I am relatively new in regards to surface modelling in solidworks. I looked through a few tutorials but still at a beginner level. I am trying to create this complicated geometry (file attached) using solidworks 2013-14 student edition (64 bit). I have almost got it down, but in the end, for some reason the surfaces dont knit. Could somebody help me in this regard and also mention what mistake I am making? I need to complete this project soon and any help is very much appreciated.
