Boost your productivity with a 3d mouse (part 2)
1. The 3d mouse offers a much better and smoother camera navigation around the objects. Its advantage is especially noticeable in tight areas and close-up examination of the models.
2. The biggest advantage is the huge relief for the right hand, because the latter no longer needs to do extra movements for the camera rotation, panning and zooming.
3. You can also move the camera with the 3d mouse while doing something else with the regular mouse, even if pop-up windows are active.

Fixing a warped area caused by the "Fit" tool
Переглядів 148День тому
The "Fit" tool in Rhino tends to cause warping in areas where the curvature of a surface suddenly changes direction. Such like the middle of surfaces shaped like the letter "S". It's a common problem in NURBS surfacing which the automatic tools may not fix automatically, hence the need for an additional manual adjustment.

Bug with OffsetSrf
Переглядів 45121 день тому
For some reason, when I offset the surface with History recording, then create another offset (this time as a solid), Rhino decides to create and offset of the offset, resulting in a 3 times thicker model than the intended shape, plus fillets. If I delete the history of the initial offset surface (the top one), then the solid model created afterwards is proper.

That's the added benefit of watching the entire video. :) Navigation in Google Earth Pro is extremely natural with the right settings of the 3d mouse. My internet connection was too slow while I captured the video, so the streaming of the 3d geometry was slightly delayed.

Why don't you overwrite the video with the most significant command you are using? This could be very great to help me to understand

Indeed! One of the many great fan-made tools for Rhino.
Thanks for another great modeling video! At 16:30, the continuities of distance and tangent were out of tolerance and you let it be . Can you extrapolate that more? Thank you. I'm always snaped with not good enough continuity values and couldn't overlook it.
Thanks! With regards to your question, I don't see anything to worry about. The angle deviation is just 0,07 degrees, which is more than enough for manufacturing purposes. The "Tangent tolerance" setting in the "Edge continuity" panel is just for visual purposes, which means that any angle smaller than 0,01 degrees will be marked in white, anything greater than 0,01 mm will be marked in red, and the blue colour shows the area of maximum deviation. In Alias Automotive, for example, a good continuity is considered anything less than 0,1 degrees. Even professional car designs have up to 0,1 degree of deviation, but finished steel moulds and stamping dies are manually polished and all the deviation is fixed by hand. :)
@@AutomotiveCNC I see. You reminded me of what you had said on the Mcneel forum: '...flawed model is still good enough for manufacturing.'
@@kuoyihsin , it all depends on the size and shape of the model, as well as the material used for the manufacturing. I often deal with CAD models from suppliers of car parts (mainly created in Solidworks) and I can say that almost all of them have quite a lot of flaws. Eventually, these flaws are fixed by hand in the real life. :)
Thank you !

I am a professional digital marketer and SEO expert. I saw your AutomotiveCNC channel, And your channel content is very good. But video views are not good. Your channel has some issues due to which your videos are not getting good views. The main problem is SEO. For which your channel video views are not increasing.
Congratulations for your videos. I also encountered several problems with this command from a polysurface without any errors after careful analysis tests, then after using _offsetsrf (20 errors that were not there and the surfaces sectioned), direction 0.20 as tolerance between male and female, _RebuildEdges didn't improve things either. Is there another method to give a tolerance of a few 0.10 mm for example? Ciao Thanks
Applying offset to Polysurfaces usually cause problems, because upon creation Rhino used the file's tolerance to join the individual surfaces into a single polysurface. Depending on the offset distance and direction, this may lead to bad objects, because the joined edges are scaled into another size, hence the distance between them changes accordingly. The risk of potential error increases in areas where two surfaces are not perfectly tangent. Imagine that the file tolerance is 0,1 mm and, there is 1 degree deviation of the tangency between two flat surface (meaning there is a very difficult to notice 1 degree crease), and the offset distance is 100 mm. If those were separate surfaces, there would be a gap of approximately 1,7453071 millimeters between their adjacent edges. However, if the input surfaces are joined together, the resulting offset polysurface will have to rebuild each surface internally, in order to fill the aforementioned gap. while this is easy with flat surfaces, the rebuilding gets more complicated on curved surfaces joined together. This is the biggest reason for producing bad objects and open seams after using the "OffsetSrf" command.

This is fun, but shouldn’t you avoid modeling two edges which meet at a single point at the same tangency due to potential tolerance errors?
Since I match the second blend surface with the "OnSurface" option (for example, at the 16:53 minute), this is not an issue. Once I achieve the desired tangency, I use the edges of the matched surface to split the target surfaces (21:17 minute and 34:45 minute). This is opposite of what most Rhino users do when they use "Match surface", which has the "OnSurface" option turned off by default. The advantage of using "OnSurface" is that it typically add fewer extra spans and control points to the matched surface. Sometimes, it will not add extra spans and control points at all.
I have an issue, can I cut a half of object and mirror to other side?
Yes, you can. Depends on the type of object you want to mirror.

I'd be happy to buy you a BUNCH of coffees for that . In fact, there is a dirth of really good advanced Rhino tutorials on line. I think people would be happy to join your channel and PAY for it.
Thanks! I always try to be creative with the mechanical parts I design. With regards to your question, this particular 3d model was made a while ago, so here I just modified a small portion of it. The whole process took a much longer time. Since it's a work done for a customer, initially I had no plans to capture the modeling from start to finish. In fact, some of my older videos show exactly what you are looking for, but some people said that they are boring to watch, because the modeling is slow and tedious. :) This sort of videos is direct modeling of components to be used in manufacturing for real projects, so they require patience and include plenty of trials and errors. Most people expect quick tutorials instead.
Sick job dude!

Ну ты понимаешь, что я хотел сказать , про параметрические CAD...
Да, к сожалению, Rhino не поддерживает параметрическую историю модели, поэтому любое изменение требует ручной работы, которая занимает много времени.
Great video. I enjoy watching proficeint 3d modelers like you. I know it would be more work, but it would be great to either have subtitles, audio dialog, or onscreen text explaining your process and why your doing certain steps. I'm somewhat proficient so I'm able to follow along for the most part, but I started to get lost when you were mirroring, rebuilding, and matching the surfaces over and over to again. Looking back at the video I understand why you were doing it, but it would be great to be able to follow along in the moment.
Thanks! Very nice and constructive opinion, by the way! I completely understand your point of view. Since "Blend surface" does not perform well with degree 1 input surfaces, I rebuilt the primary surfaces to single-span degree 5 with 6 control points, because that's the optimal geometry to build blend surfaces. The mirroring that followed the previous step was done to save time, because I already had rebuilt surfaces at one side, so I wanted to skip repeating the whole process on the opposite side. This also ensures that I work with a totally symmetrical geometry at either side. The same goes for the mirroring of the vertical cutting planes that I used to split the circular extrusion. 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. Usually I try to hover my mouse over icons for extra long time, in order to let my viewers see what I'm doing and understand the process. Many so-called "tutorials" on UA-cam use fast pacing and even professionals are unable to figure out what's going on on the screen. Note that this is a quick free tutorial made for a Rhino user on the Rhino forum who asked for tips about creating a pretty simple air duct adapted. I also create private video tutorials on demand with deeper explanation of every step.

Cool :) Can you explain what exactly you dislike about my willingness to share knowledge with the others? Your opinion can help me create better content in the future.
¿?
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?

Hi @AutomotiveCNC, Thank you for replying to my issue on the McNeel Forums. I'm the architecture student who was asking for someone help me with my round roof top.
I would be glad if this is of any help for you. I suggest to build entirely new walls of the house using blend curves at the corners to maintain G2 continuity. Once you have a clean geometry, making the roof will be much easier and it will look as smooth as possible. I will add such a 3d model to the topic where you made the request.

I thought that you will use pull curve command to pull the curve on surface to match it.
That would create a curve approximation with too many control points. A surface built from a pulled curve is also inaccurate and needs extra matching, which adds even more control points. The idea of the basic curve with 4 control points which I used is to create a simple surface with fewer control points, then match its left edge over the untrimmed target surface.
@@AutomotiveCNC In pull command, there is a loose option. If you change "loose" option to yes, it will not change the degree or point counts of curve. It will try to best match it to surface without changing curve.
@@akchemaceshwa , I'm aware of this, but using a manually adjusted basic curve is the better way to build the surface.
@@AutomotiveCNC That is how it works. But matching curve, surfaces to achieve desired continuity is also the part of the process.
@@akchemaceshwa , pulling a curve on surface uses the normal direction of the latter, which is a limiting factor. Manually adjusted curve is the better option, because the user has a full control over the shape, with no imitations.
Great work and very useful. There are very few tutorials for high level modeling in Rhino. If you want to make it clearer and help even more it would be very useful to use a cursor highlighter and a text label for each command you use . You have a pretty big display and for people watching is very hard to track mouse movements and keyboard commands. In case you don't already know it, I recommend ShareX
Thank you for the kind words! With regards to your suggestion, I use a 1080p size of the Rhino menus and scale them at 200% in the Windows 10 settings, in order to get a 4K output. This means that the icons and toolbars are equal to what a basic 1080p monitor will output. As for the mouse movements, I purposely make them slowly and hover over the icons for a moment, so that the viewers could easily see the mouse pointer and the name of each command. I record my videos with the integrated video recording chip in my Nvidia graphics card through the "Shadow play" panel. It does not support highlighting of the mouse cursor, however.

so, seems like it works at the opposite of sweep 2 rails, you have to select first the curve and then the "two rails"
Exactly. It will accept 3 input edges only in case that the first picked edge is the middle one. Sort of what the "Sweep 2 rails" tool uses as a rail. This seems against any logic, but it is what it is.
If i Recall correctly this happened in rhino7 aswell. Because when i started in rhino7 i thought this function is similar to icem surfs Patch command. Generating Patches from 2,3 or 4 curves. But i never Got IT to Work in rhino for three sided
The tool works on 3-sided input edges only if you pick the middle edge first, then the remaining side edges. :)
