Constraints

The Constraints section in the Rhino Properties panel lets you control whether objects will be linked or not to levels and guides.

Link to guides

When this option is checked, the object may get linked to a guide and move along with it, according to these conditions.

Link to levels

When this option is checked, the object may get linked to the elevation of a level and move when the level elevation is edited.

Objects will only move if the Constraints icon in the Level Manager is enabled in the level where the objects are located.
