Problem creating new double-point, vertical and horizontal lines

When creating a new double point line, I click at a point on the drawing to start the line.  This moves the relative zero to the point where I clicked and creates a new line (with no apparent endpoint) that rotates around the new relative zero location.  The new line extends far past the drawing area.

When creating a new vertical or horizontal line and I click at a point on the drawing to start the line, a new vertical or horizontal line is automatically created (without me selecting the endpoint). The new vertical or horizontal line extends far past the drawing area.

This is unique to the drawing I'm working on.  I can still create new double-point, vertical or horizontal lines as usual by setting the beginning and endpoints on previously created drawings.  I haven't found a setting to adjust the new line creation issue.

well, from the first glance this is intentional behavior.

The action for drawing "line vertical" or "line horizontal" creates a line with fixed length (at least in versions that are available for public, as there will be update where it will be possible to create line with selection of end point too).

That length may be changed either via command line or via editor in "tool options" toolbar.

Moreover, that last enter value of the length is used with next command invocation.

So I think the issue is related to current settings and in saved length.

BTW, which version of LibreCAD do you use?  

In general, in "Tool options" toolbar for the command there should be UI that is similar to this one (this is from development version)

Welcome timstiger!

I suspect you have accidentally activated the construction layer property in the layer list.
This extends any line infinite.

Thanks for the help. I had accidentally activated the construction layer property in the layer list.
Problem solved.
