to help with detecting "not changed" event when taking
Undo/Redo snapshot or synchronizing with the back-end.
Converted layer height profile and supports / seam painted areas
to the same timestamp controlled structure.
Drain holes reference position was saved slightly above the mesh to avoid problem when the hole is placed on flat or nearly flat surface
The depth of the hole was internally bigger than what the user has set to compensato for it
However, this leads to problem with scaling and makes reprojection of the holes on the mesh complicated
This commit changes the reference point to the point on the mesh and the extra elevation is handled when rendering and drilling the hole.
The change is reflected in 3MF drain holes versioning so that old 3MFs are loaded correctly.
Reprojection on the mesh after reload from disk/fix through netfabb has been enabled.
Removed unused code
Fixed a clipping-plane related crash
Fixed a crash in hollowing gizmo when no hollowed mesh was provided
Forbid opening the gizmo when a part of an object is selected
ObjectClipper tracks active mesh (incl. possible hollowing), remembers clipping plane position and can render the cut on demand
Hollowing gizmo uses the new infrastructure
The showing/hiding block cannot depend on whether the mesh was recently updated.
It would then not hide the supports and pad, which are calculated later than the hollowed mesh.
If the clipping plane is moved automatically after hollowed mesh was created, move the clipping plane and fix current direction so it is not reset when user wants to move it
This is a quick solution for the 2.2.0 release. It should be later refactored as mentioned in the code.
Clipping plane direction is now initialized when the plane is first moved, not when the gizmo is opened. This is how previous versions worked.
This is a minimal-effort solution before the clipping plane is refactored properly.
Drain holes are not allowed to be placed on its own inner surface. This was recently (0e3ebb3)
done by forcing invalidation of the slaposDrillHoles, which also invalidates and therefore
hides the drilled mesh. However, that also hides the hollowed mesh and it is not possible
to place holes inside the cavity.
This change does not dump the drilled mesh, but checks that no raycast hit ends up in a hole.
