3d sketching in rhino? check it out

I’ll wait… got excited to try the new.

in the mean time 2 notes;
it seems that while the fancy curves is on, the command prompt is disabled, so activating Sketch is only possible from the Manu [of the the tool icon]

the other thing, [maybe it is planed already ]. to make the line thickness also controlled by pen pressure. the way drawing with a brush works in various Apps.

thanks a lot

keep in mind these are not raster strokes, they are nurbs curves. the fancy curve settings are global atm and will be the same for each curve. It may not be possible to have multi thicknesses added to the curves, or have the taper be affected by pen pressure. This is all super new and may go somewhere,. and may not. We’ll see how people like it and if it’s useful.

Thanks for the video, is very nice. and fun to watch .

I was imagining [guess incorrectly] that a sort of a visual combination is used…? in which a regular Nurbs curve is overlaid with a raster stroke.

As indicated above, we never reference other companies software for our development. We reference you, our users. Other companies have solved their users problems, we are only interested in solving yours.

Hi -

You run the command to enable the feature and change settings and then end the command. You should be able to see this effect when you change the halo setting - that part seems to work fine on the Mac.
-wim

thanks @wim
I’m not seeing the Halo affect here… of perhaps I do not understand what it is…?

The fancy curves progress will be great, but improving the Sketch command [from my perspective as a jewellery designer] even just in the visually limited look of bare rhino curves. Will add important value when developing jewellery design.

I tried to several times to use Sketch in the past, ending up quickly dropping it in frustration.
Making the curves more controllable directly with the pen, seems to me the most urgent need.

@theoutside
Would you kindly explain why are you setting the pen tip to Right click? Here Sketching works correctly with the tip at default regular Click, [Right click with pan the view]

thanks a lot
Akash

Hi Akash -

It draws a halo around curves and edges when they are selected:

This does not work when you have TestMetal enabled.
-wim

if your set up works, then go for it- There are a lot of variations in different Wacom control panels depending on what driver you are using.

I had to make a profile just for rhino and set the pen tip to right click to get what I wanted out of sketch.

You do you- :slight_smile:

Next week’s WIP will support TestFancyCurves on Mac + Metal

Hi
it doesn’t work… Or I’m, doing something wrong.
No problem, I’ll wait for next week update.
thanks a lot

Hi Kyle,
Super interesting. Thanks for this.
I am also on a big Cintiq and I can’t for the life of me see how Right click on the tip would work. Left click for the tip works great for me. Horses for courses I suppose :wink:

Thanks and keep up the great work

Hello! Very nice feature!
Just an idea: it would be very helpful if the cplane on which is drawn could be moved real quick. It’s better to already draw where the stroke belongs, instead of placing it on yz and move it afterwards, right?
Maybe a slider on the side somewhere in the perspective view.
Or maybe there’s a second type of cplane just for the sketch tool, which has handles at the corners for quickly shifting it back and forth.
This new sketch-cplane could also have an auto-align-mode which flips it to xy/xz/yz depending on the viewport angle (as seen in Modo).
Thoughts?

hi everyone
i have 3 suggestions for this commands (testfancycurves)
A-SubD and Mesh Also suport wirefram an isocurve by SketchLine

B-TaperPosition Receive two quantities, for the beginning and the end
end size


C-add Line Extended similar to sketchy Style in AutoCad

Okay having watched your full breakdown video Kyle… this is really cool. I like the ‘Halo’ as a display thing anyway for a start, that could totally make it in without the line tapers for me just as something that would probably be easier to see and work with on a daily basis.

I’d be tempted to just say keep it up… plus:

  • ZBuffer needs to just have a control for the min/max. Someone did a plugin IIRC with a slider, that should just be default rather than hidden away somewhere. When you showed the ZBuffer trick too occlude some of your sketch, I was genuinely really impressed. A great thought. See below:
    Better use of viewport ZBuffer functionality please - #11 by Mahdiyar

  • The undo stuff you mentioned within the command, seems a no brainer in a SketchMultiple, or something.

  • Fancy Lines by layer?

  • Then it seems like it would be a case of having shortcuts and highly interactive CPlane stuff. The Cplane ‘Elevation’ is a very useful command as an example, where you could quickly go from World Right >> to something in line with one of your wheels. A crazy off the bat idea would be something like, a CPlane which locks to be in front of the view, and you can visualise how ‘deep’ / far away it is by everything behind it being a certain colour, or transparency.

  • There’s that old CurveOnSurface plugin isn’t there. Could this ‘Sketch’ focus be something that brings Curve on Surface tools back the fore? This is something that is critical in footwear - the idea of a lightweight, easy to control curve with very few points, which is pulled (behind the scenes) to a complex surface. Make sense?

Hi @theoutside ,
I actually did that bit of mish mosh in the 3d perspective viewport using the sketch command. I haven’t tried v8 yet waiting until I get a new box for that.

I like the echopppe/burin type line work that Steve is inventing. I did a lot of engraving and etching and the one thing that repells me from all computer drawing is that there is a disjunct in drawing compared to the real world sketching. But it’s a different paradigm.
Like what you’re doing with this and hoping it evolves.

This should be a standard feature. Not only for sketching.

Don’t know if you were already aware of it, but it also seems to work with the iPad as a secondary screen and the Pencil as an input. Haven´t had the time yet to properly try it out, but here is a first quick coffee mug test haha
The pinch to zoom gesture works, would be very interesting if rotating the view with gestures would also be possible…

Cool!

This new sketch-cplane could also have an auto-align-mode which flips it to xy/xz/yz depending on the viewport angle<<

have you tried oneview?

Agreed cplane input will be important to get this right. The current options, (cplane to view, 3 pt cplane and set cplane origin seem to be working well here, I’d be curious to know what options we are missing in the current tools.

start with regular 2d sketching and then start rotating, moving and adjusting your curves to get 3d curves.

This is new to all of us, so experiment and try it!

Wow, just discovered - love it!

Would an option to derive the TaperThickness and/or the TaperPosition from the curves curvature be of interest?

Currently the FancyCurves parameters are global. Are the intentions to keep them global or is there a chance they may become parameters per Curve instance? If they may become an instance per Curve, it would be nice if the setting of the parameters can be done through GrassHopper.

Taper position examples:


TaperPosition=0.5 (current functionality)


TaperPosition=Curvature (derived from Curvature)
