Have tried to select by the ID presented in the error message, but am told the ID is invalid. Am currently trying to manually comb through the IDs, but having little luck.<BR /><BR />Please see the family attached.<BR />Do let me know if&nbsp; you can find the culprit!<BR /><BR />Thanks<BR /><BR /></P> Wed, 16 Oct 2024 11:24:51 GMT https://forums.autodesk.com/t5/revit-architecture-forum/cannot-identify-id-of-the-invalid-extrusion-base-sketch/m-p/13087882#M10844 Max_Irving-Lamb 2024-10-16T11:24:51Z https://forums.autodesk.com/t5/revit-architecture-forum/cannot-identify-id-of-the-invalid-extrusion-base-sketch/m-p/13088233#M10845 <P>The issues are with 1750H and 1750H2</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="1750 H.png" style="width: 300px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1422224i54DBDB1FB07C4F26/image-size/small?v=v2&amp;px=200" role="button" title="1750 H.png" alt="1750 H.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="1750H2.png" style="width: 300px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1422223i756B6BB365FE65BD/image-size/small?v=v2&amp;px=200" role="button" title="1750H2.png" alt="1750H2.png" /></span></P> Wed, 16 Oct 2024 13:42:31 GMT https://forums.autodesk.com/t5/revit-architecture-forum/cannot-identify-id-of-the-invalid-extrusion-base-sketch/m-p/13088233#M10845 Revit_Whisperer 2024-10-16T13:42:31Z https://forums.autodesk.com/t5/revit-architecture-forum/cannot-identify-id-of-the-invalid-extrusion-base-sketch/m-p/13088338#M10846 <P>Thank you!
