This 35 minute lesson explores a variety of methods, settings and approaches to modeling to create clean, detailed elevations and sections.
When elements such as walls and slabs are stacked properly, ArchiCAD will not draw a line showing where one ends and the next one begins. The main requirements to get this result are:
This works for “generic” elements such as walls, slabs, columns, beams and roofs. Note that many objects will draw their own edge lines regardless of positioning. However, some objects are “smart” enough to have a parameter or option to make certain edge lines disappear. A typical example is a cabinet which may show or hide the edge of the countertop to allow multiple cabinets appear to have a common top surface.
When the View menu > Onscreen View Options > True Line Weight is turned off so all lines are drawn as a hairline, it is easier to see the precise alignment of elements. However, to get the nicest looking drawings, from time to time it is important to inspect and adjust your drawing with true line weight turned on. One may need to change the settings of certain parts of elements; for example, in this lesson, the window sills were originally drawn with a heavy line, and were revised to make them thinner.
3D Vectorial Hatching is an option in the Elevation Settings > Model View that (when turned on) shows tiles, shingles or stonework etc. based on the surface materials. One may adjust which pen and therefore what thickness or weight these lines will be drawn with using settings in the Options menu > Element Attributes > Material > Vectorial Hatching dialog.
Modeling 3D elements in a more sophisticated manner can add more detail to the elevations and sections. Often this is done with complex profiles to show different materials and geometry (e.g. the walls with a stone base and stucco at the top; also the cornice under the balcony). In the Start Edition, since it does not allow complex profiles, one can create custom objects with a complex shape to partially work around this limitation.
Solid Element Operations (SEO) are often used to add more geometric detail or clean up connections or relationships between elements. For example, the ornate rafter tails are modeled using a simple object (as created by the Roof Framing wizard), then cut using an SEO subtraction to create the sculptural end. Similarly, the stem wall and footing is modeled with a complex profile, then this is subtracted out of the terrain mesh using an SEO.
In a section, framing may be shown using 3D elements or with 2D objects (built-in to the library or created as Patches) or simple linework. Both 3D and 2D methods may be used in the same drawing, based on your preference and level of skill. 3D approaches to framing generally are a bit more complex, but often save time when done right.
The lesson closes with an examination of some extremely detailed complex wall profiles that are provided as working examples in MasterTemplate. These walls are built with framing as well as extra details such as waterproofing. They require only a bare minimum of 2D drawing to create good-looking longitudinal sections or enlarged wall sections.
