Vent block windows

Anonymous — Wed, 24 May 2023 10:44:57 GMT

I need help to make a vent block window object similar to the picture shown
The window object I need is similar to the glass block wall window object included in the archicad library which lets you determine the unit size and the mortar joints. I think the programming to do this part could start with the glass block wall window object.
I did create the individual vent block but is a pain to copy it vertically and horizontally to construct the window.
The vent block is 8” w x 8”h x 6”Th. The hole is 4” x 4”
I don’t know GDL so any help is appreciated. Thanks in advance

To model this with all the mortar joints will get a little heavy on the polygons, but if there aren't great expanses of it that may not be a problem. (You can also do the mortar with a texture but the alignment can get a little tricky.)

For the fully detailed model, to make the blocks themselves use two nested FOR/NEXT loops:

FOR i = 1 TO blocks_across
FOR j = 1 TO blocks_up
Prism_ 10, dp,
    0, 0, 15,
    wd, 0, 15,
    wd, ht, 15,
    0, ht, 15,
    0, 0, -1,
    tk, tk, 15,
    wd-tk, tk, 15,
    wd-tk, ht-tk, 15,
    tk, ht-tk, 15,
    tk, tk, -1
addy ht + mortar_jt
NEXT j
addx wd + mortar_jt
NEXT i

You naturally need to initialize all the variables. In the example: wd, ht, dp = width, height, depth of block. For the mortar I would use a single Prism_ statement with holes defined by PUT statements in the above loop.

I know this is not a complete explanation (haven't time for that), but it's a start. Try fooling around with it and use the GDL Reference in the Help menu to see if you can figure out the rest.

When you're done you should post the result. It might be handy for others to try out.

Thank you very much.
I'll better start wiping the dust off my book "Object Making with ArchiCAD"
Ill keep you informed of my progress.
Thanks again

Im trying to understand GDL but it is hard. Would a savvy GDL guru transform the glass block wall library part to a vent block wall and post it on objects on line? Ill gladly pay for this library part. Is is a very popular
"window" in the tropics. Im sure the programmer could make a profit this type of window since it would have a lot of demand.
The advantage of starting with the glass block wall library part is that it could be put on curved walls also.
