In this tutorial you will learn how to model this cool looking diving knife. The model can be set apart into two pieces, blade and handle. Both having some nice features.
I really liked modeling this model, it turned out really good, and I must say that it was pretty easy to model it too. However, there is fairly enough playing with Osnap, but then again, when do we not use Osnap frequently? Anyway, to get you started, you first need to download some kind of blueprints I made for you out of this model. You just gotta love that Make2D command!!!
First things first, we need to setup our blueprints. Not only import them into Rhino, but also position and scale to fit the dimensions marked on them. First, go to Front viewport. You can expand it by double clicking it. Next, using PictureFrame command browse for blueprints you previously saved to your computer. Now, you don’t need to worry about how to position or how big you should make it. We will fix that in a bit, but just make sure your blueprints are not tilted. For that you can use Snap, or even better Ortho.Create a line with PolyLine command or just simple Line command will do it. From the blueprints you see one dimension 145.08. That is just a reference dimension, and you can use 145. So, make a Line 145 units long and using Ortho make it horizontal. Now, the line will probably be bigger than the blueprint in PictureFrame, but that doesn’t matter because we will now scale the blueprint to fit the line. First, using Move command move the blueprints PictureFrame. Select PictureFrame, and start Move command, by clicking on the image, on the tip of the blade you define first point to move from. Then click on the End of the line for the point to move to. Using OSnap End option is smart thing here. Actually, without it you can’t do it accurately. Next thing we need to do to the blueprint is to scale it. Now, we have one line that is 145 units long, and we see on the blueprint the length of the blade. Using Scale command we will scale the PictureFrame by first clicking on the end of the line (or tip of the blade) and using Near OSnap option we will click on the line where the blade ends on the blueprint. Then, for the last click we will click on the opposite end of our 145units long line. Create another Line, and position it according to the blueprint vertical line that represents the far right end of the blade. Now, move the horizontal line to the Mid point of vertical line. Use Mid option in OSnap.
