A problem with PROE rookie drawing hand wheel, please people generous with your criticism
Variable section scan or mixed scan. Then the array.
In fact, the big ellipse is mixed into the small ellipse, and it can be finished by mixing, variable section scanning and scanning mixing.
Variable cross-section scanning! You draw the outer ring and inner ring first, so that the scanning path can be positioned, determine the cross section of each position, then sweep out, and then a circle array!
