I recently had a reader reach out and ask if is is possible to place Spot Slopes on every face of a Floor with Dynamo. Though there are no nodes (both ootb or custom) that I know of that will place a Spot Slope, you can still achieve a similar result by calculating slopes and putting those slopes into Generic Annotations.
This method can be used to place any number of symbols, annotations, or even detail components in a specific view.
To complete this definition you will need both Landform and Clockwork.
Since it has a few moving parts, I’ve broken it down into groups that explain what each part is doing. The bulk of the definition (the two green boxes on top) are simply rotating the annotation correctly in plan (xy).
Here is the result in Revit:
When working through the definition, I also placed actual Spot Slopes on each face in order to verify that the slopes were calculating correctly. Here they are in tandem:
As you can see, the generic annotation does not always have the text oriented correctly. I assume that this could be corrected fairly easily by filtering for certain angles and using one of the several flip nodes available in Clockwork.
