Hello, I fail to remember how to display a simple vector with python in grasshopper :sweat_smile: ? So what’s wrong with this code ? nothing appear in my viewport where it’s supposed to be :confused: import ghpythonlib.components as gh import Rhino.Geometry as r vol,centr = gh.Volume(x) a =…

Here my tinny bug linked in the gh file. thx for any help. import rhinoscriptsyntax as rs import Rhino.Geometry as rh import ghpythonlib.components as gh import math ab1,ab2 = gh.Volume(x) ab1 = math.floor(ab1) ab3 = “Volume= “+str(ab1/100)+” Units” print(ab3) a = gh.TextTag(ab2,ab3,[255…

even if the textTag is not linked to the output nothing is displayed in my viewport … :face_with_raised_eyebrow:

Hi, Have you ever managed to display this (even in Rhino 5?) I rarely use the ghpythonlib. But I’m pretty sure that when using display components within the python editor the display pipeline gets overridden. Cheers M

I thx for your answer, I use rh6 and I’m not used with the ghlib, i will wait and see a probable answer from @piac , beyond that the ghpythonlib is designed to be be user friendly and there what is happening is not intuitive at all (for me) so may be we are going to see more trough this in few hours. …

Hi @julz ghpythonlib is a library that allows to use Grasshopper geometry functionality as a simple functions. This is intuitively also its limitation: only components that act as pure functions work. If they work for other side effects or purposes (like looping, in Galapagos, or like the Timer, f…

One option I’ve been using since forever in GHPython is the CustomDisplay class. It’s pretty basic and comes with its own issues, but is generally quite functional for a lot of things. I’ve written some helper functions I can share to work around some of the issues, if need be.

Every things is think for a specific use, and there no real need to go further following my need thx @piac for your quick feed back AndersDeleuran thx anyway.

Hi @AndersDeleuran , I would happily take a look to those “helper functions” edit: if still they are available thanks

They sure are: [image] How to redraw the object created by customdisplay? Grasshopper Developer The approach I generally use is to clear the custom display each time the component runs. In GHPython, I stick a persistent custom display into the sticky dict (enabling one to…

[image] piac: When available they will actually run, but they run in their own Cluster @piac , could you please elaborate this part? I would like to know what is happening “behind the curtains”.
