Change the level of an element

[FRFR1426]

How can I change the level of an element? Level property is read-only...

There is a trick or a hidden method somewhere?

Hi,

instead of setting the level *property*, you could try to set the level *parameter*.

Depending on the type and category of the element you want to modify, you could set the BuiltInParameter.FAMILY_LEVEL_PARAM (for FamilyInstances), for example.

Use RevitLookup to get the level parameters for other kinds of elements.

Level params usually are set with an ElementId:
