4s2p = 4signal 2 power cross section. 6s4p= 6signal and 4 power cross section.
I've also seen spssps.brd signal/power/signal/signal/power. Or
spspsspsps.brd
Whatever works.

Thanks Bill, I'd call that a bucks worth!
I too use a start board, then run one of the setup scripts I've created for
number of layers (2, 4, 6, 8, 10, 12 & 14) and format size (B, rarely used, C,
D & E). The scripts also sets up films, drawing formats, stackup diagrams,
notes etc.
I'm not sure what "4s2P", "6s4p" etc. stands for though.

Constraint Manager dcf files do not contain Drawing Parameters information
that a Technology file will contain.
Technology files were introduced before the Export>Parameters was added.
Technology files were also introduced to allow the
Comparison of a Golden file against a board to make sure it meet a standard
before being released.
As far as who uses what and why I cannot answer that. I prefer to have start
boards setup for particular technologies.
4s2p.brd, 6s4p.brd etc. I use these to import logic then do a file save as.
These databases are clean not carrying any extra's in it.
Padstacks are purged dbdoctor run etc.
My 2cents

Hey guys,
Do you use either technology files (.tcf) or constraint files (.dcf) from
Constraint Manager (CM)?
If so, which one and why? I've played around with them in the past, but
typically don't use them. If I'll start a design similar to a previous one, I
just use the older similar one as the starting point and delete all of the
components/traces/vias.
I have someone new to Allegro (just had formal training) in another group
asking about .tcf files.
Thanks for any clarification you can give me regarding these CM files.
