Displacement problem published layers in arcgis online

Question

When selecting the lines that I want to publish to an existing layer, the layer automatically moves. I have identified the error in the curves where the esri etity automatically places points in the crosses of the original cad entities. This is a critical error because it varies the areas of analysis

1) ArcGIS Online does not support curves and neither would ArcGIS Enterprise when working with a hosted layer.
FAQ: Are curves a supported geometry type for hosted feature layers in ArcGIS Online and the REST API?

2) However, any version of ArcGIS Server starting at 10.3 and above does support true curves as a feature service:
- Editor settings for ArcGIS Server feature services: 
- Scroll down to: "Properties that affect editing".
- Scroll to: "Only allow true curve updates by true curve clients".
- AutoCAD is a true curve client.

3) This would mean the data (Feature Class) would need to reside in an enterprise geodatabase.

Hello Félix,

I found your Esri Support case and have posted information to the Analyst. I can post the case conclusion here after the case is closed.
