Window opening dash line goes missing?

[noconnorG728Y]

Hello everyone again.

I have a unit model and block model that has window dash opening line shown up on elevations but when I linked the block model into the site model. Some of the lines seems to disappear per image. Any idea why? All elevations templates are the same.

TIA

It may be that the face on which lines are disappearing is oblique to the elevation. See pasted image, the blue and red circles both show the same manufacturer's operable window family. However, the section of building in red is oblique to the elevation view so those lines dissapear. For the CD set I just manually drew them in there as detail lines but your other option is to make their model lines instead in the window family, and they will show up in 3D then also

Symbolic lines only show when they are parallel to the view plane.  You can convert the swings to model lines then they will always show regardless of the window orientation.
