[DesignModeler] How to fit a circle in trailing edge to model each sections of a blade?

aer · June 10, 2015, 08:14

Hi

I want to model a blade in DesignModeler. to do this I follow these steps:

1) use 3D curves to import airfoil's point of each sections of blade
2) use sketch projection to project this points to sketch.
3) use skin/loft to loft this section
finally the blade modeling complete

but, I need to fit a circle in trailing edge to model each sections properly, but I can't do it.

How can I do this?

Hi,
did you eventually managed to do that ? I am quite interested in the topic. Thanks in advance.

I don't get it. You already have the 3D profiles of the blade. Why do you project it to a sketch (even a 2D sketch eventually, which would change the actual shape). And you want to modify the trailing edge using a circle, instead of the actual trailing edge from your initial 3D profiles , is that correct?
