Editing Hatch Definitions

To edit the hatches available for materials and samplers, click Tools-Edit Hatch Definitions from the main menu to display the pattern editor.  The hatch definition editor has two tabs: Patterns and Line Weights.

Definitions

An individual hatch definition can be viewed, and to some extent modified, by selecting it on the list at the left of the screen.  Note that at the moment hatch editing is limited to editing the scale factor, whether the hatch is filled, the default width, rotation, and overall line weights.

Patterns Tab

Scale Factor

Adjusts the scaling of the hatch.  A larger scale factor "zooms in" on the hatch, while a smaller scale factor "zooms out."

Filled

For hatches with shapes (such as gravel), selecting this will fill the shapes.  Leaving it unchecked results in hollow shapes.

Default Width

Defines the line width used in the hatch.  These values are specified in detail on the Line Weights tab.

Rotate

Rotates the hatch, in degrees.

Line Weights Tab

The line weights are used in hatch definitions to define line thicknesses, and are defined with a nickname (e.g., "thin") and a thickness, which should include the units (e.g., "0.0075 in").

The hatch definitions can use these nicknames to define their line widths.  For example, the hatch "downleft_thin" uses a default line width of "thin," as do many other definitions.  To change the line width in all the hatches you could edit it in each definition, but to save time you could just change the definition of "thin" here.

To edit an existing weight, edit the name and/or thickness directly in the cell.  To add a new weight, click in a blank cell and enter the name and thickness.

IMPORTANT:  To restore a line weight to it's default value, leave the name of the weight as is, but delete the thickness.  The next time the hatch editor is opened, the default thickness will be in place.
