me of the dimensions that changed ( become Diagonal after they were Vertical or Horizontal)
I sometime use Record History in rhino for saving time, but when I change some points of curves or trim curves , I have problems with dimensions (see the two pictures below).
Problem 2 :
After trimming , only two dimensions should be changed depending on their place in changed curves . But what happens is that all the dimensions become crazy!!!!!!
I always use Aligned dimension in rhino. Now I know that dimensionsdo not exist in grasshopper. So I ask you if we have expertise in BV , C#, can we create a script for dimensions or is it impossible ??
If we can , I only need Aligned dimension.
I hope that I find or create a script that can define all points: start and end of curve ribs and create dimensions from grasshopper to rhino directly with or without the ability to change automatically .
Thank you

rtitions." (http://wias-berlin.de/software/index.jsp?id=TetGen&lang=1)
To continue with my wrapping career, TetRhino (or Tetrino) is a .NET wrapper for the well-known and pretty amazing TetGen mesh tetrahedralization program. It provides one new GH component for discretizing or remeshing objects using TetGen. Basic tetrahedralization functionality is exposed with a few different output types that can be controlled. At the moment, the only control for tetrahedra sizes is the minimum ratio, which is controlled by a slider. This is hardcoded to always be above 1.0-1.1, as it is very easy to generate a LOT of data (and crash)...
The libs are divided again into different modules to allow flexibility and fun with or without Rhino and GH, so have fun. All 4 libs should be placed in a folder (maybe called 'tetgen') in your GH libraries folder. Remember to unblock.
Once again, the libs are provided as-is, with no guarantee of support for now, as I use them internally and do not intend to develop this into a shiny, polished plug-in. If there is enough interest, I can tidy up the code-base and upload it somewhere if someone more savvy than me wants to play.
TetgenGH.gha - Grasshopper assembly which adds the 'Tetrahedralize' component to Mesh -> Triangulation.
TetgenRC.dll - RhinoCommon interface to the Tetgen wrapper.
TetgenSharp.dll - dotNET wrapper for Tetgen.
TetgenWrapper.dll - Actual wrapper for Tetgen.
Obviously, credit where credit is due for this excellent and tiny piece of software:
"The development of TetGen is executed at the Weierstrass Institute for Applied Analysis and Stochastics in the research group of Numerical Mathematics and Scientific Computing." See http://wias-berlin.de/software/index.jsp?id=TetGen&lang=1 for more details about TetGen.
To wrap up, some notes about the inputs:
These are the possible integer Flags (F) values and resultant outputs for the GH component:
0 - Output M yields a closed boundary mesh. Useful for simply remeshing your input mesh.
1 - Output M yields a list of tetra meshes.
2 - Output I yields a DataTree of tetra indices, grouped in lists of 4. Output P yields a list of points to which the tetra indices correspond.
3 - Output I yields a DataTree of edge indices, grouped in lists of 2. Output P yields a list of points to which the edge indices correspond. Useful for lots of things, very easy to create lines from this to plug into K2 or something for some ropey FEA (or not so ropey!) ;)
As this component can potentially create a LOT of data, especially with dense meshes, care should be taken with the MinRatio (R) input. This will try to constrain the tetra to be more or less elongated, which also means that the lower this value gets, the more tetra need to be added to satisfy this constraint. Start with very high values and lower them until satisfactory.
Hopefully shouldn't be an issue, but it's possible that you need the 2015 Microsoft C++ Redistributable.
Happy tetrahedralizing...
UPDATE: The tetgen.zip has been updated with some fixes.

The picture below shows the two question.
Question One I must use data dam, or the component can't batch deal the brep. I don't know why, I have You can give me a solution to make it working normal not using the data dam
Question Two I can not uset the Button component, If I use it, the gh canvas will die with some mouse event--. I have see this problem before in this forum,but there is no solution and explain. I want to know why and How to solve it.
I don't know if I have made my question clear,if not give a message. Thank you! Thank you all.

I have diagonals (bracings) which can buckle in these "non-regular" directions too, and they do. If I could add those values then in the Karamba model I could assign specific buckling scenarios..... I can see another challenge which will be at the ModifyElement component, I will not be able to choose these buckling lengths, in these directions.
Do you think this functionality can be added within short, or should I try to find another way to model these members?

There is no class official programming language, as both C# and Vb.Net are possible on the participant’s side, and all examples will be provided in both C# and Vb.Net. Additionally, we will see how to get started writing full .Net plug-ins. Finally, we will have time to explore user’s own proposals on the third day.
Day 1 Morning: programming introduction in .Net
• The Grasshopper scripting components. Choosing a .Net language. Language developments

• Classes: declaration and instancing. Constructors. Importing a namespace. On3dPoints, OnLines
• Arrays declaration and usage. Lists. Adding to arrays and lists, advantages and opportunities.
Afternoon: patterns

• Example of OOP good code reuse: sorting points by coordinates using the .Net SDK classes
• Lists as input parameters. Trees as input parameters. Usage and limitations

• Passing custom types from a scripted component to another one. Our own code reusability

• Writing a custom Grasshopper component: hacking an exporter for our data to Excel
Day 3 All day: personal project
• Rehearsal on any example from the first two days. A project that you want to start on your own, being it a Rhinoceros plug-in, a Grasshopper assembly or a script. Example might be to send data through network with UDP to Processing

y (movement, protection, temperature regulation) but also the evolution of cultural expression precisely by exceeding the purely indexical performative relations. Designing not only for the needs but for the desires.
Computational couture looks at the creation of exclusive custom-fitted clothing (typical of haute couture) through the lens of a systemic approach, extending the sartorial techniques with 3D modeling and computation-based approaches developed in Rhinoceros and the visual programming environment Grasshopper.
Aim of the workshop is to exert, infuse and expand the sartorial sensibilities to body proportions and dress making into an algorithmic approach that loops through design and fabrication by means of laser cutting and 3d printing for the design and production of a garment. Participants will be divided in teams focusing on specific aspects of the garment related to the production technique (laser cutting or 3D printing).
