Those diamonds are referred to as `connect points' (cpoints) and the size can be controlled by the `Connect Point Size' parameter in Setup >Design Parameters; Display tab.

Connection points are created when a connection (cline) outside a group is connected to a cline that is in a group. This can be from the use of modules, partially routed connections that then go to the SPECCTRA router or partitions.

The cpoint is created so that the original cline remains unaltered in the group. Normally the new cline would merge with the group, thus changing the aspect of the group. Cpoint functionality can minimize lost information that is a result of merged overlapping and or deleted clines.

You cannot add cpoints or manipulate them. They are displayed as a diamond on the clines.

You can use the following methodology to remove the cpoints if you really need to.

First disband the groups (Edit > Groups). Now simply pick up all the etch on all layers and then place it down in the same x,y location. This is done using Edit > Move with the Find Filter set to clines and vias. Select all the etch by window. Use 0,0 as the pick origin and then use 0,0 as the destination. Once the diamonds are gone you will be able to slide or route the etch as a single cline segment.

Alternately after disbanding the group, you can slide the cline to remove the cpoints.

If the clines and nets have the `fixed? property make sure you remove the fixed property before edit > move.

Also refer to Allegro OnLine Help "Connection Behavior in Groups" for more information about cpoints.
