Using appropriate modeling techniques could lead to far better surface quality, and also reduce the modeling time and file size. It's a common practice in Class-A surface modeling to follow two main rules that are shown in this example: 1. Refit the majority of trimmed surfaces (wherever possible) so that they will no longer be trimmed, hence they will offer as clean edges as possible. That will eventually let the adjacent surfaces to be simpler, too; 2. Align the direction of the edges, in order to achieve a more natural flow of the reflections.
That's nice surface in the end, but... One thing I (as new Rhino user) can't understand why can't it properly Match Surface from the first round?! Even building from perfect curves, you get non-continuous surfaces and then you need to do 2-3 circles of Matching on every pair of edges, doing all that mumbo-jumbo with settings? Is that normal?
This is a nice question. The reason to make a series of "Match surface" operations is the limitation of the tool to produce flawless results from the first run. The "Match surface" tool actually can match up to 4 surface edges simultaneously, but it does it in a bit dirty way, meaning that in most cases at least 1 or 2 of the matched edges are still not perfectly matched. This is why I prefer to match the most important edges first (the ones on the left and right side), then match the less important ones (top and bottom), then match everything again, and again, until they are good enough for the purpose of modeling.
@@AutomotiveCNC Thanks for the answer. Another problem is that MatchSrf in Curvature mode ruins connected edges, so you match one edge, but damage other 2. I've noticed on your last Match on top edge you switched settings from Curvature to Tangent, but it still gave you decent curvature match. How does that work? I've tried repeating in Curvature mode, and... Even in 20 rounds it doesn't align perfectly, as it destroys neighbor edges. As I understand the only alternative way is using BlendSrf instead, or expensive 3rd party plugins like xNurbs?
@@nicktyler2572 , Rhino's "Match surface" has its shortcomings, so to solve the issue with inability to match to multiple surfaces and still maintain curvature continuity, usually I match the most important (larger) surface edges with G2, then I switch to G1 for the less important edges. I repeat that several times, because "Match surface" improves the continuity after each iteration. However, this must be done with care, because sometimes it may break the surface continuity and make it worse. Of course, you can further improve the curvature continuity via manual control point editing, but this is a really slow process.
Without reading the description its not easy to understand what you want to show. I rarely read the description before watching a video. I think most people do. Maybe you could edit the text in the video? It would also be easier for you to explain it this way if your not doing voice overs.
@@aloexkborn , thank you for the suggestion! I have never tried how text is added to videos. My video editing skills are practically zero. :) I simply record my screen and then upload. However, I may take a look to figure out how those text fields work. As for the voice over, I'm not sure if people from various nationalities will be able to understand while I speak Bulgarian language.

Nice work. I hope they provide more info on the Edge continuity tool.
Thank you! The Edge continuity tool is a really great addition to Rhino 7.

No audio?
With regards to the voice over, I'm not sure if people from various nationalities will be able to understand while I speak Bulgarian language. :)
Which rules?
The rules shown in the video above. Also, explained in the description.

@@AutomotiveCNC you can use AI for voices or subtitles
@@thiagordooo , can you suggest some tutorials and free AI programs that can do that?
