  1. Hello everyone I have a small collection of nodes that I took over from networks. Please test the function first and then install it in a network. Use at your own risk. Ungroup.vwx
  2. 1. I use the nurbs surfaces to be able to arrange a path. 2. The path spreads over the entire area. 3. The position values xyz / abc can be read out in the path. I master each of the three positions mentioned above as a single element with a marionette. At the moment I have to select each nurb surface individually, generate the path and then read out the position values. Now I want to connect the three elements. Ultimately, it is about creating a consistent automatism. At the moment I think that I can read the modification points from the individual nurbs curves and then create a nurbs surface. Marionette's list calculation will be useful for this. Unfortunately, this is a detour. Thank you for the many responses and the interest you have shown. My text was translated in Google...
  3. Hi, everyone how do i use this node?
  4. @Pat Stanford Yes of course. I thought I didn't know the right knot. there is also the "Surface From Curves" node which I see as promising. Or "Set Closed 3D" for polygons, but I need a node for nurbscurves. many thanks for your help Volumen in Nurbs umwandeln.vwx
  5. Hello everyone At the moment I know the 3D model nurbs commands. I have created many nurbs curves with Marionette and I want to convert them to nurbs surfaces with Marionette. I think that the curves would have to be closed first. Which node do I have to use? Maybe there is a combination of different nodes? Thank you for your help. Have a nice day

    Hello everyone I now have a marionette with which I can determine the angle of inclination and the position in space. position xyz rotation abc In one of the two videos I subdivide lines with and without vertices. In the other video, the rotation around its own axis is shown. You can see in the video: blue, the position of the vectors red, the Vector green, the corresponding area The graphic representation is only intended for checking the results. I know the .xcs export format from Interiorcad. Can I also output this format from a spreadsheet? Bildschirmaufnahme 2022-11-08 um 20.45.28.mov Bildschirmaufnahme 2022-11-08 um 20.42.36.mov

  9. When I use the marionette directly as a box object, Vectorworks crashes. If I use the marionette in a macro as a box object, then I lose the flexibility of the box. Adjustments are only possible via the symbol of the marionette. The hole in the path object always has a diameter of 8mm and a depth of 12mm. How can I control them in the marionette? Thank you for your feedback signal.
  10. Hello Pat Stanford I want to be able to determine how to round. For example, in the image above, I want to round down to a whole number. In my opinion, the "round" knot is not suitable for all applications. I miss: 1.8=1.0 1.3=2 Especially when I split a route, I need whole numbers to continue working. The problem is that the individual sections must have a minimum or maximum size (smaller than and larger than). I still don't find my solution really good. Are there better variants? Abrunden.vwx
  11. Hello everyone I'm looking for an example of how to easily round in Marionette. I would like to determine whether to round up or down. a round of five would also be cool. who can help? Thanks and have a nice day

    Hallo Zusammen Nun zu der Matrix kann ich nicht mehr viel beitragen, das Thema scheint über meine Gehaltsstufe gewachsen zu sein. Anwendungsbeispiele nehme ich weiterhin gerne entgegen. Mit der Datei im Anhang finde ich meine Punkte im freien Raum. Dabei verwende ich jeweils einen fixen Startpunkt und einen veränderten Endpunkt. Betreffend Trigonometrie verwende ich meistens diese Seite https://www.matheretter.de/wiki/dreieck-berechnen-abc Zwei der drei Rotationen bekomme ich so hin. Wenn nun jemand die passende Mathematische Vorgehensweise liefert, dann benötige ich die Matrix nicht mehr. https://www.meccanismocomplesso.org/le-rotazioni-in-3d-e-gli-angoli-di-eulero-in-python/ Now I can't contribute much more to the matrix, the topic seems to have grown beyond my salary level. I am always happy to receive application examples. With the file attached I find my points in free space. I use a fixed starting point and a modified end point. Concerning trigonometry I mostly use this site I can do two of the three rotations that way. If someone now provides the appropriate mathematical procedure, then I no longer need the matrix.

    @DomC die angehängte Datei enthält einige meiner Gedanken. Momentan bin ich jedoch noch nicht soweit alles zu verstehen, was die jeweiligen Knoten anstellen. Bitte die Ebenen durchschauen, vielleicht ist etwas mit dabei. Ich denke, dass durch den Erhalt eines Vektors zweier Punkte der nächste Punkt mit einer Rotation errechnet werden könnte. Schlussendlich wäre eine lange Aneinanderreihung von Vorgängen notwendig. Daher möchte ich die Matrix richtig anwenden um direkt an den resultierenden Punkt zu gelangen. Dazu müsste allerdings ein definierter Abstand zwischen den Punkten in die Matrix mit einfliessen. Ich gehe davon aus, dass nebst der Matrix auch einige Trigonometrie Kenntnisse erforderlich sein werden. Vielleicht gibt es auch eine rein Vector basierte Lösung. Sicher ist nur, dass ich die Matrixknoten besser verstehen muss um damit arbeiten zu können. Daher die Frage nach Beispielen. https://de.wikipedia.org/wiki/Eulersche_Winkel https://en.wikipedia.org/wiki/File:Stress_transformation_3D.svg the attached file contains some of my thoughts. At the moment, however, I'm not ready to understand everything that the respective nodes do. Please look through the levels, maybe something is included. I think that by getting a vector of two points, the closest point could be computed with a rotation. Ultimately, a long sequence of processes would be necessary. So I want to use the matrix correctly to go directly to the resulting point. To do this, however, a defined distance between the points would have to be included in the matrix. I assume that in addition to the matrix, some knowledge of trigonometry will also be required. Perhaps there is also a purely Vector-based solution. The only thing that is certain is that I need to understand the matrix nodes better in order to be able to work with them. Hence the question of examples. @MullinRJ Den Punkt einer Drehung um die Achsen zy kann ich mit Trigonometrie errechnen. Eine Rotation um xyz Achse habe ich noch nicht geschaft. Ich denke, dass die Lösung bei den Matrixknoten ist. Schlussendlich geht es darum, einen Punkt im Raum mit bestimmten Neigungswinkel und Abständen zu finden. Stellen sie sicht ein sich drehendes Flugzeug im Sturtzflug vor. Sie sehen aus dem Kockpit und möchten wissen, wo sich die Flügelspitze befindet? --> Bild I can calculate the point of a rotation around the zy axis with trigonometry. I haven't done a rotation around the xyz axis yet. I think the solution is at the matrix nodes. Ultimately, it's about finding a point in space with a certain angle of inclination and distance. Imagine a spinning airplane in a nosedive. Looking out of the cockpit and want to know where the wing tip is? --> picture Gedanken zu Matrix.vwx

    Hello everyone I am trying to create a matrix. Who can show me with an example how the knot works? Thank you for your help
  15. I now find the points with trigonometry. https://www.matheretter.de/wiki/dreieck-berechnen-abc I still need the ring. Who has a simple solution ready?
