Hi @jostein_olsen you were absolutely right! Thank you for referring me to the linked discussion. I changed the Geometry scaling setting form “Extra large” to “Medium” and it worked (Refer to the link). No more Null points. Thanks for the input everyone 🙂 > [@'PolyCurves may be branching' caused by Geometry Scaling setting?](https://forum.dynamobim.com/t/polycurves-may-be-branching-caused-by-geometry-scaling-setting/40703/2): > > This is caused by the geometry disposing of values after the decimal place in extra large settings. Therefore points which previously had X values of [0.1, 0.2, 0.3, 5, 10] now have values of [0, 0, 0, 5, 10] The solution is to always manage your work so you’re within 100,000,000 units of precision. You can shift stuff whichever way you need/want to go, but from 1 to 100,000,000 is all the digits you get to work with. If you’re using feet then: Extra large will work for stuff as large as [3/4 …](https://upload.wikimedia.org/wikipedia/commons/9/97/The_Earth_seen_from_Apollo_17.jpg) --- _[View the full topic](https://forum.dynamobim.com/t/placing-objects-perpendicular-to-corridor-feature-line-using-corridorfeatureline-coordinatesystembystation/47192)._
