Hi Craig, large coordinates like that will tend to cause a variety of problems because the way floating point numbers work is that there are wider gaps between representable numbers the farther away you are from the origin.

Basically all arithmetic operates at a lower amount of precision when working with those large numbers.

Complex operations like Booleans and Fillets will be more likely to fail.

So it's not generally a good thing to do, there is a lot more downside to it than just eating up window space.

It is possible to edit the UI to widen that control though. What version of MOI are you running? It may need to be edited slightly differently in v4 or v5.

Good to know, I appreciate that info. When using Moi for this purpose it would more with features like loft or sweep. The shapes are pretty basic for draining parking lots and around buildings. I'm using V5 on Mac. The surface creation tools in the TOPCON software are so clumsy and primitive. It's much easier to use Moi3D.

Hi Craig, from Finder click the "Go" menu on the top menu bar and choose "Go to Folder..." and put in:
~/Library/Application Support/Moi/startup

Then copy the attached ExpandCoords.js file into there.

After that when you start up MoI that script should run and make the space for xyz coordinates larger.

Hope that helps, - Michael

Perfect! Thank you! This allows me to select the point creation tool and run around on surfaces, edges, etc to quickly check grade. I don't often need more than a couple decimal places but this leaves me plenty of room.
