When drawing elements such as walls, railings, edging and fences, new segments are continually added as you pick more points. You can use the Repeat tool to finish drawing the current line-drawn element and start a new one if you want, without having to restart the tool.
To repeat the insertion of a line-drawn element:
When you are ready to finish the current element and start a new one, right-click and select Repeat, or select Edit > Modify Elements > Repeat. The current element is finished.
Pick a start point for the new element and continue drawing.
Note: The Repeat tool is available for line-drawn elements only.
