Model a propeller
Hey, i created a quick tutorial for you :)
Create an extrude
create a new plane(at a 45 degree angle for the prob volute)
Create a sketch and then a midplane extrude of 2mm thick. please note that i made a prop design that is not 100% accurate, just as an example. make sure you dont use"merge bodies" option.
added fillets to the rough edges and then selected the "flex" option from the feature list.
select the twist degree and tweak the "triad" values from the bottom left, they control much of the curvature.
Create a circular pattern, using the "pattern body" option. i used a temporary axis there as the central axis.
congratulations! you have succeeded :)
when finished, go into bodies, combine them and then you can cut, fillet and paste them with ease :)
