i want to draw a 3d spline between to points that are not in same plane , it's important that this 3d spline matches with the pictures line in top view and right view , but when i match 3d spline in right view it's don't match with top view , so how i can match this 3d spline with both top view and right view of my picture ?
i attached my file
in this file i want to draw a 3d spline between curve8 and curve9 that matches with top view and right view of same line in picture
Just draw two separate 2D sketches, each one will contain the desired shape as seen from the side and top.
Once your sketches are done, use Project Curve to project both sketches onto each other. The resulting 3D spline will have the shape you are looking for.
is there anybody knows how to control 3d spline ??
