No, you do not need to add lines for each circle. I draw multiple circles to demonstrate the situation. If you have this kind of situation in your project so you don't need resolve at that time and you know the reason why it happens. If you have any other doubt or problem regarding AutocCAD feel free to ask. All queries are always welcome. Thanks for sharing your feedback.
Bro, it is located in the annotate tab. may be you are in Home tab. That's why it is not showing. To activate, follow this steps: 1) Click on Annotate tab 2) click on Centerline or Centermark tool (according to your need) 3) apply on object. If this not work for you, then use its command CENTERLINE or CENTERMARK.
To be honest, it is quite easy. First create new layer and renamed it to Centerline or anything you want. Secondly, select all centerline which you want to hide and move them to centerline layer you created. Lastly, turn off the visibility of centerline layer from the layer manager. And boom your centerlines are hided successfully. Hope you find your answer. If you have more questions, feel free to ask. Have a nice day.
