Array along non-linear path

Since you know each chair is .5, dividing the respective B lines by .5 will tell you how many can fit. Then actually divide the B lines by that number. This will give you the centres of each chair. Use Component stringer to place the chair at those points.
You would probably find it easiest to make blocks of seating, just like they do in real life, and use the various blocks as components to populate the whole stadium.
Well, by doing that I would still need to measure the length of that lines first, wouldn't I?. That won't save me much work, as I would then be faster by the method Pilou mentioned
The second hint I do not really understand. I do have blocks in my stadium and I only model 1/4 of the stadium anyway, since this is enough to complete it afterwards by making this 1/4 a component. However, each block is different, because the shape of the stadium bowl is not symmetric or should I say "regular". So each block has its own seating pattern unfortunately ..

Click on the line with entity window open and it tells you the length of the line.
It's in metres, your seat is half a metre which means two per metre plus one if the line is over .5
Eg; line is 36.75m number of seats that will fit 73, line is 36.49m number of seats that will fit 72As to making blocks. Make sections of seats in the same way the manufacturer would. Runs of 10 and 5 etc, so you can just throw together whole sections and not individual seats.
So line is 54.87m that's 10x10 + 1x5 + 2x2

This what you want? Rotate the chair any direction and scale it to the right any length.
You don't list in your profile if you have the Pro version this is a dynamic component.

"because I have like 90 rows and 15 lines in each stadium, so I'd need to do that 1350 times"
I am quasi sure that you have some symmetry?
And you can make some copy / past ! -

Anyway, thx for the effort!
@Pilou: Yap, for sure
I only model 1/4 of the whole stadium and then copy & past This is what the stadium looks like without seats in them yet:
-
Multiple straight lines and repetition of blocks.
Would take very little time to populate it with seats.
If you filled it with seats it would also slow the model down. -

i think it should be more like this:
**pretty sure the spacing formula could be refined to something more simple but this is the first gobut you'll see in the .skp that the block starts and ends at exact points then the gap is populated accordingly.. it could maybe use an if/then statement to set a minimum spacing if desired..
this should&could be a distribute plugin imo.. select the component then click on the start and end points.. 1001bit almost does it with one of it's linear array options but not quite..**

Except that the spacing you have gets narrower with the greater distribution, and I thought he wanted repetition on spacing, with the row ends being the adjustment. As in, start at the center and scale out to both ends, leaving the remainder as the row ends.

hmm.. yeah, maybe.. not really sure as i've never dealt with stadium seating layouts.. i just assumed the row ends formed a straight line when going up a column.
but it seems to make sense from a manufacturing point of view to have the spacing remain consistent.. your version of the DC could be updated to where it centers the array upon scaling the length.. that will save a few extra steps of moving it in place after scaling.
i guess it depends on whether or not liverpudlian wants to use a DC for this or not (though it's definitely going to be the quickest way imo)

Erm, actually I want the spacing between seats to be varible, with the first and last seat exactly on the start and end of the row (as indicated by the image in my opening post) ... otherwise one gets ugly looking "kinks" in the stands like this:
I prefer the solution with variable spacing in each row, as this will look smoother in a stadium like this:

Jeff, you got it

Will be interesting to see how this goes or if SU can handle all those seats.
Find it hard to believe people crowd into those nosebleed tiers to watch that crap. But of course they do. Everyone to his or her own. Not that I've never enjoyed being at a game myself.

hmm.. i don't think i want to be the one that finds out
here's a low-poly dynamic chair (120 faces).. i'm not sure if this is a real style design but i guess it would have to be done similarly in order to get variable seat spacing.. after doing a small sample, you might want to consider making it even more low poly..
how to use:
in doing the example, i encountered one situation where the DC would no longer update.. i had to save the file at that point then relaunch sketchup in order to get the DCs working again..
there's a guide point in the seat which can be used as a reference to rotate the seat into an upright position..
good luck

Wow, thx @Jeff!

Dear Jeff or other some kind soul can save this DC file in SU V 7 ?
Thanks by advance!

thanks.. i kinda wish i knew ruby though because it seems like it would be better and more useable that way

Dear Jeff
Does it possible to have a DC component with a "rounded" structure against a "straight" structure ?
