Cladding Material Techniques
-
Looking to model and old design I did years ago, has anyone got any tips for modelling vertical boards and corrugated iron.
The vertical boards I imagine would be best to just make a profile and extrude to the lengths I need.
But as for the corrugated iron, I am not sure. The building has flat sections of roofing but also some areas where the roof is curved.
Any suggestions most appreciated.

That's awesome, thanks!

Word of warning on polygon count...
The example is fine for what was made... but imagine that multiplied up over all of the walls in a whole building - the poly count quickly gets very high - every additional edge and face you have has potential shadows to cast and receive etc... it'll s_l_o_w things down considerably...
Detailing closely seen small areas as was shown is fine... but if you aren't going to zoom into it why not use some simple pattern like equally spaced vertical lines over a face - that'd be say 11 times fewer edges and faces on each wall - even a trapezoidal section would have say 4 times fewer [and still cast shadows], or you could try a texture that looks like the ribbed cladding, giving you just the one face and its bounding edges per wall panel !

another way is just to change the arcs amount of lines to a minimum of two...

That is not very 'low poly' - it has ~500 faces and ~1480 edges per linear meter of wall/roof (the height doesn't change the poly count for a single sheet). This version has more than double the poly count compared to the earlier version in this thread - because it is now double faced !
If you processor dies at ~10,000 polys that allowance is soon going to taken up with this componnet if it's used a lot of times - even forgetting the rest of the model - used in small areas it's fine... but for expanses use other less intensive techniques like textures or reduced segment curves etc...

Point taken!

ok here go this is lowpoly and should work with a few more of them lying around..
if you need to use heaps of them just go for a texture that reproduces it, like maybe a bump map??

Better...
However, you left in some unnecessary verticals which were coplanar - here's the version with them removed. That's about a quarter fewer verticals ! See how much smaller the purged file is too...

Dear TIG,
A slightly lower poly model using a repeating component, just to prove that I do listen to your good advice.
Actually, my last attempt confused file size with number of entities. I now open Model Info when drawing a component to see how I'm doing.
Kind regards,
Bob
