“Object reference not set to an Instance of Object” getting this error while try to create duct by curve
I am new to Dynamo, I need to know why this error appearing and what is the error telling and how to rectify this error
Hi @hariharan which package is this node from ? could it help with lacing to longest…another way is instead of taken endpoint and startpoint then just take the curve itself and try MePover duct by line or Open MEP package duct by line…btw i think your node support round duct and not rect as it seems you feed in
