Using the Fine/Design3D module
an diagonal water pump with 4 blades of blunt leading edge and trailing edge. while using the simple Bezire curve(GA,B1,B2) to construct the camber curve, I limit the thickness distribution to be constant parameters. the free parameters are the 3 angles of camber curve(GA,B1,B2); the two angels of Lean Law. however, i could not control the lenth of camber curve in every sections which will change with the angel GA. of course i could limit GA in every section as a constant value but it is not the case actully. i don't know whether i have post my problem clearly. the forum do not support picture uploads. if you want i can email my bad DATABASE SAMPLE to you who send me emails.
it's my first time to use the Fine/Design3D module.
