The surface hatch specified for a material determines the display of objects that are assigned the material in elevation and model views, as well as the appearance in rendered views. The material definition specifies which faces of objects—Top, Bottom, Left, Right, Front, Back—display a surface hatch.
However, in some instances, you may want to override the surface hatch for a selected face of an object. For example, you may want to turn off the surface hatch where it could obscure small details of an object when the drawing is plotted.
You can change the surface hatches for faces of individual objects in the following ways:
You can also specify whether the changes are applied only to the selected face or to all faces of the object with the same direction—for example, to all front faces.
You don’t need to create separate overrides for individual changes; you can create one surface hatch override that is both rotated and offset. In most cases, this is the preferred method of working. However, in some cases, you need to assign more than one override. For example, suppose you want to rotate the surface hatch of all front faces of a column, and you want to offset one individual front face. You first add an override for the rotation and select All Front Faces. Then you add an override for the offset in which you select Only Selected Front Face.
