Window casing, frame and sash not showing 100% in section view

[artktecture]

AC24, using the W1 Casement 24 object in a complex profile wall (or any wall for that matter), I can't get all of the lines for the interior and exterior casing or the window frame/sash to display in section view.

Pic#1 is the top of the window

Pic#2 shows the missing lines I want displayed (in red)

Pic#3 after I add a complex profile window header, the thick red line also does not display

I've tried every combination of settings I can think of. Is this a building material priority, a fill, a junction order issue, or something else? This has bugged me for years and I really want to solve this. 

Thanks in advance

Make sure the Building Materials they are using are different, otherwise the fills of the same Building Materials will be merged in section.

Where do I change the building material in the W1 Casement 24 object? The only settings I can find are for the surfaces...

I've never seen this behavior, and just tried to reproduce it with an out of the box composite wall and W1 Casement 24 and changing all kinds of settings/materials and the lines always show for me.

Could you select just the wall used in your screenshots and save it as a module/MOD and post that here?  MOD files don't include attributes, so we might not be able to see what's going on from that, but it's a tiny file so an easy first step to take a look.

Select the wall, then

File > External Content > Save Selection as Module...

Open the MOD on your computer, cut a section through it, and verify that the issue is shown, then upload the MOD file here.

If this platform doesn't let you upload MOD files... then just zip it and upload that.

Had to zip the file, thanks for looking into this.

So, I found two problems going on.  One is with the settings for your section marker; the other is the fill settings for the window object.

I couldn't see exactly what you see, since I used the USA default template where the pen colors don't match what you have in your screenshot, but I placed an out-of-the-box W1 Casement 24 in your wall and duplicated your section and saw a simlar issue - the joint lines were not showing.  This setting in your Section settings was the culprit for that:

 

Changing Fill Cut Surfaces with... to "Cut Fills - as in Settings" showed all joint lines.  With "Own colors", since all pieces of casework are the same color, they merge.

Next I changed that Section setting  cutting through your W1 Casement 24, where a variety of parameters had been changed... and I still didn't see the joint lines. Your casing, frame, and sill cut fills were all the same - so they merged.  By changing to unique fills, the joint lines show.

Thanks, it was the cut fills. I already had the section set to "Cut Fills - as in settings".

Do you know if there is a way to turn off the "merging" of identical fills rather than changing to unique fills?
