Hello guys!
I am learning Revit and Dynamo recently and not yet understaning all things.
My task to make script for drawing electrical scheme in Drafting Views of Revit.
I have Excel sheet with family names and values shared parameters.
I take it from Excel and try create family instance with parameters.
The family name from Excel is string and I use node “Family.ByName” for create Revit family name then I get family type (use node “Family Types”), transpose it and applyed node “FamilyInstance.ByPointView”.
But appeared message “Dereferencing a non-pointer”.
Where my mystake?
Could you tell me please.
Thank you in advance.
Andrei.
@AndryGrey Please re-post your graph we can’t read. Use camera button (top-right) built into Dynamo - it screenshots the entire canvas.
I tried take photo of script a few times but quality is low and it don’t readable.
I uploaded files to cloud, you can download it from here:
I understood why I could’t placed families on drafting view.
I try to send list of Family Types to node “FamilyInstance.ByPointInView”, but this node is working with only one Family Type.
I changed my script and script is allowed to insert two Family Types with three parameters by points.
But script get very big.
If I need insert ten Family Types with ten parameters then script will be huge.
May be somebody know way how optimize this script.
Thank you in advance.
Best regard
Andrei
