    I have offset table of a propeller,that is x,yo,yu at different z and r/R. so is there any specific software to design the propeller ?:?:

    Sounds like the propeller has already been designed, if you have the offsets for the blades.

    Input the data into a CNC and it will make the propeller

    Propeller Design

    I need to draw a 3D model with these data,I can't figure out how to give skew angel to offset, the offset given is without skew. How do I get the new offsets with skew ?
    Again I also have to give rake angle . please help
    I am an student.

    Is the table of offsets and the 3D modelling in the same software programming?

    What is the source of the offsets?

    What software are you using? What other projects have you done using the software?

    Where are other students getting the knowledge to complete the assignment?

    Offsets are from a research paper from 1989,I am trying to model it with AutoCAD. There is no other student working on this.
    My question is simple,if I have positions(coordinates) of airfoil section at different r/R and now I need to give ,say 15 degree skew angle,what will be the new coordinates of airfoil section ? is there any specific naval arch. software to give skew angle ,or I will have to do it mathematically ?

    Well,I just found position of skew line at different r/R,that makes the work very less complicated.

    I thank all people for giving their inputs.
