transformation and placement from X/Y coordinates into polar coordinateds and creatiion of property lines is the goal.
I am using Dynamo 1.2 and revit 2017.
I have x/y in Excel.
I wanted to draw property line into Revit with those data.
First I read the data
than translate into a well defined point as origin.
Than I was trying to rewrite the excel data.
than doing an operation to transform into polar coordinates since Revit accept only those for property lines.
Unfortunately I got the “Null value cannot be cast to Int32.”
Do I have tro transform into string the data before writing to Excel?
