I have a Detail Family with a Filled Region: Fill Pattern=Diagonal Up (Drafting), Background=Opaque, Line Weight=1, Color=Black.

I have nested this Detail Family into a Generic Model Family. Filled Region displays correctly in the Generic Model Family: black Diagonal Up lines over an opaque background (=white; screen background color).

When I load this Generic Model/Detail Family into a Project, the Filled Region displays black Diagonal Up lines over a GRAY background. However, if I load the Detail Family directly into the Project, the Filled Region in that instance displays black Diagonal Up lines over an opaque background (=white; screen background color).

So, what am I missing? Why is a background color being applied and, where is it coming from?

While in the project, look in your materials and change the color for default.  Let us know if that works.

Tried this; can't locate a Material that's associated with it, or a Graphic Option. It totally replicable from scratch though.

 I create a Detail Family with a Filled Region: Cross-hatch of any kind with an opaque background. I load this Detail Family into a Generic Model Family and then load this Generic Model Family into a Project...Opaque Fill is GRAY.

I load the Detail Family directly into the same Project...Opaque Fill is White (Screen background color).

Two Family instances. Same Detail. Two different fill patterns.

EDIT: Same result on a different workstation. Apparently, this is normal behavior. Still, I wonder what is determining the fill color.

EDIT: WYSIWYG. It does print filled too.

I told you what material to change "Default"  - Try that!

You can repeat it and punctuate it all you like, WWHub, but your suggestion DOES NOT work.  I already told you this. There is NO Material associated with this fill pattern.  I get the exact same results if I create the two Families and the Project with no materials in any of them – zero, zip, nada.

A Filled Region’s opaque fill pattern is supposed to be the color of the screen background. However, if I load the Filled Region Detail Family into a Project as a nested Family within a Generic Model Family, the fill pattern is GRAY. But, if I load that same Filled Region Detail Family directly into the Project, the fill pattern is the color of the screen background.

Try it out for yourself. Follow these steps I posted on Revit Forum:

1. Create a new family using a Detail Family Template. In that Detail Family sketch a Filled Region and assign it any OOTB cross-hatch pattern. Set the Background to Opaque.

2. Create a new family using the Generic Model Template. Load the Detail Family created in#1 above, into this Generic Model Family (Plan Vew: Ref. Level View).

3. Create a new Project. Load the Generic Model Family with nested Detail created in #2, into this Project (Plan View: Level 1). The opaque fill is GRAY.

4. Load the Detail Family created in #1, into this Project (Plan View: Level 1). The opaque fill is White (or whatever the color your screen background).

If you notice, in my first post I only suggested that you change the default material setting and I asked you to report if it worked.  I did not know if it would or not.  So I followed your test.  Images:

1. Detail with opaque filled region
2. Detail loaded into Generic model with annotative line and 3D cube (Note region hides cube only.)
3. Generic placed in model with wall.  (Note, region is white and no longer hides cube or wall.)
4. View set to consistent color or shaded.  Both Cube and region are grey.
5. Default set changed to white - Generic set to model material.  (Note - cube is now white so default only affects the solid)

So the grey problem is only in a colored view not hidden line.

Thanks WWhub. So my take-away is that you weren't able to determine where the gray fill pattern is coming from either. So, basically, a nested filled region is useless to a point (yes, I understand it isn't an issue in Hidden mode). FYI: The other oddity I discovered, is that a nested Filled Region casts shadows.  Check it out: offset the Generic Model containing the nested Filled Region in Plan View and turn Shadows ON.

Anyhow, I appreciate your help. I'm going to submit this to Autodesk and see what they have to say.

Take care.

The fact that it is grey indicated to me that the program treated it like a solid and thus it would create a shadow.... That's why I thought it would be a default.   BTW - I changed all of the defaults to white but obviously this is a system level one that we don't see and can not change.

I don't like embedded details in model elements.   I have never seen them work well enough to mess with.   Better off to group.

So here is a strange one.  I took the previous detail element and added a masking region where the hatch was then added the transparent hatch family to the right of that, added a floor in the model and turned on shadows.   Now look at the image. This family is at 4'.   Cube has a shadow on the floor and the masking region.  Hatch only shows where there is no floor.

Now I modify the nested family back to an opaque one and .... what's this?  No grey tone in the hatch yet it seems to be opaque - masks the grey of the cube but the cube grey is gone where the masking region is.   The cube and the filled region casts a shadow but not the masking region.

NO PREDICTABLE RESULTS = DO NOT NEST!

Agreed. Let you know if Autodesk returns any useful information.
