(1) A custom profile for modeling and (2) an object for annotation.
Profile:
In the profile editor
• The horizontal stretch extents are inside the fascia board reveals. This way, when you adjust the overall width the fascia thickness will be unchanged. Similarly, the vertical stretch extents go from the top to the underside of the soffit, leaving out the reveal.
The custom profile tech only allows you to stretch one dimension horizontally and one vertically. You can exempt parts of the profile from stretching, but you can't stretch them independently. If you want a different reveal depth or fascia thickness, you'll need another profile.
• Profiles can stretched bigger, but not smaller. (I call this a bug, but what do I know.) Any profile you intend to use with varying dimensions needs to match or be *smaller* than the smallest case you have.
• The templates have two profiles, Coffer Beam and Coffer Beam Half. Both are 4" x 2" which should be small enough. The half version has the fascia on only one side and is meant to be placed along a wall.
Remember that profiles are attributes, so they're within the project file, so you can edit them without messing up anybody else. And: You can use Attribute Manager to bring profiles into the current project from the templates.
Here is a sample condition at 1/4" scale, no detail added:
At higher scale, we need to add detail:
Object: Soffit Beam Section JM10
Location: 06 Wood & Plastic / 2D Wood
The object fits within the profile's perimeter.
• Height and width of the object will match that of the beam itself.
• Parameters for Fascia thickness and reveal.
• Crown Hgt sets the point at which the pen switches from the object's cut pen to the Separator Pen. In practice this height should meet the bottom of a crown object placed against the beam, which will maintain the heavy outline.
• The Half option uses one fascia board to work with the half version of the profile.
Commentary:
We build one model. We take views of the model and annotate them as needed. We will take views of the model at various scales. Scale is fundamental to architectural documentation: As we look closer, we see more.
Yet Archicad lacks any meaningful automatic scale sensitivity, except that written into objects by people who want it such as me.
In this example, see how the crown objects draw themselves as empty blobby things at 1/4" scale, but they're detailed shapes with proper fills at higher scales. The roof, slab, and beam elements, not so much. (Archicad library objects, not so much either.)
Since we can't get conventional AC elements to detail themselves according to scale (yet, I hope I hope), we need to build a model that can accommodate the detail we need to add. This is the idea behind something like the Stud Wall Detail object. The wall is empty, and we place the object in the viewpoints that need it.
The soffit detail described here has always been tricky. If you approximate the beam with a rectangular model, it's difficult to manage the reveal without masking. It's easier to add 2D detail than to subtract modeling.
A custom profile allows us to handle the cased beam in the "Empty Fill +" fashion we are accustomed to with walls, roofs, and floor decks.
