hatch patterns are always visualized as solid

[ali.bernardeschi]

i don't know why but patterns don't work on the model, everytime i choose one it visualizes on the model as solid. I tried many ways to solve the problem, changing the values of hpmaxlines, restarting the programme and even downloading it on another device, but no changes happened. I don't know how to do pls help.

(i have autocad 2023 version)

Hi,

How about changing and modifying the Scale value ?

[ali.bernardeschi]

first of all, thank you for the answer.

I tried many different values (from 0.1 to 10000) but the problem still persists.

[imadHabash]

Would you please attache here a CAD dwg sample with that hatch , for testing ? 

[ali.bernardeschi]

sure here it is. thank you.

(i don't know if you can visualize the hatch, i tried to save it but it doesn't appear to me as i re open the file)

No, we can't -- there are no Hatch patterns in the drawing.  What pattern are you trying to use, and in what area(s)?  I am able to call for a non-Solid pattern and have it preview correctly in closed areas.

There was an error so I used the RECOVER command to open the file

Then your UCS is set at a strange orientation so I set that to WORLD

Hatch successful using scale factor of .05 for ANGLE pattern

Thanks for your CAD dwg ..

You have a problem with your UCS icon and general orientation for your drawing .. Your issue will resolved if :

• Type in command line UCS command then type W from World option .
• Type PLAN command then double enter .

Try now to hatch , any changes ?

I don't think that can be it.  I simply opened the drawing, and did this Hatch in it [the yellow], without doing anything at all about the Coordinate System or Plan view.  After picking a non-Solid pattern in the Hatch ribbon [in this case ANSI32, and at a small scale factor], it previewed correctly when I floated my cursor in that area.

Thanks for the DWG file @ali.bernardeschi 

1) your file opens on a floor plan that is TOO FAR away from 0,0,0

2) your DWG file is in mm units: are you really drawing and dimensioning rooms in millimeters, then fudging the dimensions to show meters?

There are many issues in your file that need addressing.

Thank you for the answer, I know about the issues but it's my first time using autocad for an uni exam so I'm still learning how it works. I solved by copying all elements into another dwg file to start again and now all hatch patterns work!
