Hatch problem

[Kratos]

I have a set of polylines that have a hatch within them. Whenever I assign the AR-CONC pattern, the hatch looks fine except it extends past the boundaries with these giant circles. Whenever I change the pattern to anything else, the circles go away. Also, when I change the scale of the pattern to 1.0, the hatch turns to a solid and the circles disappear. The polylines are all closed and have I tried to change the hatch origin to no avail.

 

I can't seem to upload the .dwg so I will post some screenshots.

 

Thanks.

 

1. this shows the entire drawing zoomed to extents. The circles you see are part of the hatch:

 

 

2. this shows the hatch closer. those white specks you see are part of the "circle" created by this problem.

 

 

3. This shows what happens when I change the pattern or the scale. Notice the specks are gone and when I zoom extents, it zooms to the extents of the objects I am trying to hatch.

 

 

I hope this is enough to clarify the issue I am having. if not, I will try to upload the .dwg file later when I have more time

Is the pattern actually changing to a solid type hatch in the properties? Often when you zoom out the drawing will re-scale to suit the view and not regenerate until you type REGEN (RE) or REGENALL (REA)

[Kratos]

It lists as AR-CONC even when it appears to be solid. Regen or regenall doesn't change anything.

 

Cue Twighlight Zone music.

Delete about 95% of the drawing just leaving a couple of the objects you were trying to hatch along with the hatching itself. Use the Save As command and save the drawing under a new name. Attach a copy of the drawing to your next post. Someone here will take a look at it.

Can you post the Images and a Stripped down/-PURGED drawing with just the problem hatching to CADTutor?

 

Where is the hatch origin in relation to the hatch?

[Kratos]

I purged the drawing and saved it under a different name. The drawing only contains the hatch and the polylines that were used. i have attached the drawing.

 

Thanks

I think that you may be using the Hatch command beyond the limits that it was written for, particularly with hatch patterns that have a lot of detail. I keep on getting the message "Hatch pattern too dense".

 

Hatching always used to be confined to what you saw on the screen, and if you zoom out to see 7km of dual carriage road, AutoCAD is struggling with screen definition.

 

Those are my thoughts and may not have anything to do with your problem, but I would split up the areas into a screenful at a time

ODD, I changed the Angle to 90° and it looked fine on my computer.

are you trying to hatch in paperspace or modelspace? sometimes with certain hatches i need to do the hatch in p-space, then change it to m-space.

Doh! I never tried that but it worked.

 

I'd still like to know what caused the issue though. In 10 years of using CAD, i have never seen that before.

 

Thanks for everyone's help. Much appreciated..

Model space.
