Hi guys, i want to segment vessels and downloaded the SegmentEditorExtraEffects extension to use the “Draw Tube” option. However, the icon for fiducial placement stays “gray” and doesnt work when being clicked on. Can someone help me? Thank you!

Could you please test if it works well in the latest Slicer Stable Release (5.0.x)?
