This offer is not only for Map 3D, but for AutoCAD in General. But I don't see an opportunity to create an idea for AutoCAD...
Remove the BHATCH limit for reading custom PAT hatch files — only one.
Allow BHATCH to read PAT files where any number of pattern is described.
First, acadiso.pat describes any number of pattern.
Secondly, the Design Center reads a pattern from a file where several are described.
Thirdly, by analogy with descriptions of custom line types - any number can be described in them.
The main thing is that there are no objective reasons why this restriction in BHATCH applies.
Only "historically" - atavism. But this restriction may interfere with the work. And store a library of hatching in a single file is convenient.
