Workflow optimization using Dynamo

I've created a script which is my first attempt using dynamo to improve modelling workflow.

1. Challenges: Situations when a modeler is required to shift across different services ranging from HWP to Gases or even between different disciplines like pipes to ducts.

2.Why not to create one more Filter?

Filters are effective but there may be situations when you what temporary isolation of few elements just to enhance drafting or modelling feasibility. I prefer not to create too much of filters cause it might be a mess with a lot of filters and conditions.

With this script I can now easily shift across different services just by selecting all elements in view and I've set condition to isolate particular elements to be displaced and that too temporary isolation, "coz conditions might change in future".

Feel free to comment on the script, will optimize if required. :)
