Hi Mark,
The roof surfacer is part of the 'roof accessories'. You select your roof first (this is critical to make the surface object associate itself to the roof), then go to the Extras menu, roof accessories, and select the Roof Surfacer object.
Within the object, under Custom Settings, you can select 'Corrugated Sheet', which sounds like what you're asking about.
Skylight holes will be automatically cut in the roofing.
Note that doors and windows can't be placed in roofs, so using the surfacer for your wall siding won't work.
The 'wall accessories' (also under Extras) has the potential to apply corrugated steel as siding ... but nobody has implemented that at the moment AFAIK (not in the standard library anyway).
You can find vertical corrugated steel in the US library under 09 Finishes 81 / Cladding 81.
Going with SEO's as you are is probably the most expediant way if you want the reveals dramatic. (An alpha texture - with a bump map for the ridges - would be fine from a distance.) Instead of your 2x2 walls ... there are some other options to try.
You can use the corrugated library part on a slab, and subtract with upwards extrusion to profile it onto a mass ... then save
that
as a library part, rotated to be vertical, and use the new library part (looks like a blank corrugated wall) to subtract from your wall (it'll cut the window and door trim too though).
Another option that I just tried is way too complicated - suggested (not recommended!) only for pretty advanced users, but works without messing up your doors and windows. Duplicate your wall (with windows/doors placed) and convert the duplicate to a log wall with the reference line in the middle to get centerline hotspots. Change the size of the logs so that they equal the desired radius, and space them one log apart. Change all windows and doors to empty openings (larger than original to avoid cutting away window/door trim.) Duplicate THAT wall and raise it one logs' width in height. Create yet another duplicate of the original wall; remove all windows and doors and make sure it is thicker than your log walls. Subtract one of your log walls from this mass wall to get one half of the sine curve. Now, overlap your other (vertically offset) log wall with this. The resulting mass should look like corrugated siding - and should be ready to subtract from the real wall. It won't though. I found two problems with SEO in playing with this that I won't go into. The net result was that the only way to subtract this shape from the real wall was to first save it from the 3D window as a GDL object, and then place
that
object and use
it
as the operator for the SEO. Whew. Did I say
not
recommended?
HTH,
Karl
PS I had assumed your handle was fake too. Sorry. There's a guy here with the handle "Fullalove". I figured that for a fake too, but it's really the guy's name! Have to not be so quick to judge.
