Custom Hatch Pattern

I have a block file that I would like to turn into a hatch.pat file. I know I can use super hatch in the express tools, but I find it hard to work with, plus not everyone in the office knows how to use it.

If anyone could help me out with this it would be great. I'm not even sure if it can be done.

I'm attaching the block file and what I have so far for a PAT file.

Thanks in advance for any help.

I added a picture and a dxf file (that just needs the .dwg removed).

Hi Matt,

a rectangular template as required by Express Tools would be lcm(36.5,20.25) = 2956-1/2" wide to allow all of your blocks to repeat properly.

Splitting the template between tall blocks and thin blocks allows their respective horizontal repetitions (and pattern size!!) to be reduced while sharing the same vertical spacing, viz:

How-to with HatchKit:

1. load DXF
2. delete all but one shallow block
3. delete all one one wide, one narrow block from each row of tall blocks.
4. arrange vertical spacing to 26"
5. create new layer.
6. copy all content to new layer.
7. delete tall blocks from first layer, shallow blocks from second
8. arrange horizontal spacing to 36.5" for tall block layer, 20.25" for shallow blocks.
9. save pattern to AutoCAD format.

I hope this helps,
