I would do it in two steps. First loft w/ sharp corner or beyond body surface and intersect body. Then either fillet or create lofted blend.
Hi thanks a lot for your response!
I don't know that many of the features of Solidworks, so I'm not sure if your suggestions refer to features, or are a description of what to do...
'Fillet' is under Insert > Features > Fillet / Round
'Lofted Blend', 'Loft Beyond Surface' and 'Loft Intersect' these are a description right and not Solidworks features?
"Lofted blend" is not a feature. What I mean is make a second loft for the blend if you need something more complex than a plain fillet.
Hi thanks for getting back!
So what would you use to define the two lofts please? As in one from the body Face to the first sketch, then another between the other sketches?
I shall try that now...
can you post your part here so we can take a look
Hi Christian, thanks for getting back!!
I got someone to send me images to show the issue…
Here is the kink in the loft… (it is a normal loft and starts tangent to face)
Here is a boundary loft instead either tangent to face or curvature to face. It has the kink still, and boundary loft tangency to face, it also has a groove where the loft starts.
The part you uploaded in your mesg which I downloaded and open in SW, looks fine (as showing in my msg with zebra stripes)
and you got images from someone without a SW part included, then it's hard to find out the issue
i saw your model and have some sketch mistakes,
this pink sketches have more points/divisions than the others points, to the loft works well you need have all the sketches with the same number of points/division, You cam add points more to the others sketches using 2d split or use "fit spline" in the pink lines to convert and reduce number of division.
you need put all end lines to vertical or tangent if you want tangence ends:
and to make better planes to draw try to use splines points:
you can do better section planes to draw with splines perpendicular, first draw a spline in the middle, start another sketch add some points coincident to spline, after that
make planes using this points and the spline..
i hope helped.
Thanks for your response!
Yes indeed, some of the sketches in the body didn't have enough perpendicular relations to mirror properly. Idk why, but it was putting a perpendicular relation at only one end of the spline and not the other end, or if I moved the toggles for the spline, it didn't keep the relation. My quick remedy was to just delete and re-draw the splines. So...
The mirror plane is now neater.
As a test, I made the profile sketch splines in the 'tail' of the chicken just one spline like this:
And that solved the problem with the leg loft I was having.
So as you suggested, the issue is the more complex geometry of the 'tail' compared to the body.
I used Fit Spline on the three sketches on the tail that previously were two straight lines, a sketch fillet and a spline.
They solved the problem with the leg, but created a new problem along the bottom edge of the tail.
I think I will re-create these sketches using a different technique than before which was not ideal.
So I think the mistake was in the tail loft profiles to use sketch fillets on the bottom edges.
They destroyed my driving dimensions, and I couldn't change them afterwards (without the spline going bananas)
I have replaced the spline + sketch filet with just a spline and it means I can toggle the dimensions of the bottom edge much more easily to soften the transition from the body to the tail.
