Hiding vertical lines in holes in Prisms

[James Murray]

I would call this a bug. It is not possible to hide the vertical lines in a curved hole (with either 13 or 79), unless the enclosing polygon uses 13 or 79 as its last status, which results in hiding a line that should be shown.

hA = A/2

PRISM_ 7, 1,
    0, 0, 15,
    A, 0, 15,
    A, B, 15,
    0, B, 79,
    0, 0, -1,

    hA, hA, 900,
    hA/2, 360, 4013

If you change the last 79 to 15, the lines within the hole will show.

OK, here’s the code since it’s not showing:

hA = A/2

PRISM_ 7, 1,
0, 0, 15,
A, 0, 15,
A, B, 15,
0, B, 79,
0, 0, -1,

hA, hA, 900,
hA/2, 360, 4013

James:

This will work:

hA = A/2

PRISM_ 8, 1,
0, 0, 15,
A, 0, 15,
A, B, 15,
0, B, 15,
0, 0, 79,
A, 0, -1,

hA, hA, 900,
hA/2, 360, 4013

Maybe one of the Graphisoft folks can chime in if there is a better solution, or if this has an inherent problem.

That’s… interesting? I’d rather they just fixed it. Thanks for looking.

Is it just a MAC thing?
I see no difference for either script.

Look at the other side of the Prism.

Hi James,

yes, this is a bug, we’ve discovered it just recently, there will be a solution in ArchiCAD21 to fix this.
Use TUBE instead of PRISM until then:

TUBE 7, 4, 1 + 2 + 16 + 32,

    0, 0, 0,
    A, 0, 0,
    A, B, 0,
    0, B, 0,
    0, 0, -1,

    hA, hA, 900,
    hA/2, 360, 4001,

    0, 0, -1, 0,
    0, 0,  0, 0,
    0, 0,  1, 0,
    0, 0,  2, 0

Ahh I see.
Sorry I was looking for the lines in the hole.
