A step by step walkthrough on how to make a hatch like this would be appreciated:

If you try to edit this hatch look at the levels and the settings for each

It is hard to believe creating hatches in VW is so difficult

Have not had time to try it but I wonder if you drew what you wanted to in VW - could you get the line lengths angles etc and take them back into Edit Hatch - Build Hatch whatever it is called - dunno

I have mainly avoided the Hatch Builder as it does my head in

Once used some cad software - anything you drew could be saved as a hatch - took some trial and error though

We have a command in our version that makes a hatch based on the selected lines and a selected rectangle wich is the repeating space. Doesn't have the US version this?

if it doens't have it, I would be happy to make it for you. Just tell me how big the circles needs to be approximatly and how much space between them.

Dieter, that command must be part of your local customisation because it isn't in the North American or the Australia/New Zealand versions.

There are probably many useful capabilities like that lurking in the different versions where local customisation occurs. Its a pity they can't be made available to a broader market as pay for add ons.

Christiaan, it really isn't that difficult, it's only an annoying thing to do, but in less then 5 minutes, you'll have your hatch with only 12 levels.

• for your first lever, fill in these values:
  Start Point
  L=0mm
  A=0?
  Repeat
  L=3mm
  A=0?
  Dash Factor
  Factor=0,1
  Offset
  L=3mm
  A=0?
  
• Duplicate that level (Add Level), move its Start Point to the end of the dash of the previous Level (1) and count +60? with the A's of Repeat and Offset (add it first to the Offset, otherwise you'll get an error message). So you'll get:
  Start Point
  L=0,3mm
  A=0?
  Repeat
  L=3mm
  A=60?
  Dash Factor
  Factor=0,1
  Offset
  L=3mm
  A=60?
  
• repeat the previous step until you'll have full 6 Sized Regular Polygon (or whatever it is called in English).
  

Ok, so now you have a quite repetitive hatch. We'll add an other "circle" to the hatch that will break the pattern.

• adjust the pen colour of the 6 Levels, that way you'll have visual control of what the "old circle" and what the "new cirle" is.
  
• Duplicate the first Level and give it an other colour
  
• the Start Point doesn't matter now, put it somewhere you like.
  
• Make the Repeat and Offset 2x bigger but the Dash Factor 2x smaller. Give that line an angel of 15?. So you'll get this:
  Repeat
  L=6mm (this is now 2x bigger then the previous "circle")
  A=15?
  Dash Factor
  Factor=0,05 (this is now 2x smallerthen the previous "circle")
  Offset
  L=6mm (this is now 2x bigger then the previous "circle")
  A=75?
  
• And now again, duplicate that Level, position it at the end the previous Level and add 60? to the A's of Repeat and Offset.
  
• repeat previous step until you have your "circle".
  

And there you have your hatch, now you can give it on other colour if you want.
