If I understand you correctly, you just want to symbolize an existing
LINESTRING feature with double lines. You don't want to add additional
parallel features, correct?
If you look at the new symbology engine, you can stack multiple lines
upon each other. F.e. you can create a thick black line and add a tinner
white or yellow line on top of each other. This way you symbolize line
features and they appear as a double line. You can also create two lines
and offset them from the center.
For snapping, the center of the line will be used.
Is it this that you are looking for?

Thanks for the information! We have looked at the CADTools and the
option for drawing parallel, but just to "assign" parallel lines to
existing line objects. What we are basically looking for is tool to
draw double lines in a separate layer, but in a way of snapping some
existing line in the centre of double line.
Thanks,

In the cadtools toolbox you have a tool do draw parallel lines.
