Quad Level Editing

Quad Level Editing

This level of editing is used to modify faces and to create four sided faces (or quads).

"Create" (Create Quad)

This option is used to create a face or a polygon, in a new area or in the place of a preciously deleted polygon.

When this option is selected, you will get a set of crosshairs in the place of your cursor. With these crosshairs you will need to select four vertices until you have a four-sided "polygon". After you select the fourth vertex, you polygon is complete. If you cannot see the polygon, look on the other side. It may have been created with the face facing the opposite direction.

Quick Lesson: When selecting your vertices, make sure that you select them either in a clockwise, or counterclockwise manner. If you do not do this properly, a face will not be created. 

"Delete" (Delete Face)

This option is used to delete any faces that you do not want. When you select this option all of the highlighted faces will be deleted. The program will not ask for confirmation, so be careful where you click.

Quick Lesson: If you hold down the "Alt" key while select faces, you will be able to select multiple faces that aren't located directly next to each other. (Note: This applies to all of the functions that involve selecting faces.)

Quick Lesson: Be careful when selecting faces. On occasion, when you select a face, any other faces that may be behind the face you selected will sometimes be selected as well. So double check to make sure that you aren't modifying a face that you do not have any intentions of modifying. (Note: This applies to all of the functions that involve selecting faces.)

"Flip Normal" (Flip Normal)

All of the of the faces that you create while using this program are one-sided. So if you are, for example, creating a room out of a box that you have created you will have to turn all of the "walls" around because they start off facing outward. This process, of flipping the faces of an object so that they face the opposite direction, is referred to as flipping normals.

When this option is selected all of the selected faces will flip and face the opposite direction.

"Subdivide" (Subdivide Face)

This option takes any face that you have selected and "subdivides" it into four smaller, and equivalent faces that take up the same space that the original face took up. There are two different types of Subdivision; Face Center Division and Edge Based Division. Upon selecting this option you will activate a window displaying two options. You may either choose to divide your polygon with the Face Center method or you may use the Edge Based method.

Face Center Division

When Face Center Division is selected, the lines of division will come from the corners of the face, making all of the smaller polygons three-sided.

Edge Based Division

When Edged Based Division is selected, the lines of division will come from the center of all of the faces edges, making all of the smaller faces four-sided.

"Split Obj" (Split Object)

This object is used to separate specified portions of an object to form another object. 

After selecting all of the faces you wish to separate into a separate object, select the "Split Obj" function. Upon selecting this function you will activate a window prompting you to name the object you will be creating with all of the faces that you have taken from the original object.

"Hide Face" (Hide Selected Faces)

When this option is selected, all of the selected faces will become hidden from view (this option works very much like the "Hide Object" option, except that it is more specific---a face instead of the entire object).

"Hide Unsel" (Hide Unselected Faces)

When this option is selected, all of the faces of the object that are not selected will become hidden from view.

"Unhide All" (Unhide All Faces)

When this option is selected, any of the faces that you have hidden will all become visible once again.
