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.

I didn't want to talk this to death. What I like about alignment charts is they are assertive rather than argumentative. You have to just look at them and work out the relationships among the things, and ask yourself if your impressions of the things agree with the author's. I made this by instinct. The strongest notion I had
Graphic overrides are a new feature of Archicad 20. They allow you to choose elements by criteria, and change their appearance attributes. The changes are grouped into combinations which can be saved with views. Here's how to use Archicad: Build a model, and try to create all the documentation while doing the least amount of non-modeling. If you find yourself
The user has requirements. The software has capabilities. Where the capabilities end and the requirements keep going is a limit. To get beyond the limit requires workarounds. Some limits are harder than others and all we can do is wish (beg) them removed. Here's a rich example concerning structural posts (columns) in residential construction. These are things like 4x4s, multiple
Here I present an extra-strident version of the usual consistency argument. Graphisoft should adopt as an unbreakable regulation the idea of a Standard Element. All elements would be required to meet the standard, otherwise they're not elements. Graphisoft would mostly be enforcing this law on themselves, though add-on developers would be bound by it as well. In turn, Graphisoft would
Kinda looks like a jellyfish This image shows a few isolated elements from a lighthouse-looking tower structure. The 54 columns are balusters for the stair railing. The 110 objects are wood beams for the roof framing. By themselves, it's not a lot of elements, or even a lot of polygons. Yet these guys were found to be the cause
Something to think about, or maybe not. Not all objects have to be right in every way. Plan symbol Plan symbol on remote stories 3D hidden line 3D shaded 3D render Elevation Elevation in distant area Section Polygon efficiency Scale sensitivity; which compounds the plan symbol, section, and polygon issues Listing Labeling User interface Parameter list Parameter transfer management (Unique
I inherited a project where an important dimension was supposed to be 12'-9" and instead it was established as 12'-9 9/64". The fraction rounds to 1/8", which resolves in the dimensions (12'-9 1/8"), so I have to fix it or customize the dim text, which would violate various Prime Directives. And it's my fault I didn't catch it before adding
Location: 06 Wood & Plastic / Railings & Stairs (I'm thinking about moving it, since it's not really a fine detail-type thing any more. More like a missing tool thing. Not to mention, it could be concrete. I really wish the object browser could handle aliases. As for now, there it lies.) UPDATE: Stair Body JM9a is exactly like Stair
Accuracy is first. Completeness is second. We're talking about construction documents of course. The end product of our work is a building. The documents are the primary device for ensuring the building is executed in accordance with our design intent. Therefore, in evaluating the quality of documents, we are really talking about their reliability. Using these documents, how close to
There are six. Impossible: Literally. Not a slang term for "very hard". Some people will say that nothing is impossible. This is obviously not true. Somebody: Nothing is impossible! Me: Can you walk to the moon? Somebody: Of course not! Hard: Possible with effort, time, concentration, creativity, energy. Example: Flying to the moon. Tedious: Requiring time and energy, but not
Starting with AC 10, we will use 'real' section markers. When we started with AC 5.1, there were fixed section marker styles. (Like the fixed dimension ticks and arrowheads to this day.) We didn't like the available styles, so we adopted the policy of showing sections in plan with an object, independent of the SE cutting element. The independent object
Build it like they build it except when you can’t. Stay organized. Be consistent. Don’t draw anything you can model. Do everything as needed. Meet the demands of the current situation. If you can’t see it, put it off. Throw down an element, then fix it. Fix the mistake when you see it. Fix the whole mistake. Find & Select.
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
These are the primary functions of layering, in order of importance: 1. Control of display for output. The finished output has to show and hide the right elements. 2. Control of display for working on the project. Showing and hiding elements depending on the work you are doing at the moment. 3. Promotion of logical thinking about the project as
There's lots of good reasons to invest the time needed to work the model out. It helps you understand the design, find massing problems, catch tricky details, and get lots of drawings started at once. Lately we've noticed an advantage that is distinct from these, but related. With a well-developed model, we are less vulnerable to construction errors arising from
In the future, buildings will be engineered and documented exclusively using virtual modeling techniques. The near future. The term 'model' is being used in two ways: To pretend to build, as with clay or Legos. To simulate using math, logic, and rules, as with climate modeling. Carry this further, and we see that the virtual building model contains two types
