Can anyone offer any advice for a fix on this, I suspect it may be something to do with either of the programmes themselves as I cannot send even the preloaded Revit models through to ROBOT without getting the same error. Am I making a basic silly mistake or could this be an issue with my software?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="sbutterworth2112_0-1624504871713.png" style="width: 400px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/933900i8CBA7EEF71F61BC0/image-size/medium?v=v2&amp;px=400" role="button" title="sbutterworth2112_0-1624504871713.png" alt="sbutterworth2112_0-1624504871713.png" /></span></P><P>&nbsp;</P> Thu, 24 Jun 2021 03:30:55 GMT https://forums.autodesk.com/t5/revit-structure-forum/quot-object-reference-not-set-to-an-instance-of-an-object-quot/m-p/10416378#M14534 Anonymous 2021-06-24T03:30:55Z Re: "Object reference not set to an instance of an object." error when sending a Revit model to ROBOT.
