I installed DoubleCAD XT v5 and I'm very glad to find the Through option for the Offset command.
But now the Rounded Corners option is disappeared and set by default so every offset operation get rounded corners. It's so annoying.
Do you find some solution to get an offset for a polyline without rounded corners?
Using the “Parallel line” command or exploding the offset polyline and then rejoining the segments with “Meet to line” command is really an inefficient procedure.
