To Mod or not to Mod

We often use modules to place buildings onto a site. This gives us a lot of flexibility and freedom to position and locate the building(s) within the terrain, without the need to use excessive grouping or difficult selections. It also allows buildings to be documented orthogonal to each other, regardless of final positioning on the site.

If, however, a single building or orthogonal cluster of buildings is the final design, it is almost always easier to avoid modules, and simply reposition the site around the buildings to make adjustments.

Here is a chart to help determine wether modules should or shouldn’t be used to place buildings onto the terrain. In the case of this chart, we can assume “Maybe” is understood as “probably not”. The important thing to note is , if the project entails a single building on a fixed position (infill lot), modules are never used, and if a project is to be a multi-building design of non-orthogonal or non-interconnected buildings, modules should always be used.

Isolating Elements

Working efficiently in ARCHICAD boils down to isolating out only the portions of the model you need to view. Viewing the entire model at all times is inefficient and ineffective, since plans can look to cluttered, 3d can be too slow, and section and elevation views may show more content than is relevant to the work that needs to be done.

Isolating elements out is done by the following methods (and different methods may be more useful in certain views than others):

  1. By Selection
  2. By Marquee
  3. By Layers
  4. By Renovation Status (not shown in video below)
  5. By Filter and Cut in 3d Palette
  6. By Cutting Planes

The following video quickly covers most of these methods of isolating elements in plan and 3d.

Attribute Clean Up/Backup

If you are working on an attribute clean up, either a delete & replace or an attribute manager purge (see attribute management on the BIM manual for which attributes should be managed this way), make sure to back up your attributes first.

Attributes should be backed up by ID, not by name, so that if they do need to be brought back in to fix missing attribute problems, they are reassigned automatically.

To back up your attributes, open the attribute manager under options > element attributes > attribute manager. Select the all tab (upper right), reserve all under the teamwork drop down (bottom left), the select By Index >>. Next select Save As… and save the attributes to a folder in your projects BIM folder on the file server.

When you need to bring an attribute back in, select open in the attribute manager. Opening this AAT file will bring in all attributes. Go to the attribute type you need to restore, find the attribute, select and click << By Index. Note that this will replace an attribute that may have been created or modified to use that original index number, which will change all instances of that attribute’s occurrence in the model.

Also, note that whenever doing an attribute clean up, reserve all first to ensure any replaced attributes are actually replaced in the model elements that use them. Any unreserved elements who’s attributes have been replaced will show as missing attributes.
