Hammer Entity Tool
This tool allows you to place point-based entities in a map. Point-based entities are those entities which exist only at a point, and do not rely on a brush for their effect. Once the Entity Tool is selected, the New Object Dialog (see Hammer New Objects Toolbar) will contain a list of entities from which to choose. Click on one of the 2D views and press Enter to place the entity. If Snap To Grid (see Hammer Map Menu) is enabled, the new entities will be snapped to the grid.
Note: In order to place a brush-based entity (a func_door for example) you must first create the brush with the Hammer Block Tool. See Tie to Entity in the Hammer Tools Menu, for more information on brush-based entity creation.
See Creating Entities for more information on creating both point and solid entity types.
