Bridge command SubD

.hi
thanks
the list of useful cammand for subd and mesh is:
1-tickness for subd
2-knife
3-symmetry(radial and planer)
4-collaps
5-weld
6-selection type methods
7’-connect {face and edge by curve path}
8-slice
9-bevel
10-sweep2
11_insert edge and face
12-rail revolve
13-organi pipe
and pleeas all the list of cammand subd for grasshopper

Thanks for the suggestions of Bridge enhancements.

  • Alignment adjustment is possible now using the handles during the preview

  • Divisions across the Bridge is possible now using the segments option

Did I miss anything?

Rhino’s SubD commands should look to those of Tspline, primarily, and also to Clayoo.
Not to copy, to imitate, but as a reference, since these very powerful plug-ins have been developed before and have had the time to mature and be consolidated.
I’m sure that little by little the Rhino SubD tools will improve, it seems to me that the starting base is good, but still, very, very incomplete, a little primitive.

Filed as InsertPoint support for subd https://mcneel.myjetbrains.com/youtrack/issue/RH-53954 an alias called Knife may be needed here (I asked for the same initially) but I think the functionality will be the same. Try it on a mesh now to test. Subd edges have mid snaps too which differs from mesh edges currently so it will be easy to cut the face evenly once InsertPoint works on subd.

Filed as https://mcneel.myjetbrains.com/youtrack/issue/RH-53823 for planar, I’ll add your vote for radial as well.

Can you give me some more info on what you want here? Look at CollapseMeshVertex and CollapseMeshEdge on meshes now. Is this what you want on a subd? It tends to make lots of tris which is why I’m asking. Also see if Ctrl + Shift select / sub-object select > Delete of subd verts and edges is of use for comparison to a traditional collapse in mesh modeling. I’ll file what we need but want to make sure I get it right.

Weld works on subd edges and verts now using WeldEdge or RemoveCrease which is on the Subd toolbar. The counterparts would be UnweldEdge or Crease. I think this is what you want, let me know if not.

Does the Filter menu > sub-objects let you do what you’re after? Also try the Named Selections panel to save selections of faces, edges, ctrl pts etc.

I think this is the guide curve Bridge enhancement but also see the present method using sweeps above.

I think you’re looking for subd Split support essentially with a Slice tool. I filed https://mcneel.myjetbrains.com/youtrack/issue/RH-54108

Filed as https://mcneel.myjetbrains.com/youtrack/issue/RH-49860 for InsertEdge subd support and https://mcneel.myjetbrains.com/youtrack/issue/RH-51194 for sub-object subdivision. You can also try Inset now on a subd face for adding one face in the center on another.

Filed as https://mcneel.myjetbrains.com/youtrack/issue/RH-54110 . Use a sub-d friendly curve (option in Curve command) and then ToSubd on the result of RailRevolve ought to work in the meantime.

Pipe has subd support already, if you mean multiple pipe intersections this is something that is being discussed and experimented with. You can use the Dendro add-on for GH now to make voxels and then QuadRemesh that to get to subd.

There are some components now for making subd from mesh or extracting the control polygon from a subd to get a mesh. Not a lot else right now but I’m sure more will come. FYI @DavidRutten

If possible, can you please make separate posts about individual features you need or want changed? This will help developers make sense of the thread and understand the key points when they reference the discussion later. Thanks!

A post was split to a new topic: Collapse tool request

@BrianJ Brian, two comments here:

1A. Is it possible to make this tool history-enabled? it would be very useful to live edit the outside surface of something and seeing how/when you reach the clearance you need with internal components of a product.

1B. Can we also allow SubD object to have that thickened sharing trick? BTW… MAJOR BUG: that whole row of buttons of properties for objects (thicken/dimensions/edge-softening…) is gone in this week build:

I wish to see the Bridge on SubD like Modo.

Bridge on Modo.

Hi
Please enable bridge face after executing the bridge command by selecting face or edge option

I know you added this feature, but please enable it after running the command for better results

The use of guide curves with Bridge is still on file as a request and currently set for 7.x which means it would not be in 7.0. https://mcneel.myjetbrains.com/youtrack/issue/RH-54107

Are you asking that the option to add guide curves be available when in the middle of running Bridge?

No, I didn’t mean to execute the bridge face command as we would after the bridge command
Not before executing the command

Thanks, I get it now and see the same… filed as https://mcneel.myjetbrains.com/youtrack/issue/RH-57203

On The Mac, while the Bridge controller dialogue is open, the viewport manipulation is frozen, [at least when used with 3DConnexion] .
So for example, if one started the command when the geometry is in closeup in order to correctly selects the edges, it is difficult to see the bridge desired shape without the ability to zoom out and perhaps rotate the view for a better angle.

Thanks a lot

This appears to be due to the 3D Connexion device needing focus on the viewport not the dialog during Bridge. Click in the viewport and it will work again. I think it is something we should be able to fix… this doesn’t happen with the BlendSrf dialog for instance. Filed as https://mcneel.myjetbrains.com/youtrack/issue/RH-57410
