SolidWorks Beginner tutorial 7: Combat Knife - Part 2 (surface modeling) 

I don't know if this channel is still active, but I love your workflow with the smart dimensions dictating the shape the curves take. I do have one question: How do you arrive at those values? Did you pre-measure a knife that you are now modelling, or did you just tweak the values until they were the way you wanted them and wrote them down for this tutorial? I'm not new to modelling, but most of the complex modelling I've done has been with Rhino, so I'm not very familiar with advanced modelling techniques with parametric softwares as opposed to NURBS (thus why I'm watching the tutorial).
