cut pattern on linked files using line weight of object styles cut setting of linked file

[hj.rozendomSTYFU]

While working with linked files in a project I wanted to override the cut pattern of an element in the link to comply with our industry standards. I managed to do this using a filter. Somehow however the lineweight of the hatch was way thicker then for all the other (non linked) elements in the view using the same cut pattern.

I found out that the line weight of the hatch correlated with the line weight of the object cut style in the linked file, changing this setting in the linked file and reloading the link would change the lineweight on the hatch (but somehow not the cut lines of the object itself).

Is this normal behavior? Or am I doing something wrong? Or could this be considered a bug?

Maybe it would be easier to understand what is going on if you attach the a model or some images?

Sounds like the "hatch" linework is coming from a Filled Region and not from a Cut Pattern that would be defined under the Graphics tab of the Material.  Cut Patterns' Line Weight is Pen #1, whereas the Line Weight of a Filled Region is defined under its Type Properties.

I used a filter and used the Cut override pattern, so no, it is not coming from a filled region. I'v added a few screenshots to clarify

If the element in the linked file is a loadable family like a structural framing element for instance, check/edit the family and check if it has a nested detail item...that would be where it is getting the line weight from.

as mentioned before, I override the cut pattern with a filter, normally it would not have the cut pattern at all. And I can actually change the line weight of the cut pattern by changing the object style setting in the linked file. So it is not a nested detail item.

Both statements cannot be true.

1. Being able to apply an override by filter does not mean that there is no detail item nested into the family...(See GIF 1)
2. the cut pattern line weight is neither affected by the Cut Pattern settings in object styles nor by the overrides in Visibility Graphics (See GIF 2)

What do you see when you 1) remove all filters and overrides, 2) Set your linked file Display to Host and 3) Change View Display settings to coarse / medium and Fine successively...

GIF 2: Line Weight override does not affect cut pattern line weight

as mentioned, it does not have a nested detail item. attached the view without overrides set to coarse, medium and fine. All show the foundation in the linked file as blank, because it does not have a cut pattern, nor a nested filled region. The only cut pattern applied is that of the filter override.

What I forgot to mention is that the linked file is an ifc (that can be openend seperate in revit by opening the automaticly generated revit version of the ifc).

Also I can change the line weight of the cut pattern by changing the object style of that item in the linked file.

Good that you mentioned its an IFC ... I didn't see that in the OP and in my previous reply I did sate if it is a loadable component :)... IFC generated elements are direct shapes and any cut pattern you apply there (by any means of override) will be treated as a CUT. Revit components with Material Fill pattern follow different rules

Do the following:

1. Open the .ifc.rvt file
2. Kill the Filter override 
3. Go to Object styles set cut line weight 1
4. Place a section view
5. Oprn and go to Visibility graphics
6. Override Cut Lines to 7 or 8 (up to u)
7. Override Pattern (Pattern will follow the Object Style cut weight - However, Color will follow the Override in Visibility Graphics)
8. Save
9. Open Host model
10. Reload
11. Go to VG and set Link display by Link then for view choose the section view you created in step 4

Result should be as below GIF

I see, so its the fact that it is an IFC that makes it behave different then usual. Weird and unexpected behavior, but at least now I know why it is doing this. Thanks!

Its not because it is an IFC...but because the elements you see are direct shapes and not Revit native components and it is a normal behavior of direct shapes you generate in Dynamo or you find lots of Revit families created using elements modeled in different software...lots of these on bimobjects
