More about mesh

I am drawing a mesh that has an slope besides a road. I want to make a sidewalk of 1 meters, so what I need is to copy the boundary of the road and bring it back to the slope so the "Z" coordinates of the boundary will be kept into the slope making the parallel line for the sidewalk. Is it that possible?

https://www.youtube.com/user/ispyridis/videos maybe these videos will help you along a bit.

Sitework modelling in ArchiCAD isn't that easy due to limited tools (unless you luck out by living in a flat part of world and can just use slabs for flat terrain like me).

I think Graphisoft has a video where they model the great wall of china using the railing tool, so maybe some creative use and abuse of other tools will work since ArchiCAD21.

I'd try to stay away from morphs, as they are very annoying to manipulate after you created them. Great for extruding along a path, but you can't really alter the path easily afterwards.

Hi,

Do you mean you are trying to add a sidewalk next to a road, and you want to keep this sidewalk at the same contours of the site mesh? It's easy if you draw in the sidewalk, then copy the sidewalk lines and site mesh to the side. Next, magic wand delete the mesh area outside the sidewalk. What you now have is a mesh of the sidewalk. Simply move this mesh back to its correct position. Now you have your sidewalk mesh inside the original site mesh. You can just use solid elements to upward extrude the original mesh from the sidewalk mesh. you can also drag a copy of the sidewalk mesh down of say 50mm (or the thickness of the sidewalk), then use the lower one to solid element operate the upper sidewalk. Put the lower one on a hidden layer. Then what you have is a 50mm sidewalk mesh on top of the original mesh at the same contours.

AS I can see with this procedure I got a sidewalk with the same contour and "z" on the road edge, but in the interior edge of the sidewalk, the one in touch with the site mesh, also have the contour of the road (say 1 meter wide) but the "Z" are still the "Z" of the road side and the mesh site on that edge will conserve its original coordinates without adapting itself to the "z" coordinates of the sidewalk. At that edge we will have an step up or down, depending of the site mesh construction.

I think I lost you slightly, but you can always just drag the mesh up or down? Maybe send an image.

Darwinland, following Piet, the side walk should just be a duplicate of the site mesh where it overlaps the footpath... unless your road is part of the same mesh?

If I do that I get a sidewalk but with the section/slope of the mesh, and the sidewalk need to be horizontal or not much than 3% slope.
