cubico o lineare?

[MaiMollare]

good day and good year to all.
I created a scroll surface using the default option first: linear interpolation and alignment by parameter that gave me a lot of problems in terms of boolean fittings and actions.
while using the cubic interpolation option and alignment for points I managed smoothly to complete the solid.
someone can tell me the meaning of these terms: linear/cubic interpolation and alignment for parameters/points?
Thanks again

Hi, the speech is a little long and I try to condense it.
for cubic or linear interpolation I suggest you look at the icons in the face blend command (for example) under the law tipe option of the radius value. In practice, two points can be combined either through a straight or through a cubic polynomial (but the icons are more explanatory).
the alignment, on the other hand, is to mean how points are joined on contiguous sections, for example if I have a section consisting of three segments and one by two segments if alline by parameter you will see the isoparametrics that will have a certain trend (for this purpose go on preferences>modelling >general and set to a value 7 and 7 the values u count elle lines and meti viewing wireframe) with other arcng
problems you may have had in the blends or other operations can be caused by the preserve shape option that I see disabled. here too the speech is long and is explained well in the help.
Hi.

Hello baskets
I created a very simple piece of only 4 sections using the different options you explained to me and now I can see the differences well. Now the difficulty is to understand what it does to my case and what is not, and what is the best compromise. Thanks again

It seems to me the right way to operate!:finger:
