take one thats done all ready and reverse engineer it.
Thanks Arstide.But it does not help me
What do you want " Shovel" or "Propeller" as in your picture ?
sry i mean propeller
I have drawn the cylinder form but i have problems with drawing the propeller with the needed angles
If you want to model a specific propeller, than is necessary to know diameter, pitch, number of blades, etc. In this case are you the only one who knows what he want.
Propeller is a very general therm.
As John said, take some of the existing models and reverse engineer it to learn how this works and than apply this on your own propeller.
Here are the necessary details:
Diameter of cyclinder : 25 mm but it curve 5mm
pitch: 45 degree
number of blades : 5
max.length of propeller: 48 mm
bottom side : 24 mm
