I try to convert this 3d-scanned propeller into a surface- or solid model.
As you can see I created sections/curves using the restyle tool (intersection with different planes).
Then I exited the restyle-feature and tried to use the loft/blend-command to connect the section-curves, but I i coudn't select the section-curves.
Then I used the style-environment and was able to create a surface between some of the sections:
That worked well, but when I tried to add another section then the profile is twisted:
There is a white point (starting point ? ), but it doesn't happen anything when I move the point on the curve. It jumps back when I release the mousebutton.
The other side looks like this at the moment and I'm not sure how to propperly close the surface.
Is my approach the right way to go or is there a better way ?
How can I get rid of the twisted profile ?
And how would you create the other end of the propeller ?
Is your name a play on "Mike The Bike" Hailwood perhaps?
I had a part scanned recently by our in-house guy, and while he made a model from the point cloud manually, it was only because he didn't know how to use the software he had but didn't get trained on yet. I forget the name of it, but there are software packages out there that will take the point cloud data and make at least a STEP file out of it. I think your best bet would be to find one of these packages and purchase it or find a free one. I've done things like this before back in '04, and it is a PITA.
Best of luck!
With regard to working with scan data to convert it to surfaces, Geomagic has solutions that are best in class for this work in my experience. Curves and surfaces can be created and imported into Creo.
The trick at the closed end is to overbuild 4 sided patches and trim them to close the quilt.
I can not comment on the lack of control for the start point without seeing the model. I can tell you that if you are working with a swept blend feature you may not have explicit control of the start point of the sketches within the sweep feature UI. You may have to go to the parents where the sketches are defined to alter the start point. They need to be mapped to prevent "twist" of the surface.
If you are trying to create engineering driven aerodynamic surfaces then the approach is probably different.
For aerodynamic surfaces .ibl files are used by some design teams that work in Creo to develop aero surfaces. The .ibl files are imported and the surfaces are built using them as a reference. The Aero and Thermo teams generate these curves which are then imported into Creo and used for geometry development. All of the geometry development teams I have experience with use core Pro/Surface only and do not use Style curves/surfaces.
I mention this as it is a propeller. For prop driven fixed wing and drone multi-copter blade design there are classical models that are used to create points within Excel for example to create the curves needed for an appropriate airfoil.
