I am looking at the following entry for the Repairbay2 in buildings.CSV and trying to interpret what each item means
RepairBay2,26,34248,BUILDING,79,,1,0,0,0,0.8,0.4
 Here is what I have come up with so far based on the first line in buildings.CSV
Name ID                            RepairBay2                     
Group ID                            26
Name ID                              34248   
Type                                   BUILDING
FIT ID                                 79
SPECIAL TYPE                    ,
ALIGNMENT?                      0
CAPTURABLE                      0
Draw Building On TacMap  0
TGA Filename (if any),        0
Mechlopedia Scale             0.8
Mission Briefing scale        0.4
I am interpreting that the ,, after BUILDING means that the next entry (SPECIAL TYPE) is blank.  There are other entries where ,, is used as well.
Now lets look at a mech entry
Jaegermech3,21,34049,MECH,1248,,1,1,0,0,,1
It has two places with the ,, - in this case I believe that means that Mechlopedia Scale is blank/not used.
About my last post concerning FIT files - Notepad reads them just fine. Is this what should use to modify the FIT files?
Another question. You have the following in step 1:
Fragment from corresponding FIT file (in Object2):
“FITini
[ObjectClass]
l ObjectTypeNum=1
[ObjectType]
st Name="RepairBay2"
…”
 It is NOT clear to me what the "corresponding FIT file  (in Object2)" is.
in "1.3
Every mech must have a file MCL_MC_ MyMechName.tga. It is used for mechlab in logistics."   Just to clarify: Are these the files located in MechCommanderOmnitech\data\art?
I think that's all I have for part 1. Now I get to go fix supper and later on back to reading this again.
