Hi,

I created a winding path (not straight) and would like my paving texture to follow that wind, ie to turn right and left along the path. Is there a simple way in which to do it? The simple orthogonal method looks terrible, doesn't t?

I think the method is going to be very dependent on the software you are using to generate the path. Are you using SketchUp? 3dsMax? Revit?

Thanks a lot for your reply. I am using archicad. Is there a chance?

That I could not tell you as I've not used Archicad much. There are several forum users here who do though, hopefully they will be able to assist you.

There were some discussions regarding this issue, and the conclusion is that, correct mapping of textures on irregular surfaces need a so called UV definition you can do only in the CAD.
First you map a texture in ArchiCAD - it can do that - and you transfer it into Artlantis. If you change the original texture with any Artlantis material (and choosing the UV option in the mapping list) you will get a correctly textured surface.

ArchiCAD's UV is extremely limited. It is not possible to distort a texture (paving stones here) to follow a curved path on a planar surface, which is what you want.

If you think about it, what you want in reality would be done with custom stonework. If you take the rectangular block image and repeat it and then curve it, it may be good enough, but would not match reality - the grout would be stretched very wide on the outside curves, and pinched on the inside. But, perhaps good enough.

I believe you have only two options from ArchiCAD: create a custom texture for the curved walk in Photoshop by repeating the desired texture and then distorting it, then assigning it to the surface in Artlantis and aligning it ... or create grout grooves in ArchiCAD by solid element subtracting little walls (etc) from the surface of the walkway and then apply one generic material to the resulting tiles and another to the resulting grout in Artlantis.

Cheers,
Karl

What you can do is to make a curvy surface with a slight pitch or angle. With that, Sketchup or archicad will automatically apply the texture accordingly.

I might also add that you could place each tile / stone individually.. For my money, I don't like a bunch of BOOLEAN (sorry, seo) operations in AC... I can't prove it, but I know there's a limit... Plus you've got to remember to show/hide them and update them as time goes on... and you cant see the result of them in plan (ugh)...

So, using the great MULTIPLY command in AC, it's pretty easy to layout stones quickly.

In addition, if you want them on a "MESHED" surface, I like the individual stones INTERSECTED with a mesh...

In either case, the grout can be a "Solid" laid just a bit underneath the Top of Stone...

Cheers!
