Schedule Criteria

We have looked at why doors and windows may not appear in an ARCHICAD schedule, or why they may not appear in their related zone before. Here is the link to that post, which is worth re-reading as a refresher.

The past couple weeks I have been getting more scheduling questions; more related to eliminating certain elements from a schedule, or why unexpected elements are showing up in a schedule. The answer is almost always due to an error in the Schedule Criteria Settings. Here we will look at a few scenarios that may cause undesired results with your schedules, all linked to incorrect criteria.

Fig. 1.0 Incorrect use of “and”Statements

In Figure 1.0 above, the Element ID that can be listed is using an and statement, rather than or. The result is, no elements will schedule, since it is impossible for any elements to meet the criteria of start with 0 and 1 and 2 and 3. We often list multiple element ID in our schedule as a first digit as an easy way to seperate schedules out by building or by floor for multiple building projects. To fix this, the Element ID Criteria should be bracketed, and each ID starts with line should end in or.

Fig. 1.1 Unbracketed “or” Statements

In Figure 1.1, the ID starts with lines are correctly ending with an or statement to continue to the next criteria line; but they are not bracketed. The result will be windows that start with 0, or ANY ELEMENT that starts with 1, 2 or 3 will show in the schedule. To correct this issue, simply add a bracket before and after the or statements.

Fig. 1.2 Incomplete Bracketing of “or” Statements

The last example, Figure 1.2, shows a partially bracketed “or” section of the Criteria. By not closing the bracket, you will see a warning in the Scheme Settings noting that the Criteria is Invalid! The result will be nothing can schedule until the brackets have been correctly applied.

Hopefully this gives a little more insight into what may be going on with your schedules, and why things are missing, or too many elements are being included.
