I created a polyline from segments to hatch a surface. I then copied the drawing, removed the hatch and wanted to go back to individual segments so I selected the polyline and selected "Explode" from "Modify".
I do end up with segments but the line width has changed and I cannot modify it through "Attribute" and "Undo" (or Control+Z) has no effect.
At the moment, all I can do is to re-draw each line.
Is there something I do wrong or is it a bug?
