Problem with hatch pattern

[Anonymous]

I have a problem with the hatch command. I want to fill the polyline with a grass patern but for some reason it shows me this (see screenshot). The grass marks from the hatch overlap with each other. Even when i adjust the scale it doesn't give me the pattern i want.

You need to change you hatch scale most likely.

perhaps you can post your dwg file so everyone can help troubleshoot easier?

Hi

Check your  hatch name it must be grass .

see attached

 

if everything is correct ,open acad.pat with notepad

search for Grass,it must be like this

*GRASS, Grass area
90, 0,0, .707106781,.707106781, .1875,-1.226713563
45, 0,0, 0,1, .1875,-.8125
135, 0,0, 0,1, .1875,-.8125

you can overwrite this 4 line on yours.

save and close re open the file,if still you have problem

upload your cad file.

good luck

Most likely it's a setting i've to adjust, i get the same result in my other dwg-files

Copy the red PLine and hatch it. it works fine.

There seems to be a gap between your red and green PLines in the sharp corner on the right.

Close this gap and you have a closed parameter and the hatch will not overlap.

Or (depends on the AutoCAD version you are using) set the HPGAPTOL to a higher value.

For me, I had to explode the red PLine to get the hatch to fill.

Nothing changes if i close the polylines. The problem is the objects that make the hatch pattern (for ex. the cross) are way to large, so that the crosses overlap, making the hatch look like a grid. Scaling does not help (see screenshot). On the lift is the cross pattern with scale 1, on the right with scale 0.1.

That looks very much like a corruption of the pattern definition, specifically as though the dash-and-gap specifications [a positive number followed by a negative number] at the end have been removed or commented out or something, so that all lines are unbroken.  Open up the acad.pat file and look at what it has as a definition for the CROSS pattern.  It should look like this:

*CROSS, A series of crosses
0, 0,0, .25,.25, .125,-.375
90, .0625,-.0625, .25,.25, .125,-.375

That definition performs as expected for me.

HI

your cad file was ok see it on my computer

-what is the result when you are printing that file  ,is it same as autocad screen or different?

-cheek your file in layout 

see picture

-if its different, maybe something wrong with  g.c !

good luck

The pattern stays the same in Layout.

Changing the acad.pad could be an option but i have tis problem for all of my patterns. Also is use AutoCad from a shared server. Wouldn't it be a better idea to create a new hatch pattern?

The defect of that GRASS pattern seems to be inside your ACAD.PAT (or ACADISO.PAT), not sure which one is accessed by your AutoCAD, depending on MEASUREMENT setting.

Can you please upload both, ACAD.PAT as well as ACADISO.PAT so we can see the differences to our files that work well.

Yes, you should be careful with that ... but if that file has defects and you keep on working with that defect patterns, things get worse!

Well... because i'm working from a shared server, i don't have access to those files.

[Alfred.NESWADBA]

Hi,

>> i don't have access to those files.

Then AutoCAD would not have access to these files too ... something is wrong here.

It works with a Citrix client program

[Alfred.NESWADBA]

Hi,

then you need to ask the admin to replace the ACAD.PAT and ACADISO.PAT with the original one, someone has edited the defaults which should not happen at all.

You might create your own PAT file, but then you need to add a path to the AutoCAD support paths (so AutoCAD can find your PAT file) ... I guess you are not allowed to do that too, correct?

If found a way to get access to the acad.pad file, all the pattern-difinitions are same compared to the definitions in previous answers. Is there a way to adjust the spacing between pattern objects?

[Alfred.NESWADBA]

Hi,

>> If found a way to get access to the acad.pad file

Than upload the file here so we can look into it and see if the pattern "GRASS" is incorrect or ok.

>> Is there a way to adjust the spacing between pattern objects?

For a hatch you can only adjust the scaling from AutoCAD.

To edit the pattern itself you need to go through all lines in the hatch pattern definition as this is not just "space between pattern objects" (as every single line in the hatch pattern has to be defined by separately).
