Can't override surface pattern with a model pattern?

[patricks]

I have some ceilings that I need to apply a different model pattern in one specific view. However I noticed that the Override Element In View function has the Model pattern button grayed out when you try to pick a surface pattern. Why would it do this? Has it always done this ever since the object override functions were introduced in RAC 2008?

How can I get a different surface pattern on a ceiling in only 1 view? Painting the surface is out of the question because that affects all views. Linework also does not work on model pattern lines.

Hi! Yes you can do this. The trick is to select the ceiling object, not the model pattern lines. Put your mouse over the edge of the ceiling and tap your tab key until the ceiling object is highlighted. Select it and then right click. You will be able to change the surface pattern at that point.
Best regards,

Negative.

Select the actual ceiling > right-click > Override element in view > Surface Patterns > only drafting patterns are available.

It appears this is the case for all model elements.

I can't believe this. I'm actually having to draw lines over my ceiling grids in a couple of views just to make it look correct.

I just ran into this same issue. Did you find a decent workaround?

Nope. I just had to do the lines over the dashed ceiling grid pattern.

Revit Support tried to suggest using filters, but that is just as useless as the element overrides. In fact, no model element of any type can have its surface pattern overridden with another model pattern. Drafting patterns are the ONLY pattern overrides available system-wide.

There may be a way to make it work using overlapping instances of the same ceilings, and some tricky manipulation of phase created/demolished of each ceiling (some may end up temporary in the same phase), but I haven't delved into it that much.

I ended up doing transparent filled regions over my ceiling grid as a work around. I tried to do a graphic filter, but ran into the same as what you described... not model patterns for overrides. I don't know why Revit has that limitation.

Thanks for your help.

[patricks]

Actually that sounds like a better idea than lines. I only had a few ceilings to deal with, maybe 6-8 total, and 6-8 filled regions with a model pattern would have been alot better than nearly 100 lines per view!

This is really annoying. We've run into this issue where we have existing elements with their surface patterns overridden but we need to apply new tiles to an existing wall. The only ways we can do this are via filled region or a drafting fill pattern with the scale worked out. Seems a pretty weird decision to take on the dev's part.

Any fix for this yet?

Or is there an easy way to convert a model hatch pattern to a drafting pattern?

[dbaldacchino]

I can understand why you want to override the surface pattern, but what's so important to use a model pattern? Think about it....model patterns are supposed to represent actual model geometry but in "wireframe" format so to speak. So if you override a model pattern, in essence you're changing the model. I believe that's why you can only use a drafting pattern. This way it's only a view-specific override. If you want to use a fill that is only available as a model pattern, you'll have to convert it to a drafting pattern. If it's available in a pat file, then you can do that easily.

[patricks]

We wouldn't have this problem if we had some kind of model pattern editor that would allow the use of actual line patterns that are defined in the project, and subsequently, be able to override those line patterns on a per-view basis (or override the pattern of lines in patterns using phase graphic overrides).

Hmmm, seems you can split the face of the ceiling, paint a new material onto it, and that material's surface pattern is adjustable as a model pattern.

But that's still a model pattern that shows in all views.

My original question related to overriding the pattern with a model pattern in only a single view, using the element override in that view.

[bregnier]

I agree with patrick here. To me model patterns and drafting patterns really don't have the same set of distinctions as model and drafting lines. Drafting patterns applied to a material still show up in all views, after all. To me the difference is really only in the scale and orientation of the pattern. Where i get frustrated with this is 3d views, as drafting patterns will rotate and shift on you and won't follow the geometry.

My only guess is there is a fundamental difference in the way that Revit treats these patterns in the database, which makes it difficult to override one but not the other...?

[stuntmonkee]

I'm trying to do this through a view filter, still no go. Looks as if you can only override a surface pattern with a drafting pattern and not a model. Seems kinda silly, but what do you do.

... but what do you do.I just went through this myself recently and here's what I ended up doing.... :banghead:
