Hatch and Line Type

The two commands that give a 2D drawing its drafting conventions: hatching to show solid metal in a section, and line types to tell a visible edge from a hidden one. Both are Rhino commands, gathered on the Drafting tab.

Hatch

Hatch runs Rhino’s Hatch command and fills closed planar curves with a pattern: select the boundary curves, then choose the pattern, scale, and rotation in the hatch dialog.

On a jewelry drawing its main job is the cut section — the diagonal lines that mark where the metal is solid. Hatch the section curves you get from Clipping Sections or Make 2D, and the drawing reads at a glance.

For more information, please refer to the Rhino documentation.

Set Line Type

Set Line Type runs Rhino’s SetLinetype command and assigns a line type to the selected curves: select them, then pick a linetype — dashed, dotted, center, hidden — from the list.

This is how a flat Make 2D drawing gets its conventions: hidden edges dashed, symmetry axes as center lines. The line type is a display property of the curve — if you need the dashes as real, separate curves, use Extract Line Type Segments.
