Problems with void extrusion.

[mrheuseler]

Hello,

I'm about to make af balkony-front. An extrusion of 1100 mm. x 3000 mm. 2 mm. thickness.

In that extrusion, i need to have some perforations. 9x9 mm. squares. (holes). 

I'm using Void extrusion for that. 

The problem is, that Revit freeze constantly. We are talking about 7-8000 perforations. And that might cause the problem. (Problem in picture!)

Any way - how would you do it? 

Thank you.

Kind regards

Morten

Too many tiny voids will cause just that. Use a material with a cutout map and a surface pattern. Revit already has a few perforated metal materials in its stock appearance asset library.

8000 1100mmx3000mm perforations???   Is this a misprint?

Ouch...normally tiny void is counted as individual objects. It will slow down Revit. Best way is to use texture map and do cutout texture map to achieve the same look. If you want the model look, I use Curtainwall with preset mullion spacing. However it gets really heavy and not practical. See attached for sample.

oops. my bad. 8000 9x9 mm perforations. So, a total area of 648000 mm. Not 3300000.

Out of curiosity, what's the spacing?  

For whatever it is worth, you may want to turn OFF Thin Lines and consider Line Weights and View Scale.

Other than the material with cutout, you can also try to model it without void.

You don't have to model the whole panel, maybe do it as 550mm x 500mm panel, then place them together.

Drawn in the extrusion sketch @bin means I suppose (havent looked, but just edit the file to see).

@martijn_pater Yes, either single solid with multiple opending in sketch or multiple solids. They all work on my crap computer. I am not going to try the void method, it will definitely kill it.  The single solid one is properly faster but the multiple solid method is easier to adjust or made parametric.

watch out with coutout map.. cause you must delivered the texture together with the project/model otherwise won't be visible. so it's not embedded in the rfa.

That is a great idea. Actually, I had that in my mind. But i thought, that voids would be the "easy way" - but no. 

Thank you.

[mrheuseler]

I have thougt of that way too. 

Might be the way to split the panel. Thank you!

Actually, the company just want the renderings. Not the entire file. Otherwise, you have absolutely right. 

The texture have to follow!
