Filled Region Obscured by Linked Model

[Anonymous]

There is a lot on the topic of filled regions, but I have something happening that doesn't seem to be covered.

I have a filled region set to transparent. I am annotating in a host model and the building is linked in. For some reason the boundary lines only appear over certain portions of my linked file. As you can see from the screen shot I have attempted to illustrate the issue. On the left side the filled region is clear of the linked file and shows correctly, and on the right side it also appears correctly over the linked file. In the middle for the boundary lines are being obscured. This screen shot is with just the linked file and the filled region isolated, so there is nothing else to obscure the filled region.

I have a large project with many linked files and this is the only one that has this issue. It is not a view specific issue since I can drag the same filled region over the other linked files without any issue. Any ideas on why this is happening? Thanks in advance

If the link is set to by Linked view in V/G then its filled regions can cover yours?  Set the link to underlay in V/G see if it helps.

It may be because of your visual style. Try to shift between wireframe and hidden line visual styles. This will usually solve my problem. (if it doesn't interfere with anything else.)

Try to send the region to back or bring to front will help sometimes.

Interesting. This does solve this issue, but creates other issues (such as not being able to tag elements). There are no filled regions in the linked model, so it can't be that. It is strange because there are 12 linked models and none of them are set to underlay and none of them have that problem, so it's isolated to this one linked model.

If it was a VG issue, I don't think it would show up at all. I used a different plan that had a different linked model as a view template and still the same result, so it's not a VG issue, however wireframe does make it visible, but that does not work for how I need my plan to be viewed.

If you can drag the filled region over other linked files without any issue, then why are you attributing the issue to the filled region. Could there be another element blocking the view; like a masking region perhaps?

To eliminate that possibility, I temporarily isolated only the link and the filled region and it didn't make a difference. I can also make any other annotation without any issues.

- Is the view Hidden or Wireframe?  It should be Hidden.

- Are there any DWGs in the link?  If so, turn them off.

[barthbradley]

Okay, now try isolating all of the Links in the view, as well as that one Filled Region, and then drag the Filled Region over another Link. Issue or no issue?

...Just to confirm: You stated that this is not view related because you dragged the Filled Region over other Links in the (same) view and there was no issue. Is this correct? You have other Links in the view?

- It is hidden line

-All DWGs are off.

 Correct. I have other links in the view. I dragged one filled region over all the links and this is the only one that has the issue. I also did as you suggested. I isolated all the links and only the one filled region and it yielded the same result.

Don't need to go to the gym now; I'm getting a workout reading this thread. Burning calories as we speak. Ha! 

...I see where @ToanDN is going. Keep us informed.

I thought you were onto something, but unfortunately it did not make a difference. Something did make a difference, but unfortunately it's not helpful in this situation - when I make the filled region opaque it fixes the visibility issue.

[Anonymous · Accepted solution]

So, if anyone else is having this problem. I found the cause, but not really an answer on why it is happening. So, you can fix it, but it's strange.

It was the material of the roof. I changed the material back to "by category" and the filled region is now visible.

That's probably not ideal in some instances where you need a different material, but at least you know that sometimes a material will for some reason make a filled region not visible.

I hope that helps someone else not pull their hair out.

[barthbradley]

Yes, that doesn't make a bit of sense. What's the "by category" material, out of curiosity? 

[Anonymous]

No material is set. A colleague managed to find this from Autodesk:

https://knowledge.autodesk.com/support/revit-products/troubleshooting/caas/sfdcarticles/sfdcarticles...

Seems like a bug since they say you "may find..."

[barthbradley]

Good information. Thank you, @Anonymous. I bookmarked the link. I'd earmark here as the solution as well.  Give yourself 2 solution credits!

I would consider this a dumb Revit glitch. This was my workaround.

Other workarounds attempted before arriving at this solution, in case anyone wants to have a go:

• flipping between Bring to back and Bring to front
• swapping from wire frame to hidden line
• applying an override in the view template on category "Detail Items"
• changing the color of the filled region
• switching from masking to not masking (it should be on NOT masking)
• recreating the hatch in case it was corrupted
• switching to another hatch pattern
• making it a group
