First electrical network model – Questions about bends and topological modeling
Good morning everyone,`
First of all, I want to thank those who designed this program—it is truly excellent. I've been using it for a short time, but I've found it to be outstanding.
I'm working on my first electrical network model and I have some questions regarding the modeling process. I've read several specific threads that have helped me a lot in understanding how the electrical network works.
1. Issue with bends/conduits:
I'm having a problem with curved conduits, as discussed in this thread: https://community.osarch.org/discussion/comment/27890?
The solution provided involves a kind of workaround that worked well for me. In my case, I'm using PVC conduit with a bend radius of 0.102 m and approximately 0.02 m straight segments at the beginning and end of each conduit. However, when I reopen the file, the conduits disappear.

But if I create a new one with modified dimensions,


Hoping to clear the error, and then recreate it using the multi-object selector, all the conduits reappear.
Note: The fact that BB (BlenderBIM) can automatically generate bends is really very practical and saves many hours of work. In my limited experience, placing MEP fittings intersection by intersection, rotating and positioning each one manually, plus adding ports and connecting them, is extremely time-consuming.
My question: Can the parameters for Add Bend be edited somewhere to standardize them for ½" conduit (or any other size I might need) in my projects?
This would also be very useful for Water Supply and Sanitary Piping systems: being able to select a fitting and have BB automatically align it and create the necessary ports would be excellent.
2. Regarding Topological Modeling of the network:
I have several questions. For cases involving multiple switches, I'm creating several sub-circuits within a single circuit, where each one corresponds to a switch or sensor controlling specific lights.
My doubt is: if I assign the corresponding elements to each switch, do I then need to re-select and re-assign them for the distribution panel's general circuit, and again for the main electrical panel?

I've attached the file and look forward to your feedback. Thank you very much!
