Sliding SubD is maddening!

This kind of crap happens all the time!

slide-grr

Why can’t it be relative to the mouse cursor? I don’t care about the control mesh if I haven’t toggled it on.

Most of the time I just give up and just the mouse to view drag (which is also equally infuriating because it requires a second click… small things like this add up, which is why I prefer editing Subd in Blender instead where I just click once, press g-g and then I’m done).

Also, I keep having to press D-Enter to switch directions (while again, togglig the control mesh is a single Tab press like it should be).

Hmm this used to drive me crazy and I’ve left subd alone but I just tried now and it seems to be smoother? Although no - it still jumps around near the ends as if there’s a SNAP that isn’t being disabled.

It shows up the most when there’s an angle to the subD control mesh, not when its straight like you have. Also, I’m tilting the camera so the wonkiness of the line gets more pronounced AND I’m disabling snap (by holding Alt) in the middle of my video but you can’t really tell from the behavior or Rhino.

Blender does this 1000x better and faster (right now, I’m exporting OBJ files between Rhino and Blender several times per day). :sweat:

for sliding of a single point, i use box-mode and
_scale

Hi @eobet ,

Sorry this is frustrating in Rhino. I’ve filed https://mcneel.myjetbrains.com/youtrack/issue/RH-84594 and added this thread to it as well. Hopefully we can make it better soon.

Another thing that drives me upp the wall with Subd slide is that you might have to change Across/Along per vertex, which I just can’t fathom at all:

:confounded:

We hear you but I think you will enjoy more your work and how you use Rhino if you treat SubD and Rendering in Rhino as ‘barely better than having nothing at all’, and have no expectations of those tools to be any good. Especially if you are used to the tools/capabilities/feel/performance of Blender.

I gave up on Rhino SubD modeling a long time ago; it’s only limitedly useful for a quick edit of a few points/edges here and there, from SubD models modeled elsewhere. Even that limiting editing does need to have things like sliding working flawlessly and it’s not even close.

This, 3 years ago, I think was my last assessment of SubD in Rhino after fighting with a model and spending 2+ hours doing something that should have taken me minutes: Friction in SubD continues, all so unresolved, so slow, so frustrating

Today, I wanted to do a very small/quick thing: I couldn’t because we still cannot even use bridge with a mismatched number of edges on each side:

This is why all I want is a live link Blender <> Rhino where I can use both tools for what each is best. Maybe in another 3 years we see something in this direction?

Blender just adds a triangle where it works best?

Hey, since the T-splines patent has expired, guess what Rhino could do that would be better. :wink:

Yes. That’s standard practice in all subD/polygon modelers.

I rather see that sunsetting with the patents. It wasn’t very good.

always do slides in box mode. (and bevels, and insert edges, etc)

I say it constantly in my videos-

“model in box mode, refine and evaluate in smooth mode”

agreed that’s frustrating, but you can add that option to the button (say right click for across, left button for along) if you want, or hot key a version with along/ across as per your needs.

But you do realize that Rhino doesn’t telegraph this at all, so what you are proposing is still a click, a wasted mouse move, and a second really unnecessary click and another mouse move for potentially every other Subd vertex you are editing? That adds up.

It does not telegraph it because the tool does not have this feature by default, but you can easily customize any tool in rhino by adding command line options

for instance in this case-

if you add
-slide pause direction=across

to the left click button you get slide across

if you add
-slide pause direction=along

to the left click button you get along.

the option is sticky between operations so if you pick along once, you’ll get5 along the next time you choose slide. if you pick across, you’ll get across the next time.

see below-

hope that eases the pain a bit… :wink:
