CAD tip # 7060:

Question CAD
% platform category

Cannot hatch an object enclosed by a zigzag line (AMZIGZAG).

If you have closed a drawing object with a zig-zag line (AMZIGZAG) and and now you try to hatch it in AutoCAD Mechanical, you will fail.

The reason is that the AMZIGZAGLINE command creates a zigzag line in the layer AM_4. Object in the layer AM_4 are ignored as valid boundaries in the Mechanical hatch commands (AMHATCH, AMUSERHATCH).

You can solve this by temporary moving your zig-zag lines (or other contents of the AM_4 layer) to another layer. After you hatch the objects, you can return them back to the layer AM_4. You can also use the standard AutoCAD hatch command - BHATCH, which respects the drawing geometry independently of layers.
