Visio file that shows dashed lines at different weights
Visio defaults to round line caps, which in turn means that dashes and dots in a line style are also rounded. When LibreOffice imports a Visio diagram, lines are created with a square cap. See attached file for an example.

This bug is actually LibreOffice internals' bug. The svg:stroke-linecap property is properly fed to LO, but it is ignored. Regina Henschel is working on this problem. But it will most probably not be part of 3.5
Assigned to Regina, since it will be solved once her implementation is out there.
The line-cap feature is nearly finished. But part of the solution is written by Armin Le Grand and therefore with an Apache license. So integration in LibreOffice has to wait until it is allowed to use this license, hopefully with LO3.6.
*** Bug 53455 has been marked as a duplicate of this bug. ***
Round Caps have been implemented in 4.0, but this bug is still there.
I do not work on Visio import.
I see this bug fixed in LO 5.0.3
