Really nice addition.
Maybe worth the option to create a point geometry in the position of Max deviation for later consideration such adding a knot.
I would add a new knot only if raising the degree by 1-2-3 steps does not help. Knots add unwanted indentarion of the shape. In the past I used to add more knots. Now I raise the degree.
Adding a knot at the max deviation point makes no sense, the knot might have to be added completely somewhere else for the most reduction.
Youâre right but not all the time you need A-class modeling.
For 3D prints,you better to be fast than smooth. I need to recostruct imported file, especcially when they come from SWks, and Iâve to make them watertight without spending days.
Inserting a knot using InsertKnot does not change the shape of the surface. (Inserting a control point using InsertControlPoint does change the shape.) After the knot is inserted control points can be moved, either directly or using a tool such as MatchSrf, to modify the shape of the surface as desired.
Inserting a knot allows for more local refinement of the shape.
In aware of this, but 99% of the time extra knots are used to add local detail, followed by control point âmassagingâ or matching the surface. Both operations distort the surface and lead to an unwanted indentarion where the extra knots are located. 
This is why I no longer do that and always try to refine a surgace by raising its degree instead.
Nobody with their mind is adding extra knots without an intention to modify the surface at the very area that was overly-crowded by knots.
Will GEC in rhino 9 be scrptable?
I wish to analyse a big file by layer /or by object-
and ideally would get a log file or report- will somrthing like this be possible?
I will look into whatâs possible. Note that GlobalEdgeContinuity is built on RhinoCommon. All the analysis functions that I am using are availbale, so you can analyze surfaces already with scripting if you need to.
In the latest Rhino WIP edge analysis updates live while making edits to your surfaces. This should make it much easier to tune in a surface to G1 or G2, especially on multiple edges at once. If you are using the new UVN gumball, tuning G1 on two opposite edges with a single control point becomes possible.
One thing that I canât understand is why the âGECâ refuses to analyze adjacent edges that are about 0,8 mm apart. I tried many different settings in the filter, but I could not find a way to activate the analysis. It happened on several pairs already.
On the other hand, the regular âEdge continuityâ tool is capable of showing these distance deviations even if the gap is much greater.
