Hi @ZW_10422446 

Thank you for your question! 

I’d like to recommend to bring more details and context to your initial inquiry. For example:

• Could you clarify what you're hoping to achieve or understand in this case?
• Are you trying to duplicate a segment of a curve within the same sketch or as a separate feature?
• Should the duplicated segment be editable independently, or remain linked to the original?

Please add screenshot(s) to better understand what you are trying to do in your process.

How to duplicate a local segment of a curve in a part and make the end point that generates a duplicate curve coincide with the two coordinate points

Your request is a bit vague.  Is this what you are trying to do?

References / chain details / options: Change each end to trim at reference and select the desired reference (point, plane, line, edge, surface, etc).
