How to unmerge subnets
To unmerge subnets, proceed as follows:
1. Select the menu command Edit > Merge / Unmerge Subnets > ...
Select the type of subnet in the last part of this menu command.
2. In the next dialog, select a subnet in the right-hand field ("Merged") that is to be
removed from the merged subnet.
3. Click the button with the arrow pointing to the left.
The selected subnet now appears in the left-hand field ("Subnets in the
multiproject").
Properties of merged subnets
When you merge subnets, the transferable properties of the master subnet are

subnets) the profile, transmission speed, highest address, and the number of
nodes to be taken into account.
The following subnet parameters will not be adapted - which means that the
individual subnets of a group will maintain their own subnet properties:
