.to_s + " PLF TL on Soil" puts psf.to_s + " PSF Soil Load" My working code: _area = referenced.area # tributary area _roofTL = $roof_tl # Global Roof Total Load = 40.0 _RL=(_area * _roofTL) ftr_w=16.0 #footer width in inches ftr_h=8.0 #footer heith in inches ftr_wt=(ftr_w*ftr_h/144.0*150) #footer weight in pounds wall_wt=685.0 # 9'-4" CMU wall weight with 3 course stem wall (MOL) plf = (wall_wt+ftr_wt+(_area * _roofTL)).round(1) psf=(plf / (ftr_w / 12.0)).round(1) str="Roof Load "+ _area.round(1).to_s + "x" + $roof_tl.to_s + " TL="\ + (_area.round(1)*$roof_tl).to_s + " PLF" \ + "\nCMU Wall #{wall_wt.round(0)} PLF\n16x8 Foundation 133.4 PLF\n" \ + plf.to_s + " PLF TL on Soil\n" + psf.to_s + " PSF Soil Load"

That's odd, the OP said a SQUARE plan. There are no ridges in a square plan unless two opposite side has a different roof pitch. So are you trying to put a ridge vent on a Hip Ridge?
