    I'm sure the topic doesn't make much sense so I'll try and explain by way of example..

    I'm making a pond shape and this is what I was planning:
    Start with a flat sandbox grid (20x20m) 0.1m grids.
    Draw a complex shoreline on top (outside the group) using the freehand tool.
    Copy and paste in place the shoreline into the grid, so it is part of the mesh.

    Now... I want to select everything in the mesh that is outside of the shoreline object and delete it, and then lock the outside edges of the mesh (i.e. the shoreline) so that the x,y,z position of those vertices doesn't change. Then I can use smoove without fear of mucking up the shoreline elevation.

    Any pointers?

    thanks

      You can do this. Before pasting in the closed shape to the grid, soften the edges in the grid by selecting all of them and clicking soften coplanar in the smooth/soften window. After you paste in the shape, you'll be able to select the outside and erase it.

      I don't know that you can lock the outside edges in this process. I guess you just have to avoid them. Anyone?...

        Ahhh.. yes of course, I have seen that before - my brain just didn't want to recognise the solution.

        Maybe... and probably not too hard to do but it would be good to know if there is a technique to lock the shoreline in place.

        Thanks
