Please Help: Clipping plane hatches, section styles referenced blocks

Serengeti (Rhino WIP) Drafting & Illustration

I found Simon Vorhammer had this same issue, under the title shown below related to Rh8. I have this issue with Rh8 also, and I checkedRh9WIP by opening the two files in Rh9 WIP to see if it resolved there. I find the same issues in Rh9WIP. Maybe I’m missing something, or maybe it’s a specific hatch .pat file. I can’t seem to figure out what’s causing it.

ref: BUG: Clipping plane hatches and section styles from worksessions by Simon Vorhammer

Basically I have a file of, say a door, with section styles & hatches defined by layer. I import the hatch(es) from a file modified from an acad.pat file I have used for many years. This door file is then referenced into another file to make layouts and working drawings using clipping sections. What happens is that I work in the working drawings file and it looks great with hatches on all of the cut parts, all is great. Then I close the reference file, close the working drawings file, saving each as I close it. Next time I open the working drawings file, the hatches are all mixed up. Then I check the referenced file, and they are not saved there either. Incorrect hatches are showing for section styles as I had assigned them. I’m thinking it may have something to do with this wood end grain hatch pattern that is like really long . . . 24kb just for the .pat file? is there a limit on size of the .pat file? I change the patterns back in the referenced file, save, and it will not update in the drawings file. I do suspect the hatch pattern file that is attached because it is very long. but It will display fine in the local file, and I’ve used it for many years. ?? Any help will be greatly appreciated. Thanks again in advance.

This one i can repeat. Thanks for reporting RH-90016 Section Style losing pattern in worksession file

3

Awesome! At least I know it’s not just me, or my system. Thank you Japhy! Did you find it had anything to do with the HWEND long hatch pattern?

4

That may indeed have something to do with it. A ‘normal’ pattern works as expected. We’ll see what the devs come up with!

5

I’m not positive, but I don’t remember this issue coming up before the last update that came out (Rh8) a few days ago.

I am able to get it to read correctly at least in one session by changing the block reference to “Embedded and Linked”. It makes a ton of active layers which I like to avoid, but it’s working. I’ll have to save, close, & open agai & re-post to see if the changes stick. Also what I’ve found is that the hatch pattern is off by one, in other words the hatch pattern shown was the next one down the selection list when choosing the pattern in section style from the layer container. It seems the list is shifted down one or something. I’ll report back about re-opening.

7

I saved and closed both files & the hatch patterns show correct with clipping sections, so it seems the workaround of using reference setting of “Embedded and Linked” seems to be working but nested blocks need to also be set to “embedded and linked”. The shifted list did not always hold true, so I’m not sure what it could be . . .
