Hi SUIYAN, thanks for describing it. For the case you show there where you want to locate the circle's center point at a displacement of 70 in +x and 200 in -y you can use a relative point input for that.

That would go like this: start the circle command, then type r70,-200 and push Enter. Now you should see that when you move your mouse around the point that will be used is shifted by 70 in x and -200 in y, so snap on to the corner of the rectangle and you should get the displaced point you want.

If you want to do one with multiple steps the closest thing to that would be to draw a helper polyline using the new Left/Right polar coordinate entry.

To do it like AutoCAD tracking where you can activate a mode in a general point pick may be kind of difficult since there isn't an existing place in the UI to show how to finish the mode.
