Selection and measurement how-to showstopper...

Hello,

I'm trying to start with very simple actions: import an image and scale it so that I can read the real position of any point in mm. Import is fine. Then, I try to measure the distance between two points. I select the |<--?-->| icon. I get the message: Specify the first point. I click and see a small red spot with the message: Specify the second point. I select a second point, but get: Specify the first point.
Other question. I was able to create points. They are either showed as a red dash rectangle, or a white rectangle with a circle inside. Which one represents a selected object? Trying to create a line between the two points gives the same result as above.
Tried the help/duckduckgo/forums but couldn't find any answers.
Any help welcome.
Thx

well, which version of LibreCAD do you use?

The distance measuring action simply produces output of measured value into Cmd widget - please check whether some output is present there.

In 2.2.2-alpha (https://github.com/LibreCAD/LibreCAD/releases/tag/2.2.2_alpha-latest) there is a "Informational Cursor" tool that provides indication of distance between points in visual way near to cursor.

Something like:

 

As for the second question - sorry, I not sure I got your point. Which command do you use for creation of line?

Btw, are you sure that your current layer is not hidden? Potentially, if you don't see the line - it might be created, yet if the layer is hidden - it will not be visible.
