Radial Hatches...

[Anonymous]

Is it possible to do "radial hatches", such as brick within a circle
giving - for that matte, is it possible to do a spiral hatch - you know,
like the yellow brick road?! Seriously, I need a radial (concentric circles)
brick pattern.

If you understand the syntax of the .PAT files, you can.

Have you done a google search for 'free autocad hatch patterns'? One of the great strengths of autocad is that if you have a need, someone else has probably created a solution.

Alternately you could use a super hatch (express tools).

Any recommendation on "free" patterns; most I've found are hatch patterns
"for sale".

a radial pat would be extremely difficult, IMO and as concentric...whew

I might try a spiral.lsp and work from there, with possibly an array for
other lines

Hatches must repeat a defining motif along two different straight axes so
that the generated pattern can cover an infinite plane. A polar or radial
pattern does not actually repeat along straight axes, so it is not possible
to create a generalised radial hatch pattern.

However for small areas you can create a hatch pattern motif large enough to
entirely cover the required area without repeating the pattern which can be
placed in drawings by adjusting the hatch origin at each insertion - as an
alternative to creating a macro to place and trim blocks against the area's
boundary. The attached HatchKit-created circular pattern of 230x76mm bricks
is just over 4.5 metres in diameter. http://www.cadro.com.au/hatchkit/

Hugh, that's great, I guess. I tried to use the hatch, but at a scale of 1
it was far too big, and when I tried to change the scale it disappeared
altogether. But I appreciate your efforts, explanation and "freebie".

That pattern was in metric (mm) units.

You can rescale hatch patterns outside AutoCAD:
- Excel. Scale all numbers (except the first) in each line by the same
factor
- this utility www.r-e-d.co.nz/revit/PatternScaler.html
- or HatchKit www.cadro.com.au/hatchkit

I can post a scaled version if you nominate a scaling factor. What units do
you work in?

Thanks for the offer Hugh; inches and feet please.

Happy to. Both inches and feet versions as well as the original metric
version are in the attached .zip file.

It's probable that a very large hatch (as these are) is quicker to refresh
than a very large number of (trimmed) block instances. I think the hatch is
quicker to insert in the first place, and so long as it covers the area is
worth trying out.

BTW There's a third-party package out there that does brick paving if you
have serious requirements. I haven't tried it out.
