Hello World, Ive been attempting this same node and i still get the Null Message
First attempt
Second attempt
In both cases i am having a Null result >.<
HELP
Also, i am using Revit 2019 and Dynamo 1.3
Try upgrading to Dynamo 2.0.3. 1.3 may not be supported by your particular version of MEPover.
Still having a null result!
Group and label your nodes so we can understand why you’re doing what you’re doing. The logic is clearly broken at the Element.GetParameterValueByName node but I’m not sure what you’re after. Also, I have split this into a new topic as you’re pretty far off and this one already has a solution.
I am calling from an AutoCad file a layer to create pipes in Revit with a specific pipe type and system type
to start off im calling the CAD lines with Bimorph nodes
Secondly im calling the pipe type, i want to obtain the existing Sanitary in this scenario
Third im doing the same with the system type
And lastly i am using the node to create the lines to pipes but it gives me a null resutl
Hope this is clearer for the understanding of everybody
Thank you
Check your input type for the lines. Looks like you’re feeding a point instead of a line.
Glad it helped. Please mark a solution so others can learn by reading.
