I have some trouble with a surfacing job as in figures below and the attached .prt file. I think I have good knowledge about Through Curves and Studio Surface, but really feel frustrated with working out a smooth surface successfully.
All the blue curves are input curves. I have checked to make sure the top spline is smooth/tangent.
Great thanks in advance for your help!
ps: I don't know why a prt file can't attached and always lead to a message "The contents of the attachment doesn't match its file type." Then I upload the the prt file by changeing the extention name to jpg. So you would need to change the file extension name back to prt before openning it. Sorry for that.
