Microstation To Find Line Or Arc Of Best Fit.

Hi all

I have a problem which I was hoping someone could help with.

I have entered approx 40 x, y, z co-ordinates into microstation using the XYZ text tool box.

What I would like to do is get microstation to find either a line of best fit or an arc of best fit by selecting a series of points. Once the line/arc has been created I want to know how far away the points are from the line or arc.

After browsing the functionality I have struggled to come up with anything. I am currently using Microstation Select Series 2.

Can anyone help?

(I’m a bit dense so screen shots will help a great deal. Lol)
