Best way to round off a lofted end?

patrick_horn

I'm just learning and messing around, making a fishing lure body, and I used circles and lofts with guide lines.
However I'm not sure how to round off the ends. The only way I can see doing it making an ultra tiny circle at the end so it appears around. However I'm guessing there may be a 'proper' way.
Was hoping for some suggestions

Here's how I would approach it:

The starting base body (note the intentionally weird/difficult end profile)


The loft to cap it off (note the "tangent to profile" end condition for the point that you're lofting the face to as well as "match tangent" for the face on the main body)


I had to do this in two lofts instead of one continuous one, but I'm also no expert at surface modeling, so there is probably a better way to do this. Hope this helps!

@patrick_horn You can also use the fill surface feature to round off the end of a solid or surface. Here is my approach.

Offset surface. This will be used as construction geometry. The surface will be used to match tangency for the next operation. 



Fill surface matching tangency. The guide option is enabled and the vertex is selected to control the shape of the patch. 


Finish by enclosing the surface with the solid part.



The end result. Let us know how you make out!
