    Measuring Height of Interior Attic Space?

    I want to mark the areas in my attic which have 7+ feet of clearance from the top of the joists to the bottom of the rafters. I can think of some ways to do this including manually measuring in elevation views, but that would be slow. Another idea: I could use a custom countertop set at a height of 7 feet above the joists then adjust the edges in 3D until they just touch the roof rafters (then trace it with a normal polyline). Can anyone think of a better way?

    Measuring Height of Interior Attic Space?

    Actually, the countertop polyline is working really well so far. I just made an orthographic full overview and am viewing the roof top down and dragging the counter edge until I can just barely see it. I have it set at 8 feet above the attic "floor" (which is the top of the finished ceiling) to account for joist and rafter thickness. This is good enough since it doesn't have to be exact.

    Change in Roof Pitch Along a Single Wall

    I'd like to do a hip roof with pitch changes along a single exterior wall. Can this be done without manual roof edits (using wall directives, or roof baseline polylines, or some other technique I don't know of)? I've attached an example image of what it should look like. The ceilings are the same (9') throughout. The low roof is 9 over 12 and the higher part has a 9 over 12 skirt around the edges to match, then changes to 16 over 12 starting 0.5" from the baseline. As you can see, the 16 over 12 section has 4 main roof planes (plus the skirt) but the 9 over 12 section intersects the higher section and has only 3 planes. I've tried making this in 4 different ways and the last two ways almost work. 1) If you try to simply split the long exterior walls in half and give different pitch directives, the auto roof chooses one of the two pitches and ignores the other, so this doesn't work. 2) If you make two roof groups using a room divider, you end up with two entirely separate roofs (two points; the lower hip roof isn't joined to the higher roof because it's in a separate group). 3) If you make two roof groups as above and make roof baseline polylines, you can change the interior pitches and cause the lower roof to intersect by overlapping the interior portion of the roof baseline polylines. Set the 9 over 12 section to "against wall" and the high section to 9/12 and 16/12 to match the exterior walls, and manually intersect them by moving the "against wall" baseline into the higher roof. This works except the lower roof extends into the attic of the higher roof which isn't ideal since I'd like to visualize the attic space properly. 4) If you manually create two separate baseline polylines in the same group via copy/paste, you can set the separate roof directives as above, but since they're in the same roof group, if the outer lines are flush, a single pitch is chosen for the wall again (just as in case 1). If you separate the baseline polyline edges by a fraction of an inch along the exterior wall it creates separate planes as intended, but it creates a discontinuity along the eaves that you can see in the 3D view (pictured) and it causes the shingles over the 16/12 hip to extend all the way down whereas they should stop around 0.5" from the baseline.

    Change in Roof Pitch Along a Single Wall

    No, the ceiling height and wall height doesn’t change. The eaves, fascia and soffit are at the same height in the two sections and continue seamlessly where the roof changes. This seems to be the purpose of having the 9/12 “skirt” at the bottom of the 12/12 section. It means all the eaves are formed from 9/12 roofing and can connect seamlessly.

    Change in Roof Pitch Along a Single Wall

    I did and just got the reply. They've said that manual roof planes are "best" in this situation. Apparently there is no work around aside from what I've already done.

    Using Roof Baseline Polylines

    In case anyone is interested, the documentation for RBL (Roof baseline polylines) is much better for chief architect than for home designer pro. Here’s a good instruction page and a training video I found: https://www.chiefarchitect.com/support/article/KB-00543/utilizing-roof-baseline-polylines.html https://www.chiefarchitect.com/videos/watch/706/roof-baseline-polylines.html

    Using Roof Baseline Polylines

    Is there any detailed documentation about roof baseline polylines and how they work? I can't seem to find anything, but have got a lot done just by tinkering. One question I have is, where should the polyline typically stop on exterior walls? When generated automatically, it seems to go to different areas (sometimes to the outside of bricks, sometimes only to the outside of framing, sometimes to the inside of framing). Overlapping doesn't seem to cause any problems, in fact, sometimes it seems essential to solving problems. For example, the green outlined section in my attached image is a hip roof over an area with 12 foot ceiling, while the neighboring areas have 10 foot ceilings. Getting the southern edge of the hip plane to form a proper valley was impossible without overlapping the polyline on that side. I've taken to creating multiple independent and overlapping baseline polylines to get the roof I want. It's been especially useful in sections where there are two different pitches projecting from a single long wall (the automatic system seems completely unwilling to do that; it always just ignores one of the mismatched pitches along the wall). It seems like you ought to be able to simply draw a new roof baseline polyline, but I haven't found any way to do that. Instead, I just create a simple rectangular temp structure and then copy and paste it's baseline polyline as needed. At least that automatically sets the baseline height (it generates at 9 and 9/16 inches above the absolute ceiling elevation if you need to set it manually).

    Multiple Gable slopes - no wall framing?

    You may want to attach the plan file to a post. Someone will load it up and fix it or offer suggestions.

    Using Roof Baseline Polylines

    I can upload a plan either late tonight or tomorrow morning. You don’t really need elevations through. Rooflines should all be at the height required by 10 foot walls/ceilings, except the front “stoop” which has a 12’ ceiling and roofline to match, and the section between garage and stoop which is at 11 feet. Roof pitches are all 9/12 except (assume the top of the plan is north) east and west facing planes are 12/12 over the garage, over the front stoop and over the main body of the house (so back porch is all 9/12; and the section connecting garage to house is 9/12). Also, the 12/12 sections I just mentioned all begin with a 9/12 pitch for about 18 inches before switching to 12/12. The top down view of the roof I posted is accurate except doesn’t include the 9/12 at the bottom of the 12/12 sections. I’ve since added that using the upper pitch feature. Really though, just make a a long rectangular “house” with two different roof pitches along the same wall if you can. That’s the main thing I’d like to see if it can be done.

    Figuring out object placement...

    I guess what’s odd is that they set the bounding box to 30” wide by default. But some people will want more space and codes could even change. I wish the toilet object was simply it’s actual width and there was another method for establishing clearance.
  12. davidstvz

    Figuring out object placement...

    Oddly, the width and depth of toilet objects includes some space around the toilet. For simplicity, I just set mine to 3’ wide to represent the width of the space I want for my toilet. You could use the tape measure to measure the actual toilet and shrink the size an inch or so at a time until it actually matches a real toilet. Then you just need to be careful to make sure the space it sits in is the size you want.

    Using Roof Baseline Polylines

    The ceiling heights are the same in that area. I suppose if I played with room heights I might convince the system to generate that roof, but would that really be the best/right way to do it when the exterior walls are supposed to be at the same height? I think baseline polylines are far more appropriate here since changes to them only effect the roof.

    change exterior material later in the process

    Defaults set what new objects are created with. To change existing objects you need to use the material painter tool. While in a 3D view, go to the menu "3D -> Material Painter" and observe the tools there. You have the painter (with several modes/options) and the eyedropper. If you choose the painter, the library window pops up and you use it to select a new material. You can also use the eyedropper to select an existing material from the 3D view. Once selected, click a surface in the 3D view to replace it's material with the one chosen. Depending on the mode of operation, other materials in the plan may or may not be replaced. It sounds like you want to use "plan mode" which replaces every identical surface with the new material using a single click. This won't concern you at the moment because you're applying materials with textures, but note that color materials (i.e. paint) have no texture associated. If you're painting colors without texture, the tool by default will not remove the texture already applied to the surface. For example, you apply color to brick and you get different color brick, not a flat non-brick surface using your color. To apply a flat color to a textured surface, removing the texture, deactivate the "blend colors with materials" option.

    Odd sizes in Material List

    What you want to do is a feature of Chief Architect Premier: https://www.chiefarchitect.com/support/article/KB-00095/creating-a-cut-list-of-framing-materials.html Honestly, if you just buy one normal 8' or 9' stud for each short stud and cut them, you'll be pretty close to what you want anyway. How much of those wasted 3 3/8" pieces do you think you can use? If you learn a little Excel, you can easily use the cut list to generate a custom buy list.

    Using Roof Baseline Polylines

    I agree, it is a straightforward hip roof designed by a professional architect which I am not. However, I don't see any way to auto-generate it from wall directives. In particular, how do you create two different pitches along the same wall (as in the east and west walls of this structure)? I personally find the baseline polylines to be a very intuitive system with more ease and power than wall directives while being not nearly as complex as manual roof editing. If you've mastered manual roof editing, I can see why you would disregard it, but there are a lot of amateurs here who can benefit from it.

    Odd sizes in Material List

    Yes agreed, 7'-8 5/8" and 8'-8 5/8" are very common (especially the 7'-8 5/8"). You combine with a bottom plate and double top plate (4.5" total) for a rough ceiling height of 8'-1 1/8" or 9'-1 1/8". The extra 9/8" accounts for 1/2" drywall and leaves 5/8" for flooring finishes so you can have approximately 8' or 9' between the floor finishes.

    Odd sizes in Material List

    Where is 2x4x10 not a standard board length? You can get 10 foot long 2x4, 2x6, 2x8 or 2x10 right now at the Lowe's down the street from me. Surely a lumber yard would have them. In any case, I don't see any way to modify what lumber is considered commonly available. Your best bet to mimic the functionality would be to generate a cut list, export it for use in Excel and then use some kind of VB script or Excel formulas to generate a buy list from the cut list using your own custom list of lumber sizes.
  19. I agree 100%. The auto dimensions clutter things up far too much, so I always rely on temporary dimensions, or temporarily placed manual dimensions.

    Using Roof Baseline Polylines

    Here's a summary of what the manual says (roughly) about roof baseline polylines: 1) How to create and display them in the first place, and that you'll get at least one baseline polyline per wall height in your exterior wall layout. 2) It tells you that editing (changing the shape of) roof baseline polylines is much like editing any polyline (which is almost true). 3) It mentions that the baseline polyline edges have roof directives just like exterior walls. 4) There's a very simple example where a porch is created which is probably better addressed via other means (such as using railings or room dividers to define the porch so that it has a roof overhead automatically). What it doesn't say: They never really gives you a good reason for why you might use them and very little guidance on how to use them: 1) With regard to editing the baseline polylines, they forget to mention that edges set to "Vert-V" (i.e. against wall) are forcibly aligned at right angles to the grid and their vertices cannot be combined to simplify the polyline. If you need to remove a vertex, you need to set both adjoining edges to hip and then combine the vertices. 2) The automatically generated baseline polylines may be needlessly complex if you have two or more different ceiling heights along the exterior walls. The polyline will follow the shape of the interior rooms which match its height (marking each edge with "Vert-V") whereas the roof system is probably only using directives in the exterior portions of the polylines. The only purpose of the interior portions is to ensure that all portions of the structure are covered, or to set some sections to non-hip on occasion. It may be preferable to create your own much simpler set of baseline polylines and allow the interior portions to overlap for the sake of simplicity. Just don't leave a hole in your set of polylines as that will create a hole in your roof. 3) It doesn't tell you how to manually create a new roof baseline polyline, which makes sense because I don't believe you can do so directly. Fortunately, you can copy and paste existing ones. I recommend making a simple rectangular structure as I said above so you can copy and paste it's roof baseline polyline as a way of creating new ones (if needed). Remember to increase the height if needed. Best reasons to use roof baseline polylines: 1) It would be a good idea to work with wall directives first and learn how those work before using baseline polylines as most of the time you can get done what you need with the wall directives. However, if your auto roof is not behaving as expected, one strategy might be to generate the polylines and then inspect them manually to see where your problems are (and use what you learn to correct the directives in your exterior walls, delete the polylines and go back to a normal auto-roof). 2) Your roof section with a different height is not behaving as expected. I've been able to fix some issues that, so far, I am unable to fix with wall directives, though I'm not prepared to go into detail about this yet because I'm really not sure what the problem is yet or how I fixed it. 3) You cannot have two different pitches emanate from one exterior wall. If you generate the baseline polylines, you can see that it choose one of the two pitches and makes a single polyline edge. Even if you manually create two separate roof baseline polylines with different pitches, if two edges are coplanar and the baseline is set to the same height, the auto-roof will only generate one plane using one of the two pitches. To force two separate pitches, you need to bring one of the two edges inward just a bit (if you don't bring it in too much, the roof edge remains flush thankfully). I will attach an example (the house I'm living in is designed this way). Notice both the left and right exterior wall sections change from 12 over 12 to 9 over 12 pitch seamlessly. Edit: DJP, I'm curious if you can generate the roof in the attached images without using manual edits or baseline polylines. All ceilings are at 10', except the front porch is at 12 feet and the room/wall immediately to it's west is at 11 feet. The house plan actually specifies a 9/12 pitch everywhere, including all around the edges (just for the 18" or so inches it takes to reach the exterior walls) then a change to 12/12 on the following east/west facing planes: the pair over the garage, the large pair over the main body of the house, and the pair over the front porch. All north/south planes are 9/12. It seems the only way to make two different pitches happen on a wall is to split the exterior wall and move part inward 3 whole inches. With baseline polylines, you can create the separate pitches by moving a section inward the slightest fraction of an inch.

    Will Home Designer Pro calculate a roof area sq ft?

    To state this more clearly, if you generate a material list for all floors and find where the roofing shingles are listed, that should give you a good idea of how many roof squares you have. Note that if you apply the roof shingle material to anything besides the roof, it would get counted into this total and make it inaccurate.

    I’ve already read those two pages, twice actually. I agree it’s good to read the manual, but it’s very limited here.

    Using Roof Baseline Polylines

    I agree that one should read the manual and try to understand the tools, but it's not always easy to do. Tinkering has always been my means of learning computer programs. It does occasionally get you into trouble unfortunately. Well, if no one else is up to the task, I will post info about what I think I've learned about roof baseline polylines here.
  24. davidstvz

    Using Roof Baseline Polylines

    Here's something to get you started. Go to the menu and click: 1) Build -> Roof -> Build Roofs 2) Select auto roof and "make roof baseline polylines" NOTE: if you ever want to go back to a normal auto-roof, you have to get rid of the roof baseline polylines you just created. The easiest way to do that is from "Edit -> Delete Objects". Just click "roof baselines polylines" check box and confirm, then build roof again but without the baseline polylines checked (or check it again to regenerate new ones). 3) To actually see the polylines, you need to go to your plan display options and then enable "roof baseline polylines". Finally, I find that the easiest way to see the roof is using a full orthographic overview and then just rotate the camera to be looking straight down (pan the camera by holding the middle mouse button until you're centered over the house and zoom in with the mouse wheel to get the kind of view in my attached image; consider temporarily painting the roof ridges with slate tile as I did to make them easily visible). Now using the "window" menu, split your view to a vertical layout with the plan on one side and the orthographic view on the other. Now you can easily see how changing the polyline changes your roof.

    Exterior Wall Height for Roof?

    Wall heights seem determined by the room structure height, but some exterior walls in my house are higher to accommodate the roof. In particular, I have a bedroom with 10' ceilings (most of the house is 10') but a section outside this bedroom has a 12' wall for the roof (the eaves are at 11.5'). The front stoop has 14' walls (13.5' eaves) but the ceiling is only at 12.5'. What's the proper way to handle this? So far I just increased the room structure to match the outside wall I needed, and then made the ceiling thicker. Seems like there should be a better way.
