Does anyone know how to create a screw with variable pitch, conicity and circular profile used for the variable sweep?
I managed to build the coclee with the variable step and with a conicity but I can not change the circular profile used for the sweep.
Could anyone give me any indication?
Thank you so much!

If I understood correctly: the section is a round with variable section, the trajectory is a variable step propeller, but I did not understand if the trajectory is conical.
However, if you need to change section, you need a loft, the trajectory should be inserted in the driving curves.

exactly, even the conical trajectory.
but with regard to conical trajectory and variable step I did not encounter problems.
the problem is to vary the "round" along the spiral.

I also tried with the loft but it doesn't seem to work as I wish.
I would like to be able to give diameter values based on the point where I am on the spiral, but it seems not possible with solidworks.
with creo it is possible to create a chart and to change a paramentro according to the graph.. .
is there the possibility to do the same with solidworks?

I've never used such a function, I don't think you can do it.
what I would try to do is to create the curve of the trajectory and on that curve build the sections that allow me control.
