I have never been successful in breaking a 3D Molding Polyline, so I've always assumed it's not possible.

Agreed. In my experience this is true only if it's foil-faced, otherwise, most unfaced products are considered a Class I vapor retarder (vapor semi-impermeable, 0.1 to 1.0 perms) at thicknesses of greater than 1 inch, and a Class II vapor retarder (vapor semi-permeable, 1.0 perm to 10.0 perms) at thicknesses of one inch or less.

Perhaps in Alaska where you encounter subarctic and arctic conditions, but in my opinion, an "intelligent" vapor retarder is suitable as the interior vapor control layer in cold climates. Latex paint is also a possibility, but because it's always vapor permeable (i.e. not hygroscopic - its permeability doesn't adjust to the indoor relative humidity), you have to make sure you've got a good air barrier and can limit air movement into the wall at penetrations, etc. So, what's the basis of your opinion?

I'm going to throw in my two cents on the vapor barrier issue. Depending on the climate zone, local codes may require an interior vapor barrier - the old standby was sheet polyethylene, which is still used and is a true vapor barrier (0.1 perm or less). Nowadays it's preferable to use a vapor semi-impermeable vapor retarder (1.0 perm or less, and greater than 0.1 perm) instead of a vapor barrier. As Alan mentioned, the Pro Clima Intello Plus, imported by 475, is a good product, but it can be difficult to source in some parts of the country. I recommend the Certainteed Membrain, which is also an "intelligent" vapor retarder. Tyvek, and similar "housewraps", are generally vapor permeable (10 perms or greater), and are intended to act as an air and weather barrier, not as a vapor retarder (or vapor barrier).

The polylines need to be closed. First, clean things up a bit - the left brace has some extra lines - then select all the lines and make certain they all have identical properties (Line Style tab). In this screenshot, you can see that the lines don't have the same Weight: After you've made the lines identical, then they will "close" properly, and you will get the option to convert them to a polyline solid.

Can you please post a screenshot showing the condition? Posting the plan also works.

I suggest adding the thickness of the furring strips to the thickness of the siding - IOW, use a single wall layer to account for both materials. This is my strategy for rain screens and air spaces. However, this method won't provide an accurate Section or an accurate Material List. FWIW, I don't include the CI as a separate wall layer either - everything to the exterior of the sheathing I roll into a single layer, then I use details, sections, text, and the exterior elevations to communicate the wall construction. But this is a personal choice - everyone has different needs and preferences.

When a PDF is created, filled areas are broken into multiple triangles. Some PDF viewers have difficulty displaying these triangles properly, and the result is the imperfect smoothing (anti-aliasing) at the boundaries. The printed output should be correct - it's just the on-screen display that is wonky. These articfacts can be better or worse depending on: 1) The complexity of the filled area's geometry. 2) The DPI of the exported PDF. 3) The PDF printer. 4) The PDF viewer. Check your PDF viewer's options, and turn off anti-aliasing; this may provide a more acceptable on-screen result.

Gene, I've specified those frequently for ledger connections but have never considered using them for interior framed walls - it's an interesting solution. Simpson doesn't publish a lateral load capacity in the 'F2' direction, otherwise, these could be used to brace interior framed shear walls instead of cutting back the form. Thanks for the tip.

It doesn't have to. The only scenario I can think of where it would be absolutely necessary is if the interior framed wall was being used for lateral load transfer, in which case you would probably want to be in line with the concrete core of the ICF. Because the embedded webbing in an ICF generally runs vertically, it's common for an interior framed wall to not align with the webbing (which you can screw the end stud to). And, depending on the manufacturer of the ICF, some corner units have a vertical web just on either side of the corner, so problem solved. The framer can always brace the wall to the floor or roof/ceiling.

I'm not sure this is the best solution: Existing_2.plan There are little slices of roof plane I can't eliminate:

Select the roof plane on the first floor and move it up to the second floor, then select the relevant edge and drag it against the 2x6 exterior wall that is aligned with the wall below. You can then move the roof plane back down if you want.

Study the attached plan to get you started. You can accomplish most of this by setting the Roof properties within the Wall Specification dialog box for each wall. ShedGableShed.plan

Don't forget you'll need to shed water from this area:

The near wall can be selected and dragged up out of the way. I'm not sure if there's a more automatic solution for that wall - someone smarter than me may be able to figure it out.

For the far wall, you need to align the wall below with the wall above; then drag the roof edge against the upper wall, then your setting should work:

You can turn this behavior on/off in Preferences:

That cursor indicates that you have angle snaps turned off. Turn angle snaps on, and the icon will disappear.

That is a really interesting capability, that initially seems filled with so much promise, only to fall short in so many ways. Sometimes I feel Chief doesn't follow through on their ideas and implementations. Nonetheless, thanks for pointing this out - I was completely unaware of this feature.

You can combine plan files in Chief, but they won't "auto-update" like an AutoCAD Xref, because they are now part of the plan into which they've been inserted. I've been using TwinMotion, which may do what you want, sort of. You can export your Chief models as .dae files, then import them into TwinMotion - they can be "refreshed" within TwinMotion easily after you've made changes. There are quirks, of course, but TwinMotion is fairly easy to learn and is very fast and responsive. It does crash too often, which I think has something to do with Chief's .dae exports. This screen shot shows two Chief .dae exports, imported into TwinMotion; notice in the Import tab that they are two separate DAE files:

I don't know what controls which Floor Level a Polyline Solid is placed on, but moving it is easy: find it, select it, cut it, move to the desired Floor Level, and Paste>Hold Position.

I can't share the file - I'm on X12, and you won't be able to open an X12 file on X11. Refer to the Reference Manual, I think it can get you headed in the right direction:

For more help, download the Reference Manual for your version of Chief - there is a lot of good info that will help you with manipulating roofs.

Turn off Auto Rebuild Roofs and edit the roof planes manually:
