I want to create a 3d sketch to trim certain part of the object I have. So I created points on the 3d surface and then connected the points using 3d spline on surface. However when i use this sketch to use as a trim entity, it gives me an error (see image attached). I am not sure why it says that the 3d sketch doesnot intersect. Any insights on this or work arounds for this situation? How can I check if my 3d sketch is coincident on the surface or not?
