What does the "Draw in Foreground" for Symbolic Lines do?

Inside a family, you can check or uncheck the Draw in Foreground for Symbolic Lines (not model lines).

 

But what does it do?

I tried to find any documentation on it, with no luck.

 

It is checked by default, and I had a case where I benefited from unchecking it.

 

Here is with checked: I got a family hosted on a sloping floor

and here is with Draw in Foreground unchecked: the part that previously got cut away by the sloped floor is now visible.

Please note that, for this to work, I had to place the red lines on another reference plane than the level plane, plus I had to raise it above the level-level so that it wouldn't get buried under the sloping floor.

 

For reference; Here is an example where the slope is extremely steep, and as you see the red circle got buried.

To sum it up: Draw in Foreground for Symbolic Lines, what does it do?

Here's a help article with examples:

 

About Masking Regions in Model Families

Hope this helps,

Hi @lucdoucet_msdl 

 

I have seen this article, and it wasn't relevant to my case. I read it again just to be sure.

 

Please take a look at the provided revit file (2021) and you can see for yourself.

The behaviour is the opposite; if Draw in Foreground is off, then it works, not the other way around.

Also, I am checking this checkbox for Symbolic lines. The article you posted spoke only of Masking Regions.

I treat Foreground as hybrid 2D symbolic/model lines and Background as hybrid symbolic/annotation lines.  They could have used some better wording instead of Foreground and Background though.

Aha.. So if I understand you correctly, no matter the linetype (symbolic or model), if I have Foreground checked either linetype behaves like model lines, ie hidden if physically hidden, and if Foreground is unchecked either linetype behave like symbolic/annotation lines and hence visible?

 

If yes to above, then at least the wording should be the other way around, no?

 

(edit: corrected Background to Foreground)

Yes.

Perhaps.
