many short bridges, do not need supports. 
lots of people notice the lack of supports and think it is a slicing fault.

Thank you very much, that was the issue. I didn't even know that there was an option like that.

What is the point in that anyway?

Regards

Zsolt

 that might give the issue that you describe

I made an STL with Tinkercad and wanted to slice it for printing as usual, but I got a strange issue, at one point where there should be, no support is calculated.

How can I fix it or force a support?

Thank you in advance,

Zsolt
