how to automatically connect lines to arrows and boxes in libre calc

trying build flowcharts in librecalc, and noticed that when I connect lines its misaligned or not really connected up close or not straight.

I’m afraid Calc will not work. You can create your flowchart in LibreOffice Draw. When you’re done, you can copy it to Calc.

You can find out how it works in the documentation:

Draw, Chapter 8 - Organization, Charts, Flow Diagrams and more, starting on page 4
