Week #10 – Using ArchiCAD’s Structure: Guiding Principles
10-3. Anchor Your Design Intent

ArchiCAD Training (Best Practices Lesson 10-3)

This 31 minute lesson demonstrates how proper referencing and anchoring of elements will help ArchiCAD maintain your design intent.

This tutorial is closely linked to the previous one that discussed the use of simplified “placeholder” elements that may be replaced later with detailed components. As the design process unfolds, some parts of what you draw or model are more important than others. For example, early on, you may not have decided the exact wall assembly you will use, but you may already care about certain critical dimensions. By placing the wall reference line in the most appropriate way (for example, to the outside surface, inside surface, or outside face of framing), the distances entered while drawing the walls are linked to what is important to you. Later, when you make a decision (or experiment) and set the wall assembly to a specific type or a different version, these essential dimensions are maintained.

Before placing walls, it is best to choose the most appropriate construction method (left, right, or axial) and an optional offset for the reference line. However, ArchiCAD is quite forgiving and flexible. When you change the wall(s), one can use the Design menu > Modify Wall > Structure or Modify Wall > Reference Line commands to reconfigure one or more walls in an intelligent manner.

While placing windows and doors, the insertion method (center or corner) is recorded and becomes part of the element definition. This placement anchor is maintained when the size is changed, so the window will remain centered in the room between two adjoining walls, or a door may stay the proper distance away from the wall intersection.

Anchoring choices are useful for columns and beams in a similar manner. If they change size or style, their corner, edge or centerline may remain fixed in relation to other elements.

Text and labels also have anchors, and these may be used to simplify placement and manipulation.

    So, it appears that in v.19 under “Design”, that the “Modify Wall” tool doesn’t exist…any idea what they might have changed it to, or relocated it to?

      Hi Julia –
      You’ll find similar functionality available in the Edit menu > Reference Line and Plane > Modify Wall Reference Line [and Invert Wall Direction, under the same submenu]. ArchiCAD has gotten smarter about reference planes; now you can set the elevation of a slab based on the base, the top, the base of the core or the top of the core; before the slab tool elevation only referred to the top of slab level. So they generalized the controls, and moved them into the Edit menu since they now relate to more elements and will be more frequently accessed.

      Benjamin –
      The video appears as usual on this page. Sometimes the video server responds slowly, so the video player doesn’t appear on the page for a while. You can try refreshing the page, and waiting for a full minute, or coming back later, after watching other videos.

    You’re right in that the Design > Modify Wall > Structure command was one that I was not familiar with! That is a great tool to be aware of.
