T-Splines 3.3 beta

[Matt Sederberg]

We're excited to make available a beta release of T-Splines 3.3 for Rhino.

Check out the November 29th webinar with Sky Greenawalt where he introduced how he is already using these tools to convert scanned aircraft parts into machinable surfaces.

If you have a license of T-Splines v3 for Rhino, you can download this and try it out. Please share your feedback with us about any bugs, Rhino 5 compatibility issues, polish requests, etc.

Click here for the latest 3.3 download.

New features:
Retopology snap (icon is in the edit mode heads up display). When this is on, then T-Splines grips will snap to the closest object in the scene.
The follow commands respond to retopology snap: moving vertices/edges/faces with the manipulator. tsAppend, tsExtrude, tsInsertEdge, tsSubdivideFace, tsInsertPoint, tsSlide
tsAppend is greatly improved with new options and behavior
New tsBevel tool
tsInsertEdge has a new option to let you specify an exact distance (along the control polygon) where the new edge will be inserted.
New tsSlide command lets you slide edges along the control polygon
The manipulator SetPivot now allows you to set the orientation of the manipulator along with its position
New selection commands: Select next loop, previous loop, Next U, Next V
New tsUVEditor command
T-Splines now works with Rhino’s CageEdit command
tsSkin completely rewritten
tsLoft completely rewritten
The Edit mode HUD now shows more icons and is docked by default.
The old v2 transluscent box HUD has been updated to work with new v3 items and is now called Text Viewport HUD.
When tsExtruding a face or an edge, you no longer need to undo twice to undo the movement and the extrusion. Just undo once! Note: when you extrude a curve, you will need to still undo twice.
tsSymmetry has more clear command line prompts
tsInsertPoint has more consistent selection
tsPipe has new diamond joints
tsPull now properly moves tangency handles when it moves vertices
tsBridge now has the proper handles to let you change the twist and direction of the bridge
New tsExtractEdges command

Known issues in the beta, which will be fixed before the final release:
The option in tsMatch to match to curves is currently broken
CageEdit integration is not working very well
tsSlide will not move all edges in the same direction when one end of the selection is a star point

Happy Thanksgiving!

WOW!

[v2122]

Thanks Matt!!

Good news!

[HaLoe]

Thank you!

Been really looking forward to the exact distance option in tsInsertEdge.

[laborda]

Thanks a lot for all the enhancements!

[Matt Sederberg]

Note: we've just updated the beta with a new version with some fixed bugs, more polish, etc. The download links at the start of this post are now for the new beta (version 7883).

Please let us know if you find any bugs, have polish requests, etc.

Thanks!

[fredrik]

Seems like the download link is broken?

I want to try it too!

[knead]

Matt! "Page not found"

[Matt Sederberg]

Sorry, should have tested that link last night. For some reason version 7883 didn't make it online. I've changed the link at the top of the page to version 7879, which was an internal release a few hours before. This should still be an improvement over the first beta. We're a little less organized than usual since it's Thanksgiving morning . Gotta go figure out how we're going to cook our second turkey! (We're feeding 20 people today).

Thanks!
Matt

[Matt Sederberg]

Ok, version 7833 is now online, and if you download at the top of the thread, this is the version you will download. Thanks for your patience.

[fredrik]

super!

How about using 3.3 beta alongside 3.2?
Will 3.2. be overwritten - or do we have to choose which version is loaded into rhino?

Ciao, Norbert

[Matt Sederberg]

Norbert,

You can only have one installed at once. However, if you install 3.3, you can later uninstall it and reinstall 3.2 (which you can get at tsplines.com/latestversion)

Alternatively, if you are using Rhino 5 64 bit, you can install tsplines 3.3 beta there and leave 3.2 installed on Rhino 4.

hi,

Great improvements!

One question, any chance to get the Retopology snap to work with the on-surface control vertices?

Real hard to get a snug fit otherwise.

[Matt Sederberg]

Very good point Bjorn.

Sky will be talking about strategies for this in his webinar today.

A few suggestions:

1. After you have the surface laid out in box mode with the vertices snapped, run the tsInterpolate command. This will recalculate the surface so that it passes through the vertices.

2. You could also just subdivide all faces with retopo snap on a few times. This will greatly improve the fit.

But tune in today if you can and Sky will talk about this in detail.

Hi,

I try to check out the video version of the podcast afterwards. Don't have time today I'm afraid.

But won't both these suggestions increase the comlexity of my tspline? (ie. add points)

Is it hard technically to make it work with the on-surface vertices/points of the tpline?

regards

- björn

[Matt Sederberg]

Bjorn, tsInterpolate will not add additional points. I agree that getting surface points working with this would be a boon.

[Nicholas North]

Björn,

Surface points are not "real" points. When you move a surface point, what is actually happening is multiple real control points are moved so that the surface point gets positioned where requested.

This poses a problem for Retopology snap. If you were to snap a surface point using Retopology snapping, a bunch of real control points have to be moved, but this alters any neighboring surface points (which also rely on some of the same real control points). So we have to know which points need to stay and which can move. For example, we can snap all the surface points you currently have selected, but any unselected surface points nearby will then have to be moved when snapping the selected ones. This keeps you from being able to accurately snap a subset of surface points, as doing so would always mess up work you already did.

tsInterpolate solves all surface points simultaneously, avoiding the problem I tried to describe above. As Matt pointed out, it doesn't add any new control points. It just moves the ones you have.

Great webinar last night can't wait to get started this morning to have a go.

Just one question when I load up 3.3 I see the Retopo snap in the HUD but my toolbar is the 3.2 version without the new commands.

Cheers

[Joe]

We have had several report of this and we are looking into it. We'll let you know what we find. In the meantime, you can either go into T-Splines UI in the Rhino options and check "Retopology Snap Options" or you can get to the Retopo options by entering the command "-EditMode" and clicking on "Retopo."

[Nicholas North]

We have just updated the beta with a new version 7925.

This version fixes bugs and continues to polish features. The download links at the start of this thread has been updated.

Please let us know if you find any bugs.

Thanks!

Hi everyone..

Looks like the english tool bar has not been updated (new 3.3)... I dont get the same icons in the french tool bar than in the english, missing the uv in the english and other retopo..

Thanks

Jennifer

[swisscad]

hi again..
an other bug maybe...
Slide edge does not work with symetry on... If you slide one edge on one leg et doesnt update on the other side.. but it does not crash or cancel symetry

[dodenko]

Why doesn't the rhino version have same functionality as solidworks one?
After you can convert to NURBS there is no way back unless you make a copy.
So please add some sort of feature like CREO,Catia have..

Shouldn't be hard...

I think You should post this request in the rhino newsgroup.

Hi again
found a way to get the new toolbar in..
I closed the tspline toolbar from the toolbar manager menu and went in the tspline menu utility...then load toolbar and... tada now its all ok

[oliviertij]

Hi all.

The last 3.3 is just wonderful... You might be very proud.
Retopo snap : woooh !

Thank you for this early Christmas gift.

[bjorn.syse]

Possible bug, after I've used "insert a point Simple", I get thrown out of Ts edit mode.

Yeah Bjorn, this is a known bug. I think it will be fixed in the next built.
Thanks for reporting!
