Visibility of filled region nested in lighting fixture family on a pitched roof

[tbagul1]

Hello,

I am working on a project where the emergency light fixtures have a gray hatch in it. I have edited a manufacturer's family and nested a solid grey filled region detail item family into it for the emergency light fixture. The light fixture family is face mounted and I need to mount it directly on bottom side of a roof which has a pitch to it.

I understand that the Symbolic Elements Visibility of a detail item family notes that it will be visible only when the family is placed parallel to the creation view.

I want to ask if there is any other way for the hatch region to show up if the light fixtures are mounted at a pitch to the creation view?

Any help is appreciated!

Edit family, tick the "Maintain Annotation Orientation" box

@iainsavage - This should technically work but for some reason it did not for me. Attached is the family with that option checked.

Not sure what is going wrong. Any idea?

I'm by no means an expert on this, I was relying on the help topics for info.

I found this post and it looks like you maybe need to use a nested generic annotation rather than a region in the family.

@HVAC-Novice could maybe clarify.

In my experience, if ever you mount something on an angle the symbol will not show up since it is 2D element. The only way we have been able to get around this is by not using face hosted elements. Rather we use level hosted elements. The symbol will therefore alway be able to be perpendicular to the view and the nested model element has the ability to rotate/spin about its origin point. Provided you build your family with that ability in mind. Face hosted families do have their benefits and ease of use but if the drawing symbol fails to look appropriate you choose work arounds that allow you to do what you need them to do. In my case we rotate the model portion of the family only after placed rather than the entire family, thus allowing the annotation to remain visible in the view.

Since 2022 the "Maintain Annotation Orientation" parameter was added to address the issue of face hosted elements on slopes, but it seems that it maybe only works with certain types of annotation objects and filled regions aren't included? @tbagul1 did you try making a generic annotation family containing the region - I tried it and it seems to work:-

Does the filled region mean to present a graphic symbol or the actual shape of the fixture?

Never mind, I see the family.  Since the filled region is the actual size of the fixture, why don't you show the actual 3d element and use a material with solid grey surface pattern for the box?

That is for Annotations, not Detail Items.

Closing this topic for now. I have used the solution provided by @ToanDN. I unchecked the visibility of all of the elements (except the family extrusion) of the family in Detail Level: Medium and changed the color of the family extrusion to the filled regions color and it works now.

Not sure it this is the correct way to do it but it solved my issue.

Thanks all for the help! @ToanDN @iainsavage @mikewp90
