I drew about 8 concentric circles. I selected them all and used the Concentric constraint.
Later I cut arcs in these circles and added radial and other lines to them.
When I zoom in to a resolution of 0.01 mm, I find that the centres of these arcs is no longer concentric. Is there anyway I can make make these arcs concentric again without having to delete the radial / other lines that connect these arcs?
The image of the centres in the zoomed figure is pasted below:
An image of the arcs and connecting lines is below:
