Measure Tool Not Working

Hello,

The measurement tool has stopped working for me. I was taking measurements and I got a lot of decimals so I changed them to just 1 and since then the tool has not worked. Every time I try to measure a line (point to point) nothing happens. I have tried to make LibreCAD return to the default options but nothing has changed.

Anyone knows what could be the problem?

I have finally discovered the problem. The "snap on endpoints" option was deselected. It's incredible that something like this makes the tool stop working completely.
