quote interne

[fast975]

Good morning to all,
I would like to ask for help to insert internal quotas not as the example that simply measures the straight segment.
I would like the quota taken from the outside of the sheet to the middle point of the internal arc.
Is there a chance to get it? ? ?

Thank you, good work.
