ProE Airfoil Extrusion? How?

ProE Airfoil Extrusion? How?

ProE Airfoil Extrusion? How?

(OP)
How can I extrude (or cut for that matter) an airfoil shape in Pro/E?  I set it up by creating datum points from a text file (airfoil coordinates).  I then create a curve through the points.  Easy enough.  But when I try to extrude the airfoil shape, I cannot seem to dimension it properly (read at all) in order for Pro/E to define the section.

Can anyone help me with this? Thanks. -CBB

RE: ProE Airfoil Extrusion? How?

I have personally done this several times. I used quite a few datum curves, around 14 total, to drive a BLEND. I always made sure that the amount of vertices were the same with all of the curves, it used to matter and it still may. I would create the airfoil in a solid and finalize the cast part before copying the geometry to the final machined part.
Hopefully, that helps!

RE: ProE Airfoil Extrusion? How?

We generate a <filename>.ibl file for aerodynamic forms used in steam turbines. The format is below. We split the aerofoil into four curves the nose and trailing edge radii and the pressure and suction surfaces.  We generally as a rule use 50 points on the pressure and suction surfaces and 10 on the nose and trailing edge radii.

Each curve has a point no. x y z co ordinate with the last point of one curve being the start pont of the next and like wise with the last curve the end point is the start point of the first curve. Multiple sections can be used spaced out according to your requirements

Pro/e will read this file directly and therefore can be used to produce datum curves surfaces or soilds from the file.  We use this format to machine our blades using pro/nc

protrusions can be created by feature create solid protrusion from file

curves ans surfaces are created the same way

hope this helps
