I've modified railing families before to create custom patterns, however I'm having trouble with this type since (I think) the profile of the balustrade is not symmetric in the plan orthogonal with the length of system.
i.e. when I created the balustrade (in the shape I want), the following message appeared and the balustrade got deleted:
An error occurred in family and was automatically resolved, but may require review by the family creator. error information: "the constraints of the sketch defining the highlighted element cannot be satisfied." error resolution: delete element(s)
See photo and Revit family attached of the balustrade I created.
Thanks.
