Hatch Pattern with Circles

[bmckenzie]

Is there a way to create a hatch pattern with an array of circles? We do a LOT of drawings with thousands of tiny circles representing perforations and it is eating up our system memory. I hope making them into a hatch will help.

Thanks,

you could make a block of your pattern and then use superhatch from express tools.

Quite good circles can be achieved in a hatch pattern by utilising a set of approximating straight lines.

What is the circle diameter and how is it to be arrayed?

[bmckenzie]

W use 5mm, 6mm, and 8mm diameter holes at 16mm and 32mm O.C. I think we figured out a work around though. For our overall RCP drawings we are using a "+" hatch and only using the circles on the enlarged details. It saves quite a bit of regeneration time.

You also could consider making a drawing with the circles that is referenced and then clipped.

The complete yen is impossible, but push forward a polygon; can do it.

I made this routine, I think you may find it useful...

Only limitation is that it works only on closed 2d pline - it doesn't work on circle or region as boundary for hatching with concentric circles...

[marko_ribar]

When I mean it don't work on circle as hatch boundary, I was thinking if you pick circle and input hatch origin as center of circle... In all other cases it works with circle or ellipse or any 2d polyline...

I'll send these hatch patterns, that can be combined with concentric circles very well...
I named them ray-1, ray-2,.., ray-22.5, depending on angle between rays in hatch...

Thanks Adii for the circle patterns
