When I reopen a saved drawing, hatch patterns typically skew, requiring me to redo them from scratch.

[jadiemaze]

I've been experiencing this issue for years now, and nothing I've found online addresses it.

Whenever I close the program after saving my work and then reopen the drawing I was working on, multiple hatched areas will display skewed.  The hatch pattern will have burst out of the boundary and be broken up and missing patches, like a puncture wound with blood spraying out across a carpet.

How can I protect my hatched areas from rupturing so that I can save all the time it takes me to re-hatch the areas where the leakage occurs?  Note:  I've checked my boundaries and there are no gaps, and some but not all hatched areas burst and spew patterns in my drawings; maybe there are ways to draw complex shapes and areas that prevent this?

Any insights and especially step-by-step instructions for fixing this issue would be greatly appreciated.

Is your save settings under Options set to save to the current dwg format or to an older dwg format?

[VincentSheehan]

Are they custom patterns and are you picking a point or selecting and boundary? Also, I know you said, there are no gaps. Are there any overlapping or crossing polylines within the boundary?

[jadiemaze]

I don't know about saving to a specific format.  I just click save or save as and it's always .dwg

These are standard hatch patterns.  There are at times other lines crossing the selected boundary.

at the command prompt enter command Options 

select Open and Save tab

Under File Save what is the Save as format:

@jadiemaze Never seen that happen before, sorry it has been happening to you for years now.

How do we replicate it? start with hatch pattern name, if it's annotative or not, if it's associative or not, was there a boundary when created (I'm not sure if there is one solely for the pattern in your screenshot), is there a frozen of off layer that perhaps should not be?

OR...

Can you share that portion of your DWG file with the "skewed/ruptured" hatch?
Then can you share with us that portion of the DWG file "after you fix it" along with a screenshot showing us that it "got fixed"?

TIA

Could it be a bad hatch pattern file? acad.pat

It doesn't seem to me that any of the suggestions so far [file format differences, pick-point vs. boundary object, off Layer object(s) crossing the area, bad pattern definition, etc.] nor anything else that occurred to me to ask about [such as Z-level differences] can be the explanation.  If you made Hatch patterns successfully, and they're right when you Save and get out of the drawing, but wrong when you re-open it, none of those things apply, or you would not have made them successfully in the first place.  I wonder whether it's the program, and you may need to re-install AutoCAD.

What if you select the hatch and click Recreate to recreate the boundary as a associated polyline?

@jadiemaze ,

Welcome to the forum!

The suggestions from these links may help:

• Hatch patterns do not display, preview, or plot correctly in AutoCAD

• Hatch extends beyond ... boundaries in AutoCAD

• Hatch patterns ... appear distorted

As last resort, perform a Clean Uninstall before reinstalling.
