Wrong shape from Bladegen
 
I have a problem with creating of wind turbine's blade!

I want to import airfoil coordinates and create a blade.
I chose three sections in blade and import those *.txt files and the hub and shroud are chosen at root and tip of blade. procedures followed are as below:

And the software created this wrong model because it selected an incorrect axis with 9 blade like this:

Please help me to correct this problem!

Best Regards

hab & shroud's file format!!
 
I think the problem is in my HAB.txt & SHROUD.txt .
I create them by half of airfoil but I think it should have a special form

I am pretty sure that you can select the number of blades of your machine from the BladeGen options

Thank you vafiadis for your answer
But my problem is for create blade. My problem is in the type of hub & shroud coordinate and their shape, for create blade!

Thanks
