|Dear GEANT4 geometry experts, I got my first my first modeling challenge. I was given the drawings describing accurately a Linac Flattening Filter that is usually loosely modelled as a cone sitting on a small cylinder. I am requested to model it as from the drawings where the external surface profile is defined by an ordered set of (x,y) coordinates (plase, see attachment). I can interpolate the given points through MatLab and fit a curve. The external FF surface would be generated by rotating the plane curve around some straight line (the axis) that lies on the same plane. I believe Geant4 allows to build such Revolution Solids. I never dealt with that before. I would greatly appreciate seeing some examples of similar cases. I feel this is likely to regarded as a special component. Thank you so much Best regards, Mauede Attachment: http://hypernews.slac.stanford.edu/HyperNews/geant4/get/AUX/2016/04/26/17.50-40923-ernal_Surface_Profile.pdf|
