In a few of our drawings I've found nice graphics I would like to reproduce in new drawings. It involves areas with hatching / Pattern, nothing magnificent but in a nice way to represent it.
I would like to indicate surfaces by shading, but without to hatche the whole surface.I want to fill only a small section and what I like here is that this hatched area has no dedicated frame. This is a great way to indicate surfaces.
How does this work?
I have played around a lot without success.
The only way, but without the same result was:- create a shape- hatch the shape (associative pattern not enabled)- delete the shape- group the hatch lines
However I would create a hatches surface as "Associative Region without frame".See the right shading on this picture and the attached sample file.

Hi Jan,
Thanks for this information.
I know there are some solutions to make the boundary invisible, by construction or by different level......
Since I have seen these graphics, the question arises how that was created?
Because I found this on MicroStation drawings, I guess that this must be possible ....
Thanks for any advice

The pattern/region tools that create associative regions always create an element that is "associated" with the original boundary element(s); If they change, it updates, if they are deleted, it displays itself as a failed association, etc.
I can think of one way to non-programmatically create an associative region element that is no longer associative, and that is by making a clipped copy. So create a larger pattern than needed with both the "Associative Pattern" and "Associative Region Boundary" enabled, then copy w/clip to extract the un-bounded portion you want from the center, and then just select and delete the un-clipped pattern and any other construction/boundary geometry you had to create.
I did verify that this approach works in SS3, not sure about earlier versions. HTH

NOTE: Your example originated as a DWG, the DWG importer will create this type of hatch.
in the hatch pattern tool choose the Flood ( looks like milk jug) and you can then have no association as long as there are closing boundary lines
don't have to be shapes you can even use a temporary line to stop the flood spilling out..
then delete the line and hatch ( or cross hatch ) stays like your picture .. personally I don't like this because it wont change if shape changes.. but if its what you want
it does work ..
As to patterning that's a different tool but works the same you can flood with a cell pattern or predefined patterns form library like the marshes symbol > \|/ or similar..
I like the earth patterning when using vertical sections or elevations below the Natural surface level....

Hi Lorys,
Yes this works, but as you write "without" association.
That means, I can delete the border lines, but the hatch then consists of a vast number of individual lines and not associated.
If you look on my sample file, you can see on the right hatch sample (without borde) that this lines are associated (grouped) and that you can modify the geometric form of it by snap & drag.
Point the mouse on this element and the info bar says also, it is a "associative region".
If I create as you wrote, without "associative" and then delete the border, I can group the hatch-lines but I can not modify the geometric form of it like the sample in my file.
Thanks
Regards
