When adding a hatch to a drawing, Advance CAD fills entities or enclosed areas with a specified pattern. The user can choose between a predefined or a custom-made hatch pattern.

Hatch patterns are memory-intensive, therefore they should be added during the last steps of drawing creation. They could also be inserted to a separate layer which can be closed as you continue to work on your project.

You can add hatching to any entity as long as it forms a closed boundary. Single and multiple selection of elements are permitted.

The steps below follow a general method for creating a filled area in a plan view:

1. Select “Hatch” from the Draw panel of the Home ribbon tab to access the Boundary Hatch dialog box

2. In the Boundary tab of the dialog, look for “Island Detection Options” section and choose one of the following:

  • Nested Islands – the outer entity and all its islands are considered for hatching;
  • Outer Only – only the outer entity and its outer island are considered for hatching;
  • Ignore Islands – only the outer entity is considered for hatching.

To keep any new elements that are created for drawing the boundary hatch, select the “Retain Boundaries” option.

Note:

Existing entities are always retained.

Select Objects – this option is used for selecting entities created by polylines and shapes.
