Detail Line based Component (and filled region) shows Gray except with Thin Lines or zoomed at a particular distance

[christopherrYA37U]

I am trying to use a simple line based family with a locked filled region. For some reason in the file we use for adding items for making a template the pattern shows as gray except with thin lines on or at a certain zoomed out distance. Any ideas?

I can copy the family into the Revit standard template and there is no issue whatsoever with it displaying correctly only in this file.

Using Revit 2020 and upgrading the file to 2022 does it does the same thing.

I have checked object styles, line weights for the filled region between  projects, ever graphic setting I could find and no clue why it does this.

Edit:  maybe share you project file with that family here (just need a blank view where that family shows not per your liking).

Revit omits model patterns on screen if they are too dense.

It is a drafting pattern not a model pattern which is why I am so confused.

That is the expected behavior of a drafting pattern. 3mm spaced lines at a scale 1:100 would display 10 lines in a filled region, that same pattern with the same spacing/scale would populate and multiply to fill the same region with 100 lines if the scale is 1:10 ...it would still print @ 3mm spacing but on screen it would look gray till you zoom in or activate thin lines

If that is not what you are expecting, maybe you need to use several nested filled regions with various spacing/scales of the same pattern or maybe use a Model pattern in that detail item

Drafting Pattern?  Sounds like View Scale is the culprit.  

[christopherrYA37U]

If i go file new project , architectural template (stock revit one) it works at all scales no issues. I load it into this one and it goes gray at all scales. My expectation is that is works like it does in a blank project because it works in that one no issue.

Compared to the behavior shown in the GIF in my previous reply (Drafting vs Model pattern behavior), is it the same what you see at your end with your detail item family or are you expecting anything different?

Can you upload the Detail Item placed in a project? it is hard to visualize what you are seeing and what you are expecting to see

[christopherrYA37U]

I dropped some screen shots below.

Expected is a blank new project file. It shows up NO Thin Line setting at all Scales.

Whats happening shows the gray that happens at all scales

What happens at all scales 3IN equal 1 foot shows that the scale does nothing different to what it shows.

The behavior is perfectly normal and as expected...

Match the Length and width of the filled regions in the two views where the scale is 1/2" = 1' (ie: Whats Happening.png and Expected.png) ...then you can compare apple to apple.

Drafting Pattern at 3"=1'-0"?  Those results make perfect sense to me.

View Scale not pattern scale

@christopherrYA37U 

That is odd... it is not how its behaving at my end...are you sure the pattern scales are the same? that is a custom pattern

Can you upload the .pat?

Those are not the same: Fine vs Medium, Coordination vs Architecture.  Not saying that they are the issue but you should always compare the same settings.  If matching these settings doesn't fix it, look at the view filters see if any overrides.

Here is what I think you are experiencing (different import scales of a custom drafting pattern) and how it may be fixed

1. transfer Project standards from the project where you say it behaves as expected 
2. Pick Fill Patterns
3. Overwrite the fill pattern

[christopherrYA37U · Accepted solution]

@Anonymous@RDAOUI narrowed it down to the fill pattern being the issue. It was a custom fill pattern but I did not have the original .pat file so I could not check what was wrong with the .pat file.

Similar to what @Anonymous recommended I tried to transfer the fill pattern over but nothing changed so I figured the pattern file was screwed up some how. So I needed a work around and this is what I came up with and ultimately fixed the issue.

Step 1 - Create a filled region with the pattern I wanted from the family file.
Step 2 - Export the view to a dwg
Step 3 - Open the DWG in CAD
Step 4 - Drag GETPAT into the DWG
(If you do not know GETPAT, it's the best way to get hatches from autocad out to .pat files I have found. You drag GETPAT into your autocad file. Type GETPAT enter, Select Hatch and then it will export/save the hatch as a .pat file. )

Step 4 - Selected the hatch and got the .PAT file.

Step 5- Open the family file again

Step 6 - Tried to create a custom fill pattern and select the .pat file but it wound up shifting lines for some reason so instead I used PYREVIT  make pattern → batch import to load the .pat file in and it popped in correctly.

Step 7- Drew a filled region with the new pattern

Step 8 - Adjusted the pattern scale to x3 (not sure why the scale changed from 1.0 in revit and YMMV but x3 worked for me)

Step 9 - Matched properties from the filled region I drew to the orginal and purged the family file.

Step 10 - Loaded the family in and it works on every scale

Strange that Transfer Project Standards > Fill patterns did not work.  Did you choose overwrite

Anyhow, if you are already using pyRevit then why can't you Export PAT file from the good existing pattern and recreate the pattern from that PAT file in the troubled model?
