You cannot place a person in a certain area of the scene
Cause 1
When you add a person on the scene, the application checks that nothing can prevent this person to evacuate from the place where you are placing them.
Therefore, if a certain object is already located in this place, you cannot add a person there.
Solution
- Check the topology and find an object in the area where you want to add a person.
- Edit object properties so that the object does not interfere with the placement of the person.
Typically, this object can be a floor slab located on the underlying floor, and the upper level of which is higher than the level of the floor on which the person is placed. Since the floor slab is not visible when adding a person, you need to switch to the floor below to adjust its level.
Cause 2
When you add a person on the scene, the application checks that the height of the free area above them is not less than the minimum threshold height of escape routes. For more information, see Evacuation Simulation Parameters.
Solution
- Check the topology and find the object with the following properties: the distance between its lower level and the level where you want to place a person is less than the minimum threshold height of escape routes.
- Edit object properties so that the object does not interfere with the placement of the person.
Typically, this object can be a floor slab, which, for convenience, is usually hidden during the placing of people.
The application checks that nothing prevents a person from evacuation only at the time you add the person. If changes that prevent a person to evacuate, are made to the project later, there will be no warnings about it.
