Archicad 29: poly2_b{5} outline missing (covered by fill?) despite separate calls

[til0byte]

Hi everyone,

I’m working on a 2D furniture object in Archicad 29 that changes its representation based on a custom Model View Option (MVO).

The Problem: The fills render correctly (Solid, Dashed, Colored), but the outlines (contours) are invisible in regular view. However, when I select the object in the floor plan, the dashed/solid outlines appear as part of the selection highlight. It seems like the fill is overlapping the outline, even though they are called separately.

I am using the poly2_b{5} command and I’ve already tried adding explicit pen resets before each call.

! ---- Standard Initialization ----
pen gs_cont_pen
fill gs_fill_type

! ---- Constants ----
DISPLAY_HIDDEN  = 1
DISPLAY_SOLID   = 2
DISPLAY_DASHED  = 3
DISPLAY_COLORED = 4

! ---- Read MVO Settings ----
_mode = 2
_ok = LIBRARYGLOBAL("ModelViewSettings", "iDisplayMode", _mode)

! Mode 1 = Hidden: draw nothing
IF _mode = DISPLAY_HIDDEN THEN GOTO 999

! ---- Determine Pen Color ----
_pen = 19
IF _mode = DISPLAY_COLORED THEN
    _pen = 85
    IF iResponsibility = 2 THEN _pen = 104
    IF iResponsibility = 3 THEN _pen = 114
ENDIF

! ---- Set Line Style ----
IF _mode = DISPLAY_DASHED THEN
    set line_type 25
ELSE
    set line_type 1
ENDIF

! ---- Main Body ----
IF _mode <> DISPLAY_DASHED THEN
    ! (1) Fill (Solid/Colored only)
    fill fillAttribute_1

            A-_vx, B-_vy, 1,
            _vx,   B-_vy, 1,
            _vx,   _vy,   1
    ENDIF
    ! (2) Contour

        _vx,   B-_vy, 1,
        _vx,   _vy,   1
ENDIF

999:
end

Has anyone encountered this behavior with poly2_b{5}? Is there a specific draw order or distortion_flag I might be missing to ensure the contour stays on top?

Thanks in advance!

Have you tried to let the object create the script. Here the outer lines are visible. Please compare it with your script. (AC 29 , MAC OS)

pen         24

Any particular reason you are not using inline conditionals to flip the bits?

In my opinion keeping it DRY is a better style.

So I'd do it like this:

pen mypen
fill myfill
has_outline = not(_mode = display_hidden)
has_fill = (_mode = display_solid) | (_mode = display_colored)

poly_2b 4, has_outline+2*has_fill+4, pen_fg, pen_bg,
    0, 0, 1,
    ... etc.

Not sure what you'd need version {5} for in your code, but there it's the same.
