The View Menu

The purpose of the functions in this menu is to control what does and doesn't appear in the editor's 3D and 2D views. For more ways to customize the appearance of the Valve Hammer Editor, refer to the sections on the General, 3D View, and 2D Views options.

Screen Elements This sub-menu allows you to show and hide Hammer's toolbars.

2D X/Y, Y/Z, X/Z
Selecting any of these will turn the currently selected view into whatever you've selected: X/Y (top), Y/Z (front), or X/Z (side) view.

3D Wireframe, Filled Polygons, Textured Polygons
Selecting any of these will turn the currently selected view into wireframe, filled polygons (flat shaded colored polygons), or textured polygons (textured as they would be in the game).

Autosize 4 Views
This function only works when you aren't using independent windows. The four views will be set to equal sizes based on the current available screen space.

Center Views on Selection
Choosing this function will center all of the 2D views on whatever you currently have selected.

Show Connections
Choosing this function will cause lines to be drawn in the 2D views between entities and their targets.

Hide Items and Hide Paths
These functions are used to hide items (any point entity, actually) and paths (which are created with the path tool).

Hide Selected Objects
This function is to hide the currently selected object. Doing this also places the object into a VisGroup which can then be shown or hidden using the Filter Control dialog.

Show Selected Objects
This function makes all hidden objects visible.
