At Rill Architects we run ArchiCAD on Mac OS X. If you work at Rill, this is your stuff. If you don't, but you work in ArchiCAD, you may find something interesting. Anybody else, I don't know.

With the advent of graphic overrides, reflected ceiling plans are no longer a wilderness of tracing and weird hacks. What shows: • Walls • Ceiling trim and finishes • Ceiling fixtures including lights, fans, and mechanical fixtures • Floor elements, including deck edges, stairs, counters Using graphic override rules, floor elements are automatically shown dashed in RCP. And, ceiling
Graphic overrides greatly expand the number of ways an element can represent itself in different kinds of documentation. This means less redundant 'drawing', and more unity. The RCP has long been a frustrating form of output if you're trying to minimize drawing. All the things that need to be shown are modeled, but Archicad has had limited facility to present
Several different kinds of change, which may overlap. New versions mean new workflows, and that means layer changes.
This is a new approach to showing openings in reflected ceiling plans, using a modified plan symbol rather than an blank opening. I haven't put it in the template yet, and it may not be required or appropriate for every project, but it is better overall. The biggest limitation is that in order to use it you have to use
I added an option for an elliptical curve. Original and download link here.
Location: 06 Wood & Plastic A sloped series of boards to support a flying rafter. This thing is hard to show in place; here's a section through the eave of a dormer, showing the dormer wall in elevation: The Roof Slope can be selected from a familiar list of n/12 slopes, or you can use a custom angle. You can
Location: 01 General / Drawing Tools System requirements: Accessories add-on in Add-ons folder An accessory as a special object that can be associated with another element. When you edit the element, the accessories edit themselves to keep up. This kind of automatic geometry is rare in Archicad, and welcome. Yet the accessories live in the limbo of semi-features known as
AC11 has a model view option to put the floor plan into reflected ceiling mode. It only works for objects, not regular elements (wish wish wish). I have several objects that take advantage of it. This is the basic code you need to have a symbol draw itself differently in floor plan and RCP mode. The idea is that depending
The reflected ceiling plan is a universal drawing type that Archicad simply does not handle very well. We took a medium-size step forward in Archicad 11 with addition of the 'Ceiling Plan' model view option for GDL objects. This allows object developers to make objects that draw themselves differently whether the 'Ceiling Plan' or 'Floor Plan' setting is active.
Location: 06 Wood & Plastic A beam, or any other ceiling element, should be shown dashed in the architectural plan, because it's overhead. That same beam needs to be shown solid in the reflected ceiling plan, because then you're upside down looking straight at it. Using a conventional beam element, you would draw it with a dashed line in plan.
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
Location: 13 Special Construction For modeling a vaulted ceiling under a flat ceiling or a gable roof. Heights are editable in 3D and section. Turn on the Ellipse parameter for an elliptical curve. Other wise it's a simple arc. With the Model View Options in 'ceiling mode', the object can use the optional ceiling pen, linetype, and cover fill. (Use
In Model View Options Location: 01 General / 2 Drawing Tools Among the least heralded new features of Archicad 11, tucked into the bottom of the Model View Options dialog, is the modestly named 'Story Viewpoint Type'. Not heralded at all, in fact; there's no mention of it in the New Features Guide. I understand why they don't want
Location: 06 Wood & Plastic/Trim & Moulding New version of the main moulding object. Listen, you will have dozens or hundreds of Crown Tool elements in a project. The object is designed to be used all the time. I.e., it does a lot. Get familiar with what it can do. If it doesn't do something you need, speak up! This
Location: 01 General / 3 Drawing Tools To help locate overhead ceiling lines. This is a little weird but you'll get it.
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
A single building element, how about a window, will be represented multiple times in the construction documents. There's the window in a plan, at least one elevation, often two or more sections, maybe/probably an interior elevation, maybe a wall section, and the window schedule. Then there are dimensions and annotations related to the window. Five to fifteen representations of one
NOTE: This info has been substantially updated. RCPs are largely, not entirely, drawn. This is a gross deficiency of Archicad in it's current form. GS has to fix it, we can't. (It wouldn't be hard, though.)
Here's a new trim layer. It shows in the same layer combinations as the other 'F Trim'. In addition, it shows in the reflected ceiling plan, which is the point. Place Crown Tool objects on this layer and you can avoid redrawing the crown for the RCP. The layer has been added to the templates. Add it to current projects
