Find elements by class, name or property

What you'll do

Pick every element of one kind or with one value in a single step: every door, every wall on Level 2, every element whose fire rating is EI60, every wall that costs more than a set amount.

Steps

1. Open an IFC model.
2. Open Find in the left panel.
3. In the first rule, choose a property (the element's own ones first, such as Class and Storey, then the model's property sets), how to compare, and a value. The value box suggests the values the model has.
4. To narrow it down, click Add a rule. Choose Every rule to need all of them, or Any rule for one of them.
5. Click Find, or press ReturnEnter in a value box. What matches is picked.
6. To keep the rules, click Save as a set, type a name and click it again. Click a set's name later to find with it.

What you should see

• The matches picked in the 3D view and the model tree, and Properties saying how many by class. Press II to show only them, HH to hide them.
• Words match without caring about capitals. Numbers compare as numbers: "is more than 1000" means the value, not the text.
• has a value and has no value need no value; they find what is filled in, or missing.
• Saved sets stay in this browser for every model you open.

Common mistakes

• Nothing is found. A rule needs a value it can match: look at the suggestions in the value box.
• A property is missing from the list. No element with a shape in this model has it.
