In my very first LibreCAD drawing, I managed to draw the square outline of my sheet of starting material and then to lay out a series of about seventy entities, ultimately intended to become separate objects in a planned laser-cutting operation. Upon each such entity I placed an identifying number, intended to be etched into the starting sheet before commencing the cutting operation.

All of this I did in Layer 0; there is no Text layer to my drawing.

That left me with the square outline of my starting material with the numbered drawings of the seventy-odd objects.

OK so far. But the process of etching the identifying numbers into the starting material requires different laser settings than the settings of the laser cutting operation, so I set about separating the drawing into two different files with suitable names, an objects-only file and a text-only file. I easily accomplished this be starting with two identical files, each with everything nicely arranged on the same square area. Then I deleted all the drawing information from one drawing file, leaving just the nicely arranged text data, and then deleted all the text data from the second file, leaving all the object outlines, absent the identifying data.

Now comes the punch line: after removing the text data from the objects-only drawing, after a finite delay of about one second, infinite construction lines appeared along the four edges of my square outline.

Removing the Help layer of that objects-only drawing did nothing.

I need to find out how to hide those construction lines, as they are bound to confuse the laser-cutting machine.

There were no construction lines apparent when this was a layer0, objects-plus-text drawing.
