Hi there, we'll be making and posting new tutorials in the coming months, hopefully there will be something more complex available for you later in 2018. Thanks for watching!
Hi, we have given a link to the Illustrator file used in the exercise shown so you may use that for practice. The link is in the text introduction to this video - hope that helps. Thanks for watching!
Hi Fabrizio. Thank you for your question. Blend Edge can be thought of as being an aesthetic improvement over Fillet Edge. Blend creates a curvature continuous condition whereas Fillet Edge creates a tangent continuous condition. With the Environment Map or Zebra you can usually see a stop/start condition at the edges of a Fillet (this the effect of two different radii meeting at a tangent) whereas the Blend should look seamless. The Fillet is mathematically simpler and I would usually use this in less visually important areas where edges need to be softened and always where there were two planar surfaces involved. Likewise I would use Blend in areas of visual importance where a smooth continuous form needs to be expressed. This is a simplistic explanation - and in reality the difference and choice might be more nuanced - but I hope this helps. Best, Phil and the team at Simply Rhino
Thanks Phil... that was great.. I noticed that you quite often would opt for the 'shrink' option within commands. What is the advantage of shrinking a trimmed surface?
Hi Sean, The advantage in shrinking a trimmed surface is this - when you trim a surface, the original untrimmed surface boundary remains as part of the surface description. If you trim a small area from a large surface then most of the surface description is redundant. When you Shrink a surface the surface is re-approximated by Rhino and the untrimmed boundary moved as close as possible to the trim boundary. Hope this helps.
Is this a necessity?... Or is this just best practice due to reduction in file size?.. Are there any other advantages in working with a surface that has been shrunk?
Hi Sean, It helps particularly when you export geometry - if (for example) when you take Rhino geometry into SolidWorks surfaces that are not shrunk sometimes do not translate correctly. If you are staying in Rhino it’s not an absolute necessity but can help to create more usable geometry - as your control points do not extend so far past the trimmed surface boundary.
Thanks for your comments. This procedure isn’t regarded as being parametric modelling. The term ‘Parametric Modelling’ generally refers to a process where (for example) features can be changed after the model has been built and related features will update accordingly. This type of approach can be achieved with Grasshopper for Rhino and in a very limited way with Rhino’s History command.
The 'planar curves' function didn't really work out for me.. I've made a bowl and then an inner bowl like you did with the spout, but instead of making a surface between the two - like yours - it covered the entire area like a lid. Is this a common error? And is there an obvious solution?
Hi Jonathan. Are you referencing capping off the spout at 24:30? If so, make sure that the outer top edge and inner top edge are both planar and at the same height and both edges are properly closed up. If you then have two closed edges (or two closed curves) on the same plane, Planar Srf will give you the correct result. Hope this helps.
Thank you very much for this nice tutorial. I had trouble when turning the curvature graph on. A box pops up but nothing like the vertical lines show (28:55). Is this a common error? Thank you so much for your time!
Hi Happydrawing. If you adjust the scale (control is on the dialog box) of the curvature graph you’ll see the graph become larger or smaller. You’ll need to adjust the scale on a case by case basis. Hope that helps you? :)
Hi, I corrected the negative curvature as from an aesthetic point of view I preferred the curvature to be completely positive (convex). It’s a personal preference though - no other technical reason. Thanks, Phil.
After a video and a half I have to say this tutorial is informative but it does not serve as a guide. You skip 2 or 3 clicks that you don't even acknowledge on almost every command. And on your recording platform, you don't even enable the "right/left click" visual aid. I have to watch it, and hear the click (that is there just because you are recording ambient sound) and then try it with both mouse buttons. You disable and enable options and don't mention them either. Also, sometimes you take us through a whole process and at the end you say "oh and check project is off" so if it was off I have to go all the way back to do it again. I'm on minute 12 of the second video and I already know this is going to be a pain. Just take more time including everything you do. Rushing to show everything is fine, but you rush skipping details that make things work differently. Still thanks for the upload. Hopefully I'll finish soon.
To illustrate: When you make a line perpendicular to the curve it looks like this: You mention the length of the line. At the end of the process didn't make a difference. Then you go through the options while reading them. This is great. But then you just say "We are going to orient this so it's perpendicular to this edge". You skipped: LC on the line, RC to enter, LC on end point, LC on edge. Even when I finally figured out and did it like this, my line would be perpendicular towards the inside of the pot, instead of to the side. So I had to find a way to rotate it 90 degrees so it would be perpendicular to the edge but following the surface. This is just one command, but it has been like this on many others. I am not trying to criticize you out of frustration (ok, maybe a little) but I would like you to take this as 100% constructive. I know so much more now than when I started. I thank you for your effort and time.
Hi, We take on board your comments and will continue to make future tutorials as easy to follow as possible, all in a logical order. There will always be room for improvement when aiming for perfection! But we hope to always reach a good compromise.
best rhino tutorial i came across since i first learned rhino almost 8 years ago.
best rhino tutorial for surface developing. Thank you!
Hi Phil, these videos are great! I find I always find something useful in your videos. Very high quality modeling as well, really good!
Cheers Mark :)
Hi Phil, thank you very much for the tutoriols. They are very helpful. Can you make some more complex model's tutoriols too?
Hi there, we'll be making and posting new tutorials in the coming months, hopefully there will be something more complex available for you later in 2018. Thanks for watching!
Thank you! Still watching in 2021!
Thanks, happydrawing - happy new year!
pls give pdf for practise

really good tutorial :)
I'd like to know when and why do you prefer blend edges over fillet edges and vice versa. TY.
Hi Fabrizio. Thank you for your question. Blend Edge can be thought of as being an aesthetic improvement over Fillet Edge.

With the Environment Map or Zebra you can usually see a stop/start condition at the edges of a Fillet (this the effect of two different radii meeting at a tangent) whereas the Blend should look seamless.

@@SimplyRhino3D Thank you so much for your exhaustive answer :)

Thanks Phil... Will we see part 3 before Christmas?.. or perhaps a Boxing day release?
Hi Sean, the third part of this trilogy will be published in January 2017 - our New Year present to you! :)
Hey Phil! Excellent Tutorial! I have a general question, is this considered a parametrical modeling?
Thanks for your comments. This procedure isn’t regarded as being parametric modelling.

Yes!!! Thank you so much for your help!
Hi Phil
At 29:51. Why did you correct the negative curvature? Why it matters? Should we always avoid this?
Hi, I corrected the negative curvature as from an aesthetic point of view I preferred the curvature to be completely positive (convex). It’s a personal preference though - no other technical reason. Thanks, Phil.
