BIM Q&A | How to Draw Polar Coordinate Spiral Lines Using CATIA
I am working on designing a centrifugal fan radiator. From the information I have gathered, the turbine casing of a centrifugal fan is shaped by a gradually expanding curve. I would like to ask the experts: how can this curve be accurately drawn in CATIA?Drawing this requires the use of polar coordinates.
