Multiple faces are all ONE face?

But is the model out of scale by a factor approaching 10? If the quick solution also fixes the accuracy then by that method you win and win again.

If you use the tapemeasure tool and pick two points on the written/drawn-scale [seen in the image] it says 500' BUT its modeled at well over 100x times that.
The site is big already... BUT making it that much bigger will probably raise issues with face forming that you don't need, and can easily avoid.
As explained before... use the tapemeasure tool and click two points that ought to be 500' apart on the written/drawn-scale, immediately type in 500'+<enter> and answer Yes to rescale the whole model to be more exactly sized. Recheck the written/drawn-scale with the tapemeasure and two picked points, it should now report at ~500', readjust as appropriate...

Is what you are modeling really 2 million inches long?

Well I am modeling Jerusalem, Golgotha and Calvary at the time of Jesus' crucifixion. And I know, I should've started smaller. XD

In my experience, I always draw the model in true 1:1 scale, with very few exceptions.

Because SU has problems with tiny lines, especially when intersecting 2 curved objects, some people draw at 10X scale, or so. This creates perception problems when using dimensions, or merging different models or from component libraries.

So when I encounter a situation where 1:1 scale will create problems, (or did create so I use UNDO a lot!!), I make a component of the problem and make a copy away from the model area.
I then scale up that copy outside the bounding box, which does not affect the model.

I can then edit or intersect within the copy, and see/make corrections far easier than if I were working at true scale.

After the edit I delete the scaled copy.
