Cannot select parts in opened project containing a support blocker (Cura 4.10.0)

[krikru 1]

When I create a new project and add an stl model and a support blocker, save the project and then reopen it (it doesn't matter whether I choose "Open as project" or "Import models"), I'm unable to select the model or the support blocker individually. It doesn't matter which one I click on; all I see is this image (the reason it's dark gray is because I have created a custom filament which is black):

 

 

I can still slice the model and the support blocker will do its job properly, but I cannot select the support blocker to move it to reshape it. I can create a new support blocker, and then it seems I get two selectable objects: 1) the model and the support blocker loaded from file, and 2) the new support blocker. In this image I have selected the former:

 

 

The disability of not being able to select the support blocker and the model individually, plus the inconsistency between support blockers loaded from a project file and newly created support blockers, makes this feel as a bug, so I tagged this topic as a bug.

 

I'm using Cura 4.10.0.

Can you right-click and Ungroup?  CNTRL+left-click any object?  Select from the object list in the lower left of the screen?

You can control click to select items within a group.

 

That being said, it shouldn't suddenly add a group. Could you also report this on github (https://github.com/Ultimaker/Cura/issues/new/choose)

Ah, so that is how you do it! 🙂 Okay, well then it's just me not knowing Cura well enough.

 

A question along a similar line: If I have two objects, of which one is completely inscribed by the other object, how can I select the innermost object?

[GregValiant 1,141]

If it isn't part of a group it will be available in the object list on the lower left.

There may be a way to cycle through the objects of a group but I am unaware of how to do that.
