Check a model for common problems

What you'll do

Look over a model before you hand it on: the problems that break schedules, quantities and other people's software.

Steps

1. Open an IFC model.
2. Open Model checks in the left panel.
3. Under Required properties, choose a class (or Any class) and a property every element of it must have. Click Add a property for more. They stay in this browser for every model.
4. Click Run checks.
5. Click a result to pick those elements and zoom to them.

What you should see

• Missing a required property: each rule with the elements that have no value for it.
• GlobalId used twice: elements sharing one GlobalId. Other software treats them as one element.
• On no storey: elements with a shape that no storey contains.
• Copies on top of each other: elements of the same class and type with the same shape in the same place, which count twice in quantities.

Good to know

• Checks look at the active model when several are open. See See several IFC models together.
• After an edit, run the checks again.

Next

• Find elements by class, name or property
• Delete, cut, copy and paste elements
