Variation in lineweights of family surface patterns

[Anonymous]

Thanks to forums like this I have found so many answers to Revit issues I have had. I really appreciate all of the help people are willing to provide using this program. This is the first time I have had to post anything, as I have not been able to find a resolution to an issue I am having with some family surface lineweights.

I am working on a model that has a lot of structural timber families. These timbers have a material assigned to them which has a wood grain model pattern assigned. I have made it grey for visualization purposes.

Most of the timbers appear in drawing views and 3D views with a "thin" grain pattern, but a minority have a "thick" grain pattern. Oddly these are the exact same families....I open the family files up and they are the same name and have all of the same attributes. I did not originally create this model so maybe there is an issue with how it was built.

My understanding from searching for an answer to this is that there is no way to control the lineweight thickness of a family, at least directly. I have noticed that when I copy the thicker grain pattern timbers the copied version is thin grained. I can go thru and copy these all in place and then delete the ones I don't want but it is a bit of pain as there are a lot and they will need to be retagged. Also, I feel like I could do this and then it could reappear as thick again or something.

I already had an issue with this model which I was able to do a  workaround on which was that I had grids turned off in a view template but they were still showing in the views that the view template was applied to. Every time I closed and opened the model they would be there. I tried everything including auditing the model and eventually just turned them off manually!

Below are images of the variation in lineweights that I am seeing, any help would be greatly appreciated.

Are you sure they aren't coming from a Filled Region?

thank you for the reply. How do I get to that?

When I go to the instance or type properties for the timber I do not see a graphics option with fill and lineweight setting. I do not see it when I click to edit the family. I should have mentioned this is Revit 2018...is that feature available in 2018?

How do I edit system family: filled regions...I do not see it in the project browser. Just when I thought I was started ti get the hang of this program!

Never mind the Fill Pattern.  Post the file.

The link to the model is below. I have noticed that I can copy the beam with the thicker lineweight over "x" dimension and it will appear with thin lines. However if i copy and paste in place it has thick lines. I also tried copying the entire model into a new file and then all of the beams appeared with thick lines....

Something weird is also happening with the view templates and or filters. Not sure if this is related....

There is a lot of equipment modeled that I changed to be a casework family so it can be cut in section. I set up a filter so that in the framing plans the equipment is shown as a light dashed line (instead of a blue hatch that it is displayed as elsewhere). This had been working without issues.

I just got the file back from a consultant who was modeling more of this and now when I open the file the blue hatch is appearing in most of the framing plans instead of the light dashed lines that are applied thru the filter. When I take a look at the filter thru the view template visiblility is checked. If I uncheck visibility and exit the dialog box the equipment disappears...when I open it back up check visibility and then close the dialog box the light dashed lines appear.

However when I save, sync with central and reopen the file the equipment goes back to be displayed as a blue hatch!

Oddly the first floor framing has always shown the equipment correctly, the second floor was showing it wrong at first but it is now showing it correctly (even when closed and opened). The attic and roof framing has never worked after a reopen. All these plans have the same view template applied.

As I mentioned in my first post this was happening with grids....I had been hiding them thru annotation overrides in a view template but they kept appearing after a save and reopen.

I can't figure it out. Why don't open a support case through your Autodesk Account Portal and submit to them to troubleshoot.  If you do, can you report back to us what they say?   I'd love to know.  

FWIW: Revit material hatching patterns are displayed and printed using the Revit line-weight number 1, except Ceiling surface patterns which use line weight 2. This number is then converted to a line thickness according to the scale of the view on a Line Weight matrix chart accessed from Additional Settings on the Manage tab.  

Here's an example:

Not sure what causing it but you can cut and paste the affected members in place.

I kind of like it. I'd like to know how to replicate it.  

Did you check out the swatch?  Very interesting.  

[ToanDN]

Also, simply duplicate Type will fix it.

...more weirdness with this hatch pattern (see view scales):

What do you think @Pattycake_Kyle?

@barthbradley Also super curious on my end as well.

@Anonymous do you have the original source/pat file for your wood_5.pat i could dig into? I don't think this is a PAT file issue (and as everyone else is thinking, probably some weird thing with revit). I loaded in other various model patterns and it was having no effect. Could always check to see if it has some weird errors or something though.

@Anonymous Check to see if this solves your problem... Edit the family. Go into the material. For the texture alignment, click it around, like 5 arrow up, 5 arrow right, etc... Make it stop a place where it wasn't. Then re-load back into the project. This solved it for me. 🤗  (if it doesn't solve your problem, maybe try one or two more alignment positions, maybe i just got lucky).

My theory is that it may have to do with the PAT alignment for 2 reasons. First, since various PAT files were running into this its probably not the PAT file. Secondly, I noticed taking some of the beams and adjusting size/extensions to the ends was triggering it, which makes me feel like it was an alignment/origin issue. This seemed to fix it for me, but i tested in R2019.

Other than that @ToanDN solutions seemed to work for me pretty globally (new type) and open up the Autodesk ticket. 😖😖😖😖😖😖😖
