Hatching Overview

When you add hatching to a drawing, Bricscad fills entities or enclosed areas with a predefined pattern or lines. First you specify the hatch pattern and other options, and then you choose which entities or enclosed areas that you want to hatch.

NOTES

Depending on the pattern, hatchings are memory intensive and might take a considerable amount of time to draw and display. To improve performance, add hatching as one of the last steps when you create a drawing, or insert hatches on a separate layer that you can freeze as you continue to work on your drawing. Or use the FILLMODE system variable to switch off the display of hatches, gradient fills and filled entities.
Hatches that are too dense, are not displayed. If such hatches exist in a drawing, a warning displays in the command bar after opening the drawing. The maximum number of dashes is controlled by the MAXHATCH settings variable. By default the maximum number of dashes is 100 000.

The pattern files sit in the Support folder of the current user.

The MEASUREMENT setting controls which hatch pattern file will be used.

Imperial: uses Default.pat
Metric: uses Iso.pat

NOTE	Custom hatch pattern files are not yet supported, though custom hatch patterns can be added in the Default.pat and Iso.pat files.
