Hatch fills

You can fill objects with hatch patterns to clearly distinguish materials or object relationships in a drawing. For example, a drawing of a floor plan may use hatching to indicate different flooring materials, or to indicate where two floors overlap.

Hatch fills can be used to indicate different materials.

Hatch fills are composed of vector-based lines. You can use preset hatch fills or edit fills by setting different line patterns and colors for the foreground, or by changing the color of the background. When you edit hatch fills in the Hatch fill dialog box, the changes apply only to the currently selected object. You can also create new hatch fills and add them to a library.

When you create new hatch fills, the currently selected fill is used as a starting point. If no fill is selected, the default fill is used. You can add new lines, specify line style attributes, set the position and angle for the lines, and control the spacing and offset for each instance of a line.

You can use hatch fills on projected objects to create the illusion of a three-dimensional image. Hatch fills use the active drawing plane.

Transforming and scaling hatch fills

Hatch fills can retain their properties independently of changes made to the object, or they can be transformed and scaled with the object. If you choose to transform the hatch fill with the object, only the transformations you apply from that point forward are applied — previous object transformations are not applied to the hatch fill.

The original hatch fill (left) isn’t scaled with the object in the first example (center) and is scaled with the object in the second example (right).

Aligning hatch fills

When you apply the same hatch fill to more than one object, you can retain the fill alignment for the individual objects, or you can align the fills.

The hatch fills are aligned in the drawing on the right.

To apply a hatch fill

2 .	Click Edit Properties.

3 .	In the Properties docker, click the Hatch fill button to display hatch fill options.

4 .	Click the Hatch fill properties button .

When you edit a hatch fill in the Edit fill dialog box, the changes are applied only to the object selected in the drawing window. Only custom hatch fills created in the New hatch from selected dialog box can be added to a library.

You can also apply a hatch fill by clicking the Interactive fill tool in the toolbox, choosing Hatch fill from the Fill type list box on the property bar, and specifying the properties you want.

To create a custom hatch fill

1 .	Click Window Properties.

2 .	In the Properties docker, click the Hatch fill button to display hatch fill options.

3 .	Click the Hatch fill properties button .

You can also
Add lines	Click the Add button . When you add a new line, it is created directly over the previous line. Change the y-Origin value to view the new line.
Delete lines	In the Hatch lines list, choose a line, and click the Delete button .
Hide or show lines in the Hatch preview window	In the Hatch lines list, click the Eye icon to the left of the line name. When the eye appears closed, the line is hidden. When the eye appears open, the line is displayed.

To scale or transform a hatch fill with an object

2 .	Click Edit Properties.

3 .	In the Properties docker, click the Hatch fill button to display hatch fill options.

4 .	Click the Hatch fill properties button .

To align hatch fills across multiple objects

2 .	On the property bar, click the Fill button , and choose Hatch fill dialog.
