Ok, lets concentrate on the tip now. This is all that is left after all.
Using ExtractSrf extract the lower surface:
Now, using DupBorder, create a circle out of this surface. Then we need to play with CPanel a bit.
Click on the Perspective caption in the viewport with right mouse button and select under Set CPanel->To Object.
This is how your CPanel should be positioned now:
Ok, now Offsetting the circle we recently created will work from Perspective viewport. So, select the circle, and Offset it by 1 units inwards.
Next, using Trim (or Split) split the lower surface.
Now, with the part of that red curve we have on the image above, we will create Sweep1 surface from the edge of this yellow surface. It would be great to first shorten the red line a bit. We will do that by creating a Point on it using OSnap option Near.
Split this red line with the Point. Now, using the lower surface edge and this bigger part of split line we will make a surface with Sweep1 command:
Join everything with Join command, and with Cap cap the object. Then with FilletEdge fillet the edges with 0.2 as radius:
Using Line create a line like on the image above. Using OSnap End and Quad options might get this easier. Then with Extend command extend that line a bit:
Ok, still in the perspective viewport because we have CPanel set the way we want it in that viewport. So, using Offset command offset this line left and right by 0.1 units:
Now, create a Circle from the center of this tube. We have the line in the center, so just point your cursor over the end of that line and input 1 unit as radius:
Using that circle, we will Split those two lines and delete the short parts:
Then, using BlendCrv command, blend the two lines:
Now, Join the blend curve,and two lines. After joining them, using CloseCrv command close the set of curves into one closed curve:
Now, we need to move that closed curve along the center line. Just move it a bit, like on the image below:
Using ExtrudeCrv extrude that rib (use the Cap option and set it to Yes):
And for the end, use ArrayPolar command and array those ribs in total of 14 times around 360 degree:
Ok, and in the end you should have something like this:
used 31 commands
ArrayPolar, Blend, BooleanUnion, Cap, Circle, CloseCrv, Copy, Explode, Extend, ExtractSrf, ExtrudeCrv, FilletEdge, InterpCrv, Join, Line, Loft, Move, MoveFace, NetworkSrf, Offset, PictureFrame, Pipe, PlanarSrf, Point, Polyline, Project, Rectangle, Scale, Split, Sweep1, Trim
Your website and tutorials are really interesting even for advanced modelers Thank you and good continuation.
How do you have the pieces look already rendered like metal in the perspective view? Is that a setting in V-ray?
use “Prettify my Rhino Experience” tutorial for setting up the AuxPacker viewport, then instead putting that blue material into Environment slot, put some other Metal material.

Yep, I forgot to load AuxPacker! ๐ One thing that is somewhat hard for me in this tutorial is the BooleanEdge and FilletEdge. I can’t get it to look right! Any suggestions or tips?
well, when I was writing this tutorial, I actually managed to work with FilletEdge, but when I was preparing the object, I had to do pipe method.
The same method I used for the diving knife’s handle grips.
Ivan I’m having some trouble with the NetworkSrf command, I can’t get it to work, I have my 4 Curves the way you have them, but somehow the round square edges are separated in 3 not two, is it maybe because of that??
what can i do to join them into only two?,
thanks
yes, that might be the problem. have you tried selecting all three of them instead two like I did? Or did you just use two. It should work even if you have split edges. Just select them all.
Let me know if that works, if not, I’ve got another solution ๐
Great tutorial! These are just wonderful exercises to train the basics of rhino!
Absolutely one of the worst Tutorials for Rhino I have every seen. Very little explanation of steps, tools, commands, or desired end result. One portion literally acknowledges a flaw with geometry creation and filetedge command but offers no solution. Not for beginners- a terrible Tutorial for anyone starting out with Rhino.
