Hatch boundaries not matching the object selected

[Anonymous]

I have been hatching polylines using the select object option, but the hatching is adding in extra nodes and does not follow the shape! What is happening? I am working in AutoCAD 2016, the shapes are simple and 2D polylines. In addition, I cannot seem to get rid of the extra hatch edge ghost after I've deleted the hatching, to go back to the simple polyline. Can anyone help with these problems? Pictures supplied!

Try using REGEN when you are zoomed in and see if it makes a difference. If it does you can see about increasing your VIEWRES so it doesn't look out when you zoom in.

Unfortunately regen makes no difference. The line looks fine till you select it and stays exactly the same after regen

Hi and Welcome to AutoCAD Forum,

such a problem will resolved easier if we have the dwg file ... is it applicable to attache here part of your CAD dwg please ?

Sure, any help gratefully received.

HI

TRY REGEN, REDRAW, REDRAWALL COMMAND (AFTER ZOOM IN) TO SOLVE THE UNUNIFORM HATCH.

SET THE HATCH ASSOCIATIVE TO NO IN PROPERTIES (CTRL+1) (to see all vertex)

Sadly, no, the redraw everything doesn't work, nor does removing the associativity. see screen dump attached.

Hi @Anonymous,

I see that you are visiting as a new member to the AutoCAD forum. Welcome to the Autodesk Community!

Is it possible to attach your drawing file so I can try to duplicate this behavior? I see this sometimes when the objects being hatched use splines.  The way I usually can get it to work is to make sure that the object is flat using flatten.  If possible I also convert the spline to arcs and lines and then join them in a polyline.  You can also try to recreate the boundary using BO (boundary and then hatch the new boundary.

Hi John, I've attached the file (it didn't appear on the forum last time). Hope one of your solution helps!

Hi @Anonymous,

I don't see the attachment. Can you try again - perhaps use a different web browser?

Hi all,

I'm now on my third browser so I hope this works! I've tried all of your solutions but none of them seem to make any difference. Here's hoping you can see the file!

Hi,

for me ... every thing is OK . i have not notice any bad edge issue . i don't know why your dwg file when i open it was NOT in a 2D wireframe visual style !!!

Hi,

>> I've tried all of your solutions but none of them seem to make any difference

For me it does.

• The visual style you have set "Wireframe" shows the issue"
• When using visual style "2D Wireframe" it does not show that issue.

...as shown here:

You might also try to disable hardware acceleration, but at least it's just a display issue, plotting should look correct!

Hi,

btw: copy and paste the geometry into a new drawing also solved that issue on my system.

[EDIT] sorry, did it not, save/close/reopen showed the same effect [/EDIT]

- alfred -

PS: it might be easier, if you don't create one hatch for all polygons, makes it more easy to edit the hatch(es)

[imadHabash]

another two issues :

• when i separate your hatch ( Hatch Edit ) i notice that you have duplicate hatched for the same area. try to clean it and see if any chages.
• your drawing is too far from 0,0,0 ... please keep near 0,0,0 to avoid any troubles . 

please ... see attached file and see if any changes.

Thanks all for your help, I have really appreciated it - the wireframe setting sorted it! But Autodesk take note of this weirdness!

Thanks for the tip on the 0,0,0 but this is part of survey data from a very large site, so the skeleton is georeferenced - could be worse, could be six figure OS coordinates!
