I saw that people mark there system with a line so they know when to add more water. Where's the best spot on the aquarium or sump to draw the line so I know when to add more Ro di water?

I don't have a direct answer for you but often times your skimmer will operate optimally at a certain point, I would use that water level as an indicator to add your water. But what I would really recommend is that you invest in an ATO system so that water is replenished as evaporates, this will a) keep you from having to monitor evaporation, b) potentially forgetting to add water, and c) keep your parameters more stable.
+1 @shornik, invest in an ATO. Set your ATO float/sensor/etc at the desired water depth. Determine this by your equipments needs, as mentioned a skimmer, but your return pump, heater, over flow, etc. Utilizing the available volume and assuring your equipment successfully functions should dictate your water level... More or less.
If you have a traditional sumped tank with baffles in the sump then the only part of the setup with varying water level (while the tank is running) is the compartment with the return pump. So, to answer your question directly, the only place marks would be useful is the compartment in your sump with your return pump. Now, how you decide what's the maximum level depends on your overflow volumes etc.

Still new is that good or bad?

ATO is auto top off, or having a device that will automatically keep the tank topped off properly.
Using lime/kalkwasser is a popular method of replenishing the minerals that corals use to grow.

+1 - this post is confusing, there is only one place you could possibly mark this, the only place that loses water, which is the return chamber of your sump. Even if you have no compartments in your sump you'd still mark it on the sump.
Do you have a sump or are you doing research into what all needs to be considered?

Based on your sump configuration, then the return section on the left is where you want to mark and monitor your water level. Again an automatic top off system will make it much easier than manually topping off.

I have a sump
Your far left chamber on that sump. First get your system running how you want it with the correct water volume, then make your mark on that compartment. Then what I did is turn off my return pump and let all the water run back into my sump, then marked where the water settled. Then removed water into a home depot 5 gallon bucket to the point about 2" from the top and made another mark. This indicates where I need to drain water to for a water change. I use a python water remover so I needed to know where to drain to. In my case, I actually removed two home depot buckets worth of water since I change 2 buckets at a time. I won't say "5 gallons" since I don't fill the buckets all the way as it would slosh around too much.
