parametric grills for arc window

[Ning Zhou]

see attached jpg, the arc radius will change according to window width / height, but still have to figure out the way to make parametric grills (symbolic lines for now, grill number will change according to window width), parametric array is the obvious choice but how to "cut off" unneeded portion, i did tried masking region in GA or DI w/ or w/o nesting, maybe the only way is doing separated for each type using visibility parameters!?

You cuold use a void but the problem is that the newly created elements after you create the void wont be cut. Which means that if you go to 2 mullions then back to 4, the 2 middle ones wont be cut.
You can use visibility though without any problem.

If all you need are the lines you can create a material with a surface pattern set to the spacing of your vertical divisions and use it for your glass.

thanks all for your reply, i think i figured it out,
for 2D version, nest DI w/ parametric array of symbolic lines + masking region, but i have to uncheck "Draw in Foreground" which is the reason why it didn't work before.
for 3D version, i'll apply the same principle, but replace symbolic lines w/ model lines or solid, masking region w/ void, hope it works too.
