Thanks

Hi!

Here is a gdl-object that "bends" the  texture. Works good.

You cannot. AC only does basic box mapping. The only thing you could do within AC is split your curb into multiple pieces and rotate the texture a bit for each consecutive piece... Outside of AC, you could create a custom texture that incorporates the curve.

Interesting. I wonder how it is done...

I would assume using COOR to align the texture for each segment of the polyline.

Lenovo Thinkpad - i7-1270P 2.20 GHz, 32GB RAM, Nvidia T550, Windows 11

But would that not set a consistant rotation for the entire arc segment, node to node. Or can you somehow incorporate COOR into a TOLER statement? Though I never looked into sinceV6's polyline object...

I think the "magic" is that from the looks of it the arcs are just divided into small straight segments, so the texture is never really bent.

It all comes to down to figuring out how to align the following texture segment.

Hi everyone.

Thank you for sharing my object.

 

Thank you also Graphisoft Community team and @Rubia Torres for the Honorable mention.

 

The object is realized using PGON{2} where you can define the coordinate of the texture on each polygon. 

You could also use TEVE; in this case the texture will be deformed but more realistic. You could have problem in 3d export for renders in other software.

 

This object use the same macro to realize all my railings objects you can find here: http://www.3dmediadesign.it/objects.html.

There are also other free objects.
