Use hatching on part faces, part sections or drawing shapes, such as circles and polygons, to show different materials.

The hatches are located in the hatch_types1.pat file in the …\Tekla Structures\<version>\environments\<environment>\inp folder. You can also use hatch patters on surface treatment.

You can also add custom hatches in the hatch_types1.pat file, see Adding custom fill patterns.
