CAD tip # 5767:

Question CAD
% platform category

Broken "exploded" hatch.

Complex hatch patterns (like wood, grain, gravel, etc.) may appear "exploded" (scattered lines over each other, parts missing) and do not display and plot properly.

The problem is that your hatch origin is probably too far from the 0,0 origin of the current coordinate system and the hatchure suffers from numerical instability. Switch to a local UCS and set its origin closer to the hatched entity (objects).

You can even fix the existing patterns by assigning the UCS (as described above), enter the HATCHEDIT command (or couble-click on the existing pattern), and when the BHatch dialog appears - simply click the OK button, and the existing hatch pattern will be fixed - no need to rehatch anything!
