<p class="MsoNormal"><span lang="EN-GB">Hello,<br/>
I wanted to ask if there is a tool that allows me to adjust the points of the brown area to match the red boundary. Unfortunately, there are a lot of points, and doing it manually is no longer feasible. The brown area also contains many attributes that I would
like to keep unchanged.<br/>
Does anyone have an alternative approach or a better workflow for this?<o:p></o:p></span></p>
