Thanks for the info, Unfortunately my old version seems to be lacking ( or I can't find it ) this preference feature / edit object I am using Vista 32 bit. It is puzzling as even the CAD tool for a spline line is not working, Curved walls work, curved deck edges work, curved fencing work, curved retaining walls works.
Splined terrian walls is not working, splined terrian curbs is not working, splined road and spined sidewalks are not working.
I am going to try uninstalling and reinstalling the software.
I am trying to put a curved sidewalk around a kidney shapped pool.
