Hi everyone, I design 1 specific graph for 1 project. The Dynamo graph supposes to create 5 generic model families from Solid Blocks that were created in Dynamo (the intention is that when I change the solid block’s shape in dynamo --> the family instances’ shape in Revit will change accordingly) Then add the shared parameter for these family instances.
First run, the graph worked fine. As indicated in the photo below, all 5 blocks had expected shared parameters and desired shape.
Now here is the problem:
If i would like to change one of the family instances’ design from a rectangle block to a chamfered corner block and run the graph again for update. Each time Dynamo deletes all the shared parameters that I added from 4 other blocks. Dynamo only added the parameters of the block that i changed the shape.
Do you know what was the problem here? Is this element Binding Problem ? I thought Dynamo would override all elements and its properties on top of old elements which were created within this graph? Means, shouldn’t all of these family instances have their parameters and new design shape each time i run the code?
I had this idea from Jacob Small’s video below, please fast forward to minutes 13:00
