Hatch "boolean union" - feature request

Today it is possible to trim hatches, which is a great help.

But when you want to extend hatches to adjacent geometry … there seems no really good way of doing it. (At least humble me does not know of it…)

One can use Curve Booleans to join adjacent pieces of geometry into a new shape and then hatch that shape. (But if there is already a hatch, that hatch then needs to be deleted etc …)

Or turn on the Hatch boundary and manipulate that, which is sometimes usable, but in most cases quite cumbersome, especially when you need to add points to the the curves etc.

It would be great to have an “ExtendHatch” which would work like Curve Boolean adding closed pieces of linework to an existing hatch. Would save eons of time when doing nice and complex 2D-drawings.

While talking about hatches … maybe the default hatch library of Rhino could be a bit extended. 9 hatches is not a lot … Could have some basic material hatches (wood, steel etc …). Just for those basic needs.

Thanks

There are tons out there for free download - I often use CadHatch.com. Add them to your default templates and save them, then you will have them in every new document. Import the file with the hatch patterns into an existing document and they will also come in.

Sure I use them as well.

But I still think Rhino could include a couple more default hatches.

Hej Erik -

We have that feature request on the list as RH-63689 Hatches: Boolean operations

… and this one as (not public) RH-75177 [Additional Hatch Patterns]

Hi @erik6,
For ideas on how to access additional hatch patterns for Rhino, see this web page.
