I don’t know about this whole Chief is being deceptive argument. Chief is a 3D modelling/designing/drafting program which is what you get. They’re not a rendering software or an image editing software. So to say that pimping up a 3D overview in Photoshop is cheating is a bit of a stretch.

You can draw a half wall and place a ceiling plane over it. That way you have precise placement of the height and slope. The ceiling plane will cut/crop your half wall. No adjusting little diamonds or drawing solids which won’t frame.

To compare look at the different shadows here... Also I think Chief needs to ask for a typo correction on designer’s website unless Chief Architect opened up a new restaurant?... Chef?

I’m way out of my league. From Michael Rust... What at a beautifully designed home and also how it blends into its surroundings. Well done.

That’s a lot closer than I got by a mile. Impressive. Also the pale green used for the cool color seems to have a transparency set to very low that I just can’t duplicate even with the eye dropper on a similar color.

What layer set is your Layout plan using? Check that

I guess I should’ve worded my post as “whoever can reproduce that image and tell us how they did it wins a trip to Disneyland” It’s not so easy. Anyone up for the challenge?

How do they get the shadows to be that pale green? The background then is an image with a gradient created in some photo editing software? Can it be created within Chief?

Looking for more than a guess. I also thought technical illustration and messed around with the warm and cold colours but failed. I was wondering if anyone knows exactly what’s going on?

Hi, how is this achieved? It's the image from Chief's homepage. I love it but can't quite duplicate it. There's a gradient background as well. I've tried with Technical Illustration but can't get it right.

Why are you sending views as image? What do you have on those views? Floor plans? Elevations? Are you creating construction documents? Are they simply 3D views for decorating purposes? If you’re talking about the blurriness before you actually print or print to PDF this is built in to reduce lag, that’s normal. Can you at least post a pic of the problem?

Somehow I remember paste in place would never maintain the floor level or elevation and you could freely past items on another level. Now it seems the z coordinate is also carried over and this does not work as intended. Especially if you’ve ever tried copying a staircase from one level and pasting it to another. Doesn’t work. Even if automatic heights are not checked. There seems to be a problem. (Could also be I’m the problem)

Bonus tip: to find the pitch ratio in degrees use the atan function example atan(6/12) = 26.56° If you have an iPhone turn it sideways and use the trig calculator, I’m sure there’s something similar on Android. Using google on the computer always messes me up as it did here to a couple of guys.

Yeah, the 1/16th fascia was just to help me see what was really affecting the issue I was having with my flat under fascia problem. It doesn’t affect the roof height anyway. Only the eave structure. Thanks again for the help!

Ok I'm getting pretty good results with a simplified version of the formula and I'm using the Chief recommended approach to use Trusses (no Birdsmouth) tan(atan(6/12)) x (21.5) = 10.75 where 6/12 is the pitch and 21.5 is the overhang with no adjusting. and to get my flat soffits I have to adjust the eaves like this in the structure tab... The soffit surface comes just under the top plate which is actually how it is built on the field since the carpenters nail the soffit to the underneath of the extended bottom chord cantilever. I think we've go it.

I’m lost. There’s no rhyme or reason to this. The formula does not consistently work. I don’t think you guys are trying it for different values. Or maybe you’re not rebuilding 3D after to see that although the formula gets close it’s not mathematically precise and not building the model as desired. We need a road map from a programmer at Chief. We’re pissing in the wind here.

It's close but no cigar. using the formula: tan(atan(8/12)) × (24 - 1.5 - 0.75) = 14-1/2" and using automatic "birdsmouth cut" instead of "raise from plate" here is the result. and if you try various other pitches/overhang combinations the results vary even more. Also I can't get "flat under eave subfascia" anymore for some reason. Raise off roof study.plan

So the formula will be: tan(atan(8/12)) × (24 - 1.5 - 0.75) where: pitch = 8/12 overhang = 24 fascia = 0.75 subfascia = 1.5 Just tried plugging 6/12 with 18” overhand and I get the wrong value of 7-7/8” instead of 5-3/8”

I’m not at my desk now but I will plug in a few different values and get back to you. Thank you so much for sticking in there. I definitely owe you a beer at least! thanks either way

If I could even select all of my roof planes and simply enter the top of fascia then that would work as well. Unfortunately you have to select each plane one at a time to change the top of fascia value because if you select all the planes then Chief greys out the top of fascia value. Too bad

I tried the formula: for 6/12 pitch which is 26.56° and 18” overhang: Using your formula tan(26.56) X 18” = 9” raise off plate BUT in reality the value is 5-3/8” Then you said to try subtracting the top chord of 3-1/2 which I'm assuming that you're just taking a stab at the arithmetic of 9"-3.5"=5.5" so that got us close to the real value of 5-3/8" however that isn't the math behind this calculation because the chord thickness doesn't really affect the height of the eave. And using the formula for a pitch of 8/12 and a 24" overhang produced even wilder results. Formula no work. BUT, I think you're on the right track. There's just one more variable needed and we don't have it and there doesn't seem to be a way to produce it in advance of the calculation. And that is the vertical height from top plate to the baseline. (I'm guessing here to) If anyone knows of a way to calculate that value then I think we can figure out the math. I had called Chief on this a few years back and they had told me to plug in different values and take cross sections to find the raise off plate value and to make a table with the most common pitches and overhangs that I use on a regular basis. I use 4 different overhangs, maybe 7 different pitches on a regular basis. I was hoping by now someone might have figured this stuff out.

Omg I’ve entered a world where reality and fantasy blend into one alternate universe. Chief’s roof dialogue box is the portal. Beware.

Change pitch and overhang and you won't have eave level with top plate.

It worked for 6/12 with 7-1/4 top chord but didn’t for other variations. It’s really dependant on pitch angle and overhang. I think the other variable that we need is Chief’s Baseline height from top plate. That vertical distance as explained in the help file under the “Baseline” definition in the Roof Planes section.

Regardless of structure, the software is using a top secret variable in order for it to cut out the trusses so that they don’t interfere with the ceiling height. What is that variable? If we know that then a formula would be easy to figure out.
