When showing baseline view it can be very confusing to distinguish task link lines between the baseline tasks and the currently scheduled or completed tasks. In order to clean up the view it would be very helpful if we could turn the link lines off for the baseline, while leaving them on for the currently scheduled tasks.
This has been implemented in the SYNCHRO Plugin for Microstation version 6.4 released in June 2021
To turn of link lines for baseline tasks, open Plan>Gantt Display Options. Disable Baseline Links under Indicators. When Baseline Links are enabled, whether or not they are shown is controlled by the Show Links setting
