ARCHICAD Training Lesson Outline

Detailed Modeling Using Complex Profiles and Building Materials

Finishing up a couple of things from last time that were missed:

  • Vectorial hatching on Elevations - adjust the pen and therefore the thickness or weight for these lines using the Options menu > Surfaces > Vectorial Hatching dialog.
  • Solid Element Operations can be used to subtract out a foundation from the terrain, possibly combined with Complex Profiles. Examples: stem wall and footing modeled with a complex profile, subtracted out of the terrain mesh using an SEO; excavation under the building using a slab set as a hidden SEO operator (placed on a layer normally hidden), subtracted from the terrain mesh.

Complex profile walls can include framing and waterproofing that may require a bare minimum of 2D drawing to create good-looking longitudinal sections or enlarged wall sections.

MasterTemplate working examples are found in the Interactive Legends as well as in the Sample Project.

Tim Ball has shared some intricate examples (see screenshot, left) - he is a master at modeling in great detail.

Proper setup and use of Building Materials is an essential framework for generating clean, accurate, detailed Section drawings. Best Practices methods for modeling since ARCHICAD 17 use elements that intersect with each other, relying on ARCHICAD to calculate the appropriate section view based on the relative priorities of the building materials.

A convenient and powerful method for testing and optimizing Building Material priorities is to select the elements involved in the intersection, then open up the Options menu > Building Materials dialog. The Building Materials included or used in those elements will be highlighted in green, allowing easy study of the priorities to understand what is going on. Sort by Priority by clicking on that header, then one can see the list in priority order. Drag and drop a Building Material into a new position to quickly change the priority; one can also type in a value.

Key principles for intersection calculation:

  • Building Material Priority numbers determine which pass through and which stop or disappear from the intersected area
  • Elements must be on layers with the same layer intersection group (if on different groups, intersections are not calculated)
  • Walls, slabs and beams naturally will participate in intersections
  • Complex Profile Offset Modifiers (introduced into ARCHICAD 22) in many cases allow easier and more sophisticated manipulation of wall cladding than basic Building Material intersections

Coming Up Next Time Around

In the next lesson we'll continue our study of detailed modeling principles, and explore these areas:

  • Roofs must be Connected or Merged to intersect
  • Solid Element Operations may be used to define the geometry, however they take effect AFTER the Building Material intersections are calculated

Horizontal framing can be placed using beams or as part of wall profiles, however extremely careful setup is required to show properly in all contexts (section drawings, marquee cutaways, exposed ends).
