Support Blocker - Cube Placement - Problem/Bug? Cura 3.3.1

Recommended Posts

Hi everyone,


today, for the first time I wanted to try to Support Blocker function available in Cura 3.3.1. The function, as is, works fine, however placement of the blocker cube is a nightmare.


Consider an example when you do not want any PVA support in small horizontal through-hole, like this one:



As I understand if I want to block the support I select the body of the object, then select "Support Blocker" and then click the red area visible on the picture above.


Aaaaaand nothing happens, however after changing the camera view I find a very distant dot, far away from the printer workspace:



If I'm very very precise with my mouse I can select them, then enter the 0,0,0 mm position in the Move menu and then use the blocker cube as intended.


Am I doing something wrong? How should I select the area for support blocking? Or is it a Cura bug?
