skew a hatch pattern??

is it possible to skew a hatch pattern. for instance on a roof that your
look at from an angle...

 

Nope.

 

Not sure what you mean by "skew". If you mean rotate, then yes, you can do
that. It won't stay within its original boundary, but you can rotate the
hatch object.

If you're working in 3D, then we need more info.

 

unless he gets into 3d rotations...(drawing is 2d, hatch is 3d.. done
that a few times.. hard, but it works)

 

Easily done using UCS, ROTATE, HATCH & FLATTEN commands.
UCS > X > 90
Go into a 3d view now
ROTATE > Select hatch bndy > pick a "fixed" corner > Enter angle (45?) +/-
really doesn't matter
UCS >3 (to align UCS with hatch bndy)
HATCH
UCS > World (and then PLAN if UCSFOLLOW is OFF)
EXPLODE (the hatch)
FLATTEN (the resulting entities)

It sounds more complex than it is becuase once you've done it a few times
the whole process takes a matter of seconds to complete

 

That might get easier with repetition, but I'd call it a fairly complex
workaround, and the result isn't a hatch anymore. I've done essentially the
same thing, and found that I could no longer hatch the whole roof because
the file size was inflated so radically. Just showed the non-hatch pattern
on a small area instead.

I think the responses have borne out my initial short reply: no, you can't
"skew a hatch pattern" with the tools that come with Acad. There's a good
aftermarket solution, and there are workarounds that will achieve the same
appearance, but there isn't a "skew" factor available in a hatch entity.

 

WOW, have a response or two...
Fortunetly the roof in question is small ( a small octagon bump-out.) and
I've only got 2 small roof plans to worry about, so I've been able to make
it look good using an old shingle block I had from long ago..Thanks agian.

Maybe some of the ACAD folks could put that on the "wish list"....

So skip the EXPLODE & FLATTEN commands. You stil have a hatch object and
file size considerations are reduced.

It would be a good one. When we confronted this, we were doing a series of
buildings that had clay roof tiles on hip roofs on angled wings of the
buildings! It was a nightmare just to get a reasonably realistic texture on
small bits of the roofs.

 

There's no conceptual barrier to applying a full transform to a hatch as
it's inserted rather than just the currently available controls: global
scale, origin movement in X and Y and rotation . Adding 3 more controls. (Y
scale, X and Y shear) would give you what you need for even the fussiest
roof.

Excellent setup. ;-)
