How do I achieve perfectly smooth transitions between surface lofts?

[Anonymous]

I am designing a handle bar for a bike, and have run into an issue when trying to finish the design off. I really like the shape of the bar with the lofts I have chosen (a mix between direction and connected) but the final result is something that looks off when I render it. all of the lofts have really noticeable edges between them. For some of the sections a direction loft will not do, it totally changes the shape of the section to some weird twisted snake looking thing. So I would like to, if possible, stay with the lofts I have chosen. Is there a way to seamlessly blend each loft togeather?

Very Obvious in the render rooms light as seen above.

Thanks!

Did you try adding a large radius fillet at the intersecting edge to blend it a little better?

Hi,

1. please share* your design to better analyze it
2. A row of single Lofts always lead to problems at the transitions

Instead of doing a bunch of separate lofts that each only have two profiles...try lofting multiple profiles at once.

Or, where you use the Direction type, try lowering the value to something very small, and make sure when you do the next loft, also make that joint the Direction type and use a very low value.

Or, fillet the joints between separate lofts.

Hi,

that´s what I was talking about

The straight sections of your handlebar should be separate lofts between two profiles.

When done with those, hide all sketches and select the edges of the existing lofts as the loft profiles. That will allow you to set the start/end condition to tangent(G1) or curvature continuous(G2). Tangency is likely what you wat here, so start with that.
