why is tool orientation different from flange system when toolABC are all 0?

[harper]

Hi there!
This problem has confused me for a long time. When the ToolABC are all 0, I suppose the XYZaxis of tcp should be the same as the flange system according to the difinition of TOOL cordinate system. But as the image shows, it's the same as rhino XYZ axis.

Hello,

You can switch the tool axis to Z in the settings if it annoys you. In general, using the X-axis makes the XY planes in GH easier to use.

But I understand that it's not an ideal solution in either way.

Best,
