Slabs are easy. With the polygon editing palette, irregular slabs are easy. For complex section geometry such as a corrugated sheet, you need an object. But such an object is usually rectangular. There is no polygon editing for object elements. It is difficult to code even pseudo-polygon editing into an object, and still the palette wouldn't be available. More

In our true masonry fireplaces, the hearth support is usually a cantilevered concrete slab. The hearth itself is a separate slab with its top at the level of the finish floor, usually 3/4" above story zero. This finish slab may vary in thickness, and will often be thicker than the typical finish floor. You want to see this slab in
Location: 13 Special Construction Two objects (primarily) for cutting coved recesses into ceilings, using solid element operations. One's a circle, one's a rectangle. Guess which is which. The parameters of each are similar. The fillet radius must be less than or equal to the height. The resolution of the fillet is controlled by the Fillet Facets parameter. For the disc,
Location: 13 Special Construction A big dull block for subtracting a rectangular hole into a ceiling slab. Why not use a slab for an operator? Why not just draw a conventional hole in the slab? Because while the 3D block is dull, the plan symbol is rather clever, responding intelligently to the new ceiling switch in Model View Options. To
Somebody asked why the flue object can't show a thickness for the flue liner itself. One reason: The flue sits atop, and lines up with, the top of the smoke chamber object. In section this gives a continuous void. If a thickness is built in to the flue, there would be a discontinuity at the top of the smoke chamber,
Not for Construction The path of the smoke inside the chimney is created by a series of SEO subtractions using the Smoke Chamber and Flue objects as operators. The targets are whatever elements the objects pass though. Each firebox has a smoke chamber directly on top of it. Directly on top of that is a flue object. In a
As you know, you don't cut the grade mesh using the building elements. You place slabs in the shape of the holes you need to fit the building. You might find cases where it's more appropriate to use a roof: Create the roof with the pivot line at one edge. Go to a section and fix the slope graphically, using
Location: 04 Masonry / Chimney & Fireplace It's very hard to describe this object independent of the whole chimney process, but I'm going to try. Once this guy is written up we can look at how it, the firebox, and the flue work together. This version is superior to the JM9 version in that the flue is better oriented with
Attic dormers have long been a black art in AC modeling. The 3D cleanup improvements in AC10 make their behavior much more predictable. In order to see these improvements, make sure this box is checked in Preferences -> Construction Elements: I can't say I've observed a performance hit in using this. No matter, it needs to be on.
Location: 13 Special Construction A rectangular or arched shape for subtracting niches into walls. If the Arch Height is zero, the top is flat. The Wall Pen draws a heavy line around the back of the niche, to match the weight of the wall's contour. The side with the center node should go along the edge of the wall.
As long as I can remember, we've used a polygon wall for a fireplace, with a 3D-only wall or slab above to take the chimney to the ceiling. This method has been developed pretty far. This new method isn't going to give you the 1" chimney section for CDs, but for schematics, it feels a little simpler.
Location: 13 Special Construction For cutting a limited chamfer in a corner of something. Or unlimited, but you could do that with a slab. Use it with Solid Elements subtract. By default, it's vertical, but you can use any Slope between 0º and 90º. If the object isn't vertical, you can also set a Rotation angle. (If it's vertical,
In the ArchiCAD library, there are niche objects, such as W Niche and W Niche Round. These are actually windows. They are built on the WALLNICHE GDL statement. The trouble with these niches is that with the Doors & Windows display option set to Hide on Plan or Reflected Ceiling, they appear to be full, through-wall openings. In addition, they
This layer is for operator elements which you would like to show in plan. Example: You can use the filleted disc and box objects to cut a ceiling, and display those cutting elements in the plan with a dashed line. You still have to draw them over in the RCP, but two elements is better than three. Another example: A
Update. The AC11 versions have RCP-awareness. Location: 13 Special Construction Two objects (primarily) for cutting coved recesses into ceilings, using solid element operations. One's a circle, one's a rectangle. Guess which is which. The parameters of each are similar. The fillet radius must be less than or equal to the height. The resolution of the fillet is controlled by the
Location: 06 Wood & Plastic/Trim & Moulding Identical to Trim Panel JM9, except it's an object instead of a window, and it lays flat. It's for putting panels in slabs, for ceilings. No, it can't actually cut the hole. You have to do that, using SEOs. Target: slab, operator: panel object. Subtract with downwards extrusion. (There is evidence of a
I was happily (!?!) putting in the rake mouldings for the gambrels on Vassos. On the sixth one, the outer rake failed to subtract from the steep roof of the gambrel. All the others had worked. Imagine my joy when I saw that all five previous subtractions at the same condition had also failed. The "solution" is to slightly change
Now that you have a fireplace, you'll likely need a chimney.
Start with a polygon wall in the shape of the firebox and chimney plan. The height should be the height of the firebox opening. The fill should be rubble, assuming stone veneer. 1 Stone polygon wall
Location: 04 Masonry / Chimney & Fireplace A round or rectangular tube for modeling chimney flues. The top can be offset for a sloping flue. Plan Display & Editing "Show Cut" means a white box with a X. "Show Slant" means the path of the sloping flue, typically shown dashed. Both can turned off, in which case the object will
