your videos are excellent! keep them coming!
Thanks David, I'm glad they're helpful. If you have suggestions on what types of modeling tools to cover in future tutorials please let us know.
Cheers,
This is a great tutorial. Short and to the point, but very clear. It explains a lot that I have been struggling with as a new Rhino user. Other modeling tools that I would like more info on are how to draw cross sections over an imported picture. I'm trying to model a swim fin which needs an accurate foot pocket shape. Can you help?
Hi Glen,
Can you give me some more details about what your trying to do with the swim fin? You can email me directly with any images or models...

Hi Brian,
Could you explain how you adjusted the appearance of your control points? They're much larger and easier to see in your video. Any help is appreciated!
PS - the videos are extremely helpful, thanks.
Hi Eric,
You can change the way the ctrl pts look through: Options>Rhino Options>Appearance>[the display mode you'd like to effect]>Objects
Then there's a field for control point size. I used 6 for the video tutorial and also had Anti-Aliasing on in the settings for the graphics card. This is what made them look round.
Thank you, Brian. As a Rhino noob, this was very helpful, and will help me with some of the ideas I have been unable to implement so far.
Hi, thanks for this tutorial; very helpful.
I'm trying to do something similar to what you described with "shrinktrimmedsrf" command toward the end of the video, but that command isn't quite working for me. I basically have some twisted rectangles that were surfaces, and I made them meshes so that I could make them all planar triangles, then I converted them back to nurbs. Now some of the shapes have control points where the corners would be if they were full rectangels. Rebuild doesn't work, so is there any way to get RHINO to remake these triangles with just 3 control points at the corners?
Thanks.
Hi 3rd eye,
That's a good question. The shrinktrimmedsrf command will shrink the ctrl pt structure back to the smallest rectangular boundary. To get it to look like there are only three ctrl pts you'll need to move one pt on top of another using your pt Osnap. However there will still be two pts there.
If you make a three sided srf using sweep2, you can get the structure you're looking for. It also sounds like you might find the PanelingTools plugin useful.
Could you explain again how you made the control points look round? Can it be made from rhino options?
Hi,
To make the control points round you'll need to do two things. First, change the control point size to 6 pixels (that's the size I use) in the display mode you're using. This is done in the options dialog. Second, to make them look round enable anti-aliasing on your graphics card... That's how the square control points get rounded.
I know there is a way to adjust the number of control points on a surface I just dont remmember not add but decide the number of control points.. do you know?? please I will apreciate the help
You could use either the command 'Rebuild' or 'ChangeDegree' to add or remove control points from curves or surfaces. Rebuild will change the shape in most cases while increased degree will not.
Great video, thanks!
