You mean inside a scripting component? They are the same as in .NET.
Either google for "VB.NET string" or inside a VB component type: dim bla as string
bla.
and a list of methods will appear :)
I´m trying to visualize some text data on points of a brep that comes from a script.
It´s just a matter of making it faster (only one line of code) and not to have those points outputted from the script component (which I´d only use for that purpose) and then use a gh text tag.
I was just curious about it but if it´s so cumbersome I will do it the other way.
