How to explode dot hatches

Most hatches can be exploded but not the dots…
cannot even make2D or DupBorder

Dots are not hatches. Dots “live” in screen space - not in model space. Their size is fixed in pixels, and doesn’t change with the model size or zoom level.


It means I have to make the sand patterns with circles not dots ?

I’m not sure what “sand patterns” are

but if you need something that can used as actual geometry in model space, do not use dots.
If you need text, use Text; if you need text as curves use _TextObject; if you need circles, use _Circle, etc…

OK, looks like I misinterpreted your request - you want to explode hatches composed of entirely dots (points), not Dots created with the dot command… sorry. It looks like Rhino cannot currently do that - neither V5 nor V6. I would have thought that Rhino would just create point objects, but that is not the case.
