Thanks Hovnan, glad you found our video useful.

Thanks for your comments, Andrey.

Good luck!

Hi Jonathan, Thank you for your comments. Many modellers use the technique of creating a second surface with a different topology purely to do the flow/orient etc which then becomes redundant after the orient process. Very often the cleanest and most efficient way of modelling a surface is at odds with the topology required for panelling/flow/orient. Another way of tackling this issue would be to look at a Grasshopper routine.

Simply Rhino - Rhino3d Video Tutorials ‘add odds with the topology required’ yes this is exactly right. Case in point with the shield example (if there wasn’t a logical way to just trim away). Then the dilemma becomes how to construct this surface and in a clean way with even topo.

Hi, thanks for your question and positive comments. Developing or flattening a double curvature surface always involves an element of approximation. There are some third party plug-ins for Rhino that may provide a better workflow and easier to understand inputs, but underneath the hood they tend to use similar calculation methods. Hope this helps.

Hi. When you offset a curve (or surface) in most NURBS based software including Rhino you will often generate a curve with more control points than the original. Offsetting at Rhino’s default setting is carried out to an ‘Absolute Tolerance’. If you are, for example, using a ‘Small Objects Millimetres’ template then this ‘Absolute Tolerance’ setting is 0.001mm. So, what happens when you offset is that in order to keep the offset within 0.001mm of the original curve then control points are added. In the command line options for Offset you can set a slacker tolerance for the offset (for example 0.05) which will reduce the number of points. If you want to maintain the original number of control points you can use the ‘Loose’ option from the command line. You will see that this may make the offset more inaccurate. As a compromise you could Offset at the default settings then lock the offset curve to use this as a ‘target’. Then offset with the ‘Loose’ option - you can then adjust the intermediate points of the ‘Loose’ offset to better fit the locked curve. It’s important to note that an ‘Absolute Tolerance’ is used for splitting, trimming, joining, offsetting and projecting and pulling curves amongst others.

@@SimplyRhino3D Thank you very much for the detailed explanation.

@@giyinikvatandas You're welcome, hope it was helpful.

Hi Spiro, I did this just to visualise the rectangular UV structure - it’s not a necessary part of the developing or flattening process. Thanks, Phil

Thanks Adan!

Thanks, and you're welcome, glad you found it useful. We find that many of our customers report that the ‘Magic Mouse’ supplied by Apple with the desktop Macs is not suitable for CAD and modelling - therefore a conventional wireless two button mouse with scroll wheel may be much more useful. Hope that helps.

Hi DC, Try ‘Smash’. If you have something like a 100mm solid box, shell it out to a thickness of 10mm from one face and then run ‘Smash’ then all the faces will be flattened and presented in ‘Top’ viewport. Look at the Options in the command line to fine-tune. Hope that helps - Phil.

Hi Happydrawing. In ‘Properties’ I set the object colours of the surface and curves to a custom colour (ie by object not by layer) and when I unrolled I used the ‘Keep Properties’ option - I didn’t make this clear in the video.

Hi, the command you are looking for is OffsetSrf with the Solid Option turned on. So, take your single surface frisbee go to the Solid Menu and run Offset and you’ll see command line input options for thickness, offset direction etc. Hope this helps.

@@SimplyRhino3D THANK YOU so much!

Hi Pedro, unfortunately not - using the Shrink command would give you a smaller rectangular surface but still one with four straight sides. You could get around the issue by using two lines and two curves to create the surface and use a command like Sweep 2 or Edge Curves to build a planar surface that had two curved (rather than linear) and two straight boundaries.

Hi Richard. I used the Iscocurve direction to help to explain how the rectangular nature of the surface behaves when it is unrolled (flat) versus the three dimensional shape. The Iscocurves themselves do not display on the flattened surface when it is unrolled and so I created curves from the Isocurves so that these can be visualised on the flattened surface. Hope this helps.

This video is an Introduction to the specific tools in Rhino related to Developing & Flattening Surfaces. From your comment it seems you are looking for a general introduction to modelling with Rhino, they are many other videos that cover that.

@@SimplyRhino3D Thanks for the answer!
