Can anybody tell me how to make a corro Custom Orb Sweep?
I tried to import a DWG file and make it into one much like you would for a beam.
It didn't work though.
I would like to attatch it to a wall. Do I make it a wall sweep or what?
Is it possible?

occasionally on the header of this web site is a link to australian lysaght and stramit roofing profiles, including revit ones apparantly. never done it, but maybe start there? not sure how you convert the profile into a 'sheet', maybe an in place family? the experts may be able to help there!

Latemore is referring to www.steelselect.com
First let me begin by warning, modelling corrugated sheeting would be a huge overhead for revit (especially if you made it parametric). Its definitely possible, but depending on how much you have you may reduce your performance to an unworkable state.
In preference you better off just showing a roof the same thickness as the corrugated sheeting then using a repeating detail in section to show the corrugations and hide the roof edges...

do you need the custom orb to show in hidden line and shaded view or also in a rendered view?
for the forst ones, just add horizontal lines to represent the custom orb, if you want to show in render use the attached maps, you will need to play with them a bit to get the colour and the scale you need

The idea was to be able to draw it once and have it produced in all views,
detail and render. I was trying to get away with having to draw it each time in detail views.
I would have to change the wall thickness to allow for it. I also like the idea of producing Isometric detail.
Thanks.

I have done this once, was a while ago and I don't use revit much (mainly do engineering) so my memory is a bit hazy. I definately downloaded the profile from steelselect, was a closed line polyline dwg file. Then used this as a wall sweep. The main problem was the wall was not an exact sheet size, so had to trim the polyline to get a size to make up the remaining part sheet. The polyline is exactly drawn so the sheets overlap exactly as the real thing (provided you lay them using the same edge).
I didn't notice any difference to performance, however was only using it as a feature on one wall. Did I also use to show a roof edge without guttering...?
Having done that once, I have since used the method described by eldados - much easier in the long run and works vertically too.
The textures are also available on the steelselect site.

Seems like i should read better... Didn't read the heading properly and totally missed the fact it was a wall. Sorry.
Eldad's way is the quickest and least performance deteriorating method.
You could also create a wall hosted generic model that is parametric in width via an array, however you'll get lines in elevation where each sweep ends...
Another method would be to draw a specially constructed curtain wall that uses a panel created via the custom orb profile, this would be the easiest to adjust/create. But will still result in a performance hit.
Weigh up how many of these walls you are going to create. If there more than 10 substantial size walls i suggest not modelling it.

Thanks
All for your information I tried all of your ideas. Steel Select have all of the bitmap textures for Colourbond and standard Custom Orb corrugation.
As I am only doing a small amount, the actual 3d texture by way of curtain wall looked the most realistic in render and section. (thanks Mr Spot)
A question is though, how can I create the detail so it repeats in its vertical? As I make the wall higher the profile only goes to it’s 760mm cover. It does not have any problems in its horizontal.
Can anybody help?

Create it to a sheet size... Then add horizontal curtain grids to the height of each sheet size and swap out the panels again.
For any odd height extras. Duplicate your custom orb panel family and add a parametric void at the top to cut to the correct size (give it an adjustable height instance parameter)
