A Revit vector property is different to a Dynamo vector ‘object’. Dynamo can work with Vector objects to determine angles and so on. This node takes a Revit vector property and tries to make a Dynamo vector from it.
This node takes a point list from the Revit API (feet, XYZ), and creates actual Dynamo point objects. It allows you to input a scale. To convert to mm, put in 304.8 for the scale.
