Now with dynamo I am hoping to build in some automation. A perfect world to me would be if dynamo can get a list of loadable families within the project and write that list out to excel. In excel I can get a mapping done that if it sees one family it replaces that one with the new family (I kept the same Type name within old and new family). Then dynamo reads the new excel file and replaces the family with the new one keeping in mind I want it at the same location, same rotation and same type within the family.
Where I am at now is, without using excel, I can select a group of old family with different types and swap them with new family keeping the same insertion point and the same family type. I am hitting a wall with keeping the rotation the same. I am working on that though.
