Designing Spiral Concentrator in Salome

 

Hi friends

 

I want to create a Spiral concentrator which looks like something below:

To design the same, I have made the face and a spiral path profile. I am trying to extrude this face along the spiral path. However, it results in peculiar extrusion. Seems like face is following the spiral path but the direction of normal keeps unchanged (as shown in figure attached). What I want is that normal to face direction should follow the spiral path itself, or say the face is always normal to the path. 

How this can be achieved. 

 

Thanks in advance.

Hi

Try using Extrusion Along Path with Z axis as BiNormal Vector (second construction way).
