I am new to SW. Is it possible to import the coordinates for a spline?
Insert>Curve>Through XYZ Points allows for you to import a .txt or .csv file with coordinates, and then it automatically creates a spline along those points.
If you want to just import sketch points in a 3D sketch, there are many macros out there that will do that. Then you can hand-create the spline on those points, with control of the handles. Do a search in the forum for "coordinate macro" or "point macro" and you should see quite a few links.
