However my surface does not seem to have a border to extract, even when I turn it on in the Surface style display bar. The Layer it is on is displayed and unfrozen, and other features on the same layer work just fine. Any ideas?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.png" style="width: 400px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/534179iC748B2069E420A0E/image-size/medium?v=v2&amp;px=400" role="button" title="image.png" alt="image.png" /></span></P><P>&nbsp;</P> Mon, 13 Aug 2018 16:46:49 GMT https://forums.autodesk.com/t5/civil-3d-forum/surface-has-no-border-to-extract/m-p/8196082#M141067 tlincolnAY44Q 2018-08-13T16:46:49Z https://forums.autodesk.com/t5/civil-3d-forum/surface-has-no-border-to-extract/m-p/8196153#M141068 <P>Be sure that layer is also On, not just Thawed.</P> Mon, 13 Aug 2018 17:15:09 GMT https://forums.autodesk.com/t5/civil-3d-forum/surface-has-no-border-to-extract/m-p/8196153#M141068 tcorey 2018-08-13T17:15:09Z https://forums.autodesk.com/t5/civil-3d-forum/surface-has-no-border-to-extract/m-p/8196196#M141069 <P><SPAN>Border layer is&nbsp;both on and thawed.
