I have a need to error trap a null set.
I am reading in spreadsheet data that describes the points and profiles for a 3D sweep. There are 2 types of profile that can be used in the sweep. (a circle, and a flat or filleted rectangle) The incoming list can have a mix of designated type or only use one type of profile depending on individual circumstance. Therefore, I choose a Boolean mask to expose the round and flat types.
The problem comes in when one or the other profile type is exclusively chosen for a given design. The boolean mask then returns a “full” list for one type and a empty list for another type. I would like to capture the errors prior to passing on to a node failure. I’m not too sure the node failure is actually a “bad” thing as it’s a failure and no geometry is created. 8^) However, I don’t think it’s a good practice.
please see the node map below and I have added a closer look at the nodes that perform this task. Thanks in advance.
