Open the Sheets panel in the left-hand sidebar of the Drawing Tool.
​

If desired, click the Expand icon at the top right of the Sheets panel to expand the panel to a full window view.
​
​

​

Scroll as needed to locate the sheet(s) you wish to reorder.
​
​

Click, Ctrl+Click (Cmd-Click for Macs), or Shift+Click to select the sheet(s) you wish to reorder.
​
​

Click the drag handle to the left of a selected sheet.
​
​

​

​
​Note that descriptive sections in the specification will also be reordered to reflect this change. Note also that, for autonumbered figures, part reference numerals will be automatically updated in the figure(s) and across the specification and claims.
​​

If needed, click the Collapse icon at the top right of the expanded Sheets panel to return to your figure canvas.
​
​

​

Navigate to the last figure in the subnumbered set.
​
​Where multiple sheets display a set of subnumbered figures having the same number and distinguished by an alphabetic suffix, e.g., FIG. 1A, FIG. 1B, and FIG. 1C, those sheets must be moved together.
​

Starting with that last figure and working forward, remove subnumbering for all figures you wish to reorder.
​
​For example, if you have FIGs. 1A-1F, and you only wish to swap FIGs. 1D and 1E, you will need to remove subnumbering from FIGs. 1F, then 1E, then 1D.
​
​

Reorder the individual sheets and figures as desired, as described above.
​
​

Reapply subnumbering to the figures if desired.
