Once you have placed a chain dimension, you can make edits to customize the details. You can use the stretch nodes to adjust the size of the overall dimension, size of the segments, and placement of the dimension text. You can also edit, add, merge, and remove segments to customize the tool. To do so, you will need to enter Edit dimension mode, choose the type of change you'd like to make, then edit away!
