Hello everyone!
Im currently working on an impeller as a school project, with a list of parameters that Im going to be able to change. Things are going pretty well, but I have some problems with the impeller vanes. They are defined by three curves using equations, and then I used boundary blend between curve 1 & 3, and 2 & 3:
dw = diameter of shaft
dl = length
Wys = height of vanes
Alfa = thickness of vanes measured in degrees
L_VANE = Number of vanes
Curve 1:
r = dw/2
theta = t*360/L_VANE
z = t*dl
Curve 2:
r = dw/2
theta = t*360/L_VANE + ALFA
z = t*dl
Curve 3:
r = dw/2 + t*Wys
theta = t*360/L_VANE
z = t*dl
These values are defined by parameters. I have no problems doing changes when working in part mode, but I dont know how to change these curves when working in assembly mode. I know how to change diameter and length of shaft using d#:#, aswell as changing the number of vanes. But the shape of the impeller vanes wont change when I change the parameters.
Does anyone have any ideas for what to do?
Heres a picture of what it looks like.
