Format the Relationships Lines in Primavera P6 Version 8.2

Vikas,

To my knowledge there is no way to reformat relationship lines in P6.  Your understanding of what they mean seems incomplete.  In particular:

Ø  Red – Critical and therefore a Driving relationship,

• I think the relationship line is solid red when both predecessor and successor activities are marked Critical.  Such relationships are always Driving only when using Longest Path.  I.e. under Total Float criterion with late constraints, many non-driving relationships are solid red.  You may restore non-driving relationships to black-dotted lines by using Longest path or by reducing the Critical float criterion to an artificially low (i.e. high negative) number. 

Ø  Solid Black – Non-Critical Driving relationship and therefore has Free Float,

• I suspect you have mis-typed and left out "no".  Critical or not, driving relationships in P6 have Relationship Successor Free Float = Zero.  The predecessor activity of such a relationship can't have any free float at all unless the two activities have different calendars. 

Ø  Dotted Black – Non-Critical Non-Driving relationship and has Free Float

• A non-driving relationship has Relationship Successor Free Float >0.  The predecessor activity could still have a lower (or zero) free float if it has other successors.

Good luck, tom

Might be a good idea to throw in the Relationship Total Float and Relationship Free Float columns into the relationships tabs in Activity View. I've shown how to do this towards the end of this article here: Relationship Float, and viewing in Primavera P6 | Australasian Project Planning (austprojplan.com.au)

All Right - Thanks Dear Tom Boyle 

All Right - Thanks Dear Santosh Bhat 

unless its a small schedue do not show relationships you will have a cluser of lines
