Hi Eng.X

I wang to learn the modeling method about impeller, picture as below, who can kindly share a .prt file with paremeters or the thinking.

I`ll start with sinking and later try it.

in sketching sk1 draw a circle dia as the
size of the base impeller and add 9 lines
aligned to the circle center length as in the impeller.

sk2 in a plane above the sk1 plane in
a distance as the impeller height
do the draw as the first sketch and
size as in impeller.

now a swept from the sk1 lines to the
sk2 sk2 lines
 
In the picture I see 2 different swept guidelines so its needed 2 swept
and then a circular pattern.

you can measure some points on the impeller
for draw guidelines splines for the swept
and then thicken the sheet or maybe
needed swept a rectangular shape instead
of a line
 
Do you want to learn the "demonstration model" or the "true production model" method ?
- Very many , or really most of the modeling examples seen on youtube shows "demonstration models" and never the true stuff because the true stuff is so much more complicated.
I do not know how many examples of "propellers" i have seen modeled on Youtube or shared at Grabcad, and none have been done by somebody who knows anything about
propellers, or the manufacturing of the propeller, or the aerodynamic/hydrodynamic requirements, the casting issues or the etc etc...
I myself know almost nothing about propellers but i have worked together with several persons over the years that do know.
I this case i could provide you an example which looks similar to the image above, created by a few features, but it will not take in consideration anything about aerodynamics or manufacturing or casting or material or...

Regards,
Tomas
