Topic: Civilsurface getpoint?

Hi Alan!

Thank you for your fantastic work you´ve done. I´m so happy it works perfect. I must testing little more, how it works - doesn´t have much experience with surface-vla-objects.

Feel free to ask any questions. I basically make a selection set in the beginning of the routine, which will also prompt the user if there are nor valid/visible surfaces in the drawing.

From there, when the user picks a point, it iterates through the list of surfaces and if a valid elevation is found (no error thrown), it displays it for each applicable surface.

BTW, I had to make a small edit to the code; forgot to localize my 'o' variable.

how to select surface by layer

If you are trying to only select surfaces on a specified layer, you can add a layer filter to the ssget function (cons 8 "LayerName").

Something I did ages ago now was to make my own toolbar interface for handling CIV3D surfaces I felt the toolspace method was too cumbersome so my tool bar has buttons for the most used contour settings as well as a button for off. You do not have to display any surface currently for it to work as if there is only one then it auto sets it if more than 1 then a dcl pops a list of all surfaces to pick the one you want to set. I must also acknowledge Alan J T for his help getting into the surfaces.

The full code is in this zip including ICONS Toolbar lisp etc. You could use the select surface part before adding a point.
