Hello Lucius,
Great model with lots of detail!
May I ask where you got the measurements of the aqueduct from? I have to make a 3D model of the pont du gard for a school project and while I can find some measurements online (like the height of the different tiers) I can't find all of them (like the height of the arch itself, or the position of the middle tier on the bottom tier). Also, the information I found is often inaccurate. It would be really helpful if you could tell me where you got the measurements from.
Thank you in advance!
