Topic: Hatch problem

[42]

Have a look at this drawing of a hatch problem. The one on the left is correct. What has happened to the righthand one?
http://theswamp.org/lilly.pond/42/hatch.dwg
It seems to be broken, the effect is the same for all hatch pattens.

I don't know, but using match fixed it.

[42]

Unfortunately using match does not fix it on my machine, although I match the left one into the right one.

[Craig]

One thing I noticed about the two is the following
One on the left
(70 . 0) (71 . 0) (91 . 4) (92 . 5) (93 . 4) (72 . 1)
One on the right
(70 . 0) (71 . 1) (91 . 1) (92 . 1) (93 . 4) (72 . 1)

71 - Associativity flag (associative = 1; non-associative = 0)
91 - Number of boundary paths (loops)
92 - Boundary path type flag (bit coded):0 = Default; 1 = External; 2 = Polyline;4 = Derived; 8 = Textbox; 16 = Outermost
--------------------------
72 - Edge type (only if boundary is not a polyline):1 = Line; 2 = Circular arc; 3 = Elliptic arc; 4 = Spline
93 - Number of edges in this boundary path

When I redid the same hatch on my machine they came in identical
(70 . 0) (71 . 1) (91 . 1) (92 . 1) (93 . 4) (72 . 1)
(70 . 0) (71 . 1) (91 . 1) (92 . 1) (93 . 4) (72 . 1)

Hope this helps some

That’s beautiful Craig, but I do not have a Scooby Doo what it means. Well yes I know that it refers to the hatch construction, but beyond that no clue. The hatch works fine in other drawings.

[daron]

audit the drawing?

[42]

Yep done that

[daron]

wblock it to another name and rename?


Lastly, start over?

[42]

Done that but no dice on effect on the hatch.
Not an option 3.5MB drawing.

I noticed that the one on the right is associative.
Your Scale factor does not work for me. Maybe my
arconc hatch is different but when I edit the hatch on the right
change the scale to 20 it redraws as correct.

Have you tried deleting the bad hatch, redrawing its boundary, then re-hatching it as non-associative. It seems to be associative when listing it, but doen't appear to be associative when selecting it.

[Craig]

Well I found something else that might be your problem. Did you create the rectangles differently? Notice the difference between the two LWPOLYLINE's?
The left one
((-1 . <Entity name: 40a0be30>) (0 . "LWPOLYLINE") (330 . <Entity name: 40a86c10>)

The right one
((-1 . <Entity name: 40a0be20>) (0 . "LWPOLYLINE") (5 . "9AC") (102 . "{ACAD_REACTORS") (330 . <Entity name: 40a0be28>)
---------------------------
102 - Start of application-defined group "{application_name". For example, "{ACAD_REACTORS" indicates the start of the AutoCAD persistent reactors group. This group exists only if persistent reactors have been attached to this object.

I rehatched both areas in the original drawing using associative and non-associative hatching, it makes no differance.
Daron, this also makes on differance. I can draw a new hatch boundary and either hatch it by point or object. What is frustrating is that hatching done earlier is fine.

[42]

Craig. I can copy a rectangle that containes correct hatch, rehatch the second rectangle and obtain the incorrect hatch.

[daron]

It seems that you have something setting reactors in your drawing, as Craig pointed out. I had your drawing open and was in here. I went in to cad and noticed it had frozen up. Has anybody else experienced this?

List your rectangles. Are they containing any reactors? Are they both unassociative?
