Supports of one object go through another object

[jindrichbenes]

ver. 1.35.0.7

two separate objects

[bubnikv]

Supports are generated per object, and collisions of objects are not tested by Slic3r. This is a known issue.

why not combine/merge objects into one first and only then slice, generate support, raft etc
For anyone who found this issue here - there is one simple solution currently - it is possible to select all the objects, then right-click and choose "Merge" - this will create single raft/support.

Bonus tip - you can always chose undo to rearrange.

@lukasmatena I just came across this issue: as an easier alternative to automatically fixing this, would it be possible to detect overlapping gcode and show a warning 'The gcode is overlapping. Merge the models to fix this'? I just had to scrap a large part because of this issue.

[lukasmatena]

@redfast00 It is a possibility.

7 years on and still an issue. :(

there are 2 other, "interesting" side effects / fallouts of this bug, namely:

• when using --duplicate cmd line option objects are auto-positioned incorrectly, causing collision with supports
• when running from cmd line, slicing ends up with SEGV

see #13464 (closed as duplicate) for more details.
