Attach your *.sldprt file here and end all doubt.
I recommend spending a bit more time in formulating thread title as well.
A good title helps in future searches by beginners researching existing information.
I would expect to see the term "Boundary Surface" in the thread title.
This is a question always arise after seeing many works in the YouTube. I do not have any particular file at moment.
Tangent Type Select one of the following:
(Available when you have a minimum of three curves in the direction.) Approximates a parabola scribed between the first and last profiles. See Start/End Constraints in the Loft PropertyManager. The tangency from this parabola drives the lofted surface, which results in a more predictable and natural lofted surface when matching conditions are not specified.
No tangency constraint (zero curvature) is applied.
Normal to Profile
(Available when the curves are not attaching a boundary feature to existing geometry.) Applies a tangency constraint normal to the curve. Set the Draft angle and Tangent influence (%).
Tangency to Face
(Available when attaching a boundary feature to existing geometry.) Makes the adjacent faces tangent at the selected curve. Set the Tangent influence (%).
Curvature to Face
(Available when attaching a boundary feature to existing geometry.) Applies a smooth, visually appealing curvature continuous surface at the selected curve. Set the Tangent influence (%).
Curvature to Face is for a curvature continuous face when attaching a boundary feature to existing geometry.
You can tweak the percentage of tangent influence to further "shape" it.
When tweaking the percentage of tangent influence is there any chance to come across “Tangency to Face” option?
