in the editing of the paper, the Novice is very easy to encounter some lines can not offset the situation, why not offset it? How do I use offsets?

A simpler explanation is that there is a problem with the form of a curve that cannot be offset, and if it exists in the form of a block, it cannot be offset. Tell you how to use offsets with two different-sized circles:

1, first of all, we need to draw the two circle, mark the center of the distance, and then call the Offset tool, you can also directly enter the command o:

2, you can see the command line instructions, set the distance required to offset:

3, select the object that needs to be offset, here we select the small circle, found that the selected object curve into a dashed line:

4, after the completion can be compared before and after, found that the small circle radius expanded by 50:
