Hi guys,
I have just started modelling with Fusion360 and I`m only a beginner. I have been working on this project for a few days now, but I can`t seem to get over this problem. I need to make a smooth transition between two lofts. When I stitch them together, there is a hard line between them.
I have tried using Filet, but it cuts off the tip of my design like this:
I would be very gratefull if someone could help me get over this problem. Thank you!!
You need to learn about surface continuity as a CAD/surfacing principle... there are different types of continuity between two surfaces that are connected:
G0 = Touching/Position
G1 = Tangent (same angle)
G2 = Curvature (same radius)
G3 = Torsion (rate of change of curvature)
You should see these as options in the Loft command as below, but in your file it looks like you've chosen sketch lines as the profiles and for continuity to work you need to actually select the edge of the adjacent surface or there's nothing for it to be continuous with.
Note that some types of continuity for some geometry won't produce a valid/useful result because the constraints create self intersecting surfaces or just force the surfaces to do wacky stuff.
You also have some control over transition between surfaces by using the "Direction" option and manually adjusting it, or by using guide rails.
I think for a beginner, this is too advanced of a project.
I'll link to the Autodesk Alias Theory Builders so you get a better understanding of what you are working with when lofting. In general, however, this project would contain a good amount if individually lofted and "connected" patches, and as such a large amount of sketches.
I personally would model this with T-Splines.
Also, fillets should only be done when you have completed all of the large surfaces, so mostly at the very end of the timeline.
