It’s switching the interaction method for rotation between a “aim at mouse” method and a “left-right sliding” method, depending on the camera viewing angle (at very flat angles the “aim at mouse” method doesn’t make sense anymore). The value is the angle where the switch happens.
Not sure why it’s called tangent, it could have to do with the left-right sliding method (length of displayed tangent=section length of the gizmo circle but not sure)
I feel like the future of 3d work will eventually be in portable mobile devices like tablet, there’s already godot an awesome 3D game engine ported to mobile but not yet supported on ios/ipadOs which is a bit sad. I could just do some modelling work in nomad, paint it , rig it and use it in the godot editor. That would be fun!
Yeah, the forger forum died a long time ago, but now I can’t even see it.
How do I access this? Can’t see it.
My forger is up to date
Do you have classic or the new forger app?
Tangent because you slide on the tangent,
See 3ds max gizmo preferences. It’s basically what they call « linear » I think.
And the alternative is called « circular crank ».
And their threshold is name « planar angle threshold ».
The circular method is a bit more intuitive, but it fails completely when viewing at some angle.
I haven’t tried 3d max but I would like an option to hide the gizmo altogether when modeling.
Have you tried transform tool with new functionality in Webdemo?
This is probably what you want.
Hiding the gizmo isn’t a good idea in a 3D environment. Everything is bound to arrows.
3ds Max has 2D views and you can lock movement to two axis only. That’s the moment a Gizmo can be less useful.
Specially in shape operations when you want to control a bezier ending in X and Y, but the gizmo is far away at connected vertice and Gizmos active axis is Y only. In this case you lock transform to X and Y and hide Gizmo to not limit to one axis only………if this is understandable explained ? 
What would be your user case for hiding the gizmo in Nomad?
I don’t like Subscription but 13 pounds a year is nothing, I tried Forger yesterday and it is weird in my opinion (without slicing, split tools I can’t see why someone would want to use Forger). Nomad is way more intuitive and to keep this app from Maxon, or any other companies hands, I would pay 14 a year for sure, as I have payed for a version on every single Tablet and Phone I have. The tube tool profile and extra control per node is the only thing I would like to see coming soon like in the post Knacki did this days!!!
Nomad doesn’t have poly modeling yet, so right now the gizmo is needed where it’s being used. If we get poly modeling I would like an option to hide it for that.
I found one way to make a simple cube work in symmetry but it doesn’t work with all the tools so I don’t think symmetry in poly modeling is a feature yet. It makes modeling not a useful feature for me in forger at the moment.
The subscription price really isn’t a deal breaker in my opinion, I just don’t like subscription based apps, the price however for the year at £12.99 or £1.79 for the month to me is not bad at all, it’s more tempting with this latest update and the tools added.
I’d like to add that I am not against say a developer adding additional features and uses to the app as a reasonable one time fee, features that can help really improve the apps use.
I like to Support single or small developers of apps and games, they are not constrained by the already watered down ideas of the bigger company’s and are more free to design away.
I don’t care how good they‘ll make Forger, with their subscription crap they lost me. Won’t upgrade even zbrush. Shame on Pixologic to sell to Maxon .
My friend used to work at Maxon… he‘s seen things you people wouldn’t believe and it’s not attack ship on fire off the shoulder of Orion.
Scumbags.
@ StefanJohnsson as cracky says, hiding is not a good idea, but and the maxon know that a scalable gizmo is the way to go. i used to use c4d from maxon a lot and with pleasure and there is the possibility to scale the gizmo, because otherwise it gets in the way when modeling in points mode.
What benefit do you get from the gizmo when modeling? Do you normally model with a pen or mouse? Do you want a gizmo when sculpting?
I understand the use if you want to rotate the angle of a face or move it in just one direction, but most of the time I model like I sculpt and I prefer the organic feel of no visual clutter. However, I don’t do this professionally or even that well so I’m probably doing it wrong.
Did you try the other transform tool in Webdemo, like I said?
That’s a 100% fit for you, promised.
You enter the transform tool
One finger moves the object, two finger scale the object.
If you tap with another finger on screen, you’ll swap to rotation.
One finger rotates around actual object axis, two finger rotate for full rotation, two finger pinch for scale in both modes.
With snap to move on another object surface. 
If you don’t need that precision, as you said, you won’t use the gizmo tool anymore.
My point exactly!
I have be trying it. I can seem to get single tap to switch mode to work. Not sure what I’m doing wrong. It looks like a nice option for transform.
Webdemo does not support pencil + finger. You have to use both fingers for testing the fun.
