Hello
I have a strange behavior in Grasshopper Canvas. When I select a component all the wires disappear.
Same thing when I connect.

I have seen this before when the wire colors were changed by a script (alpha values set to 0).

  1. In Grasshopper, select File > Special Folders > Settings Folder to open the folder containing Grasshopper setting files.
  2. Open the file named grasshopper_gui.xml and find the values for wire_selected_a and wire_selected_b
  3. If necessary, change the settings to the default values shown here:
    wire_colors
    wire_colors1788Ă—280 62.9 KB

You can also view or change these values from a script by accessing these fields:

Grasshopper.GUI.Canvas.GH_Skin.wire_selected_a
Grasshopper.GUI.Canvas.GH_Skin.wire_selected_b

If modified by script, values will be saved to grasshopper_gui.xml when you exit Rhino.

You can also delete the grasshopper_gui.xml file to reset all settings to default values (the file will be recreated when you restart Rhino).

Thanks it works.
I was just on this lead. Like seen on another thread most of my xml were modified recently, so I suspected a plugin. I just recently installed Fennec. I uninstall it. But I am not sure it is this one.
