Any PC that has virtualization features can be used. Unless it’s very old, I’d say it’s supported. But it may not be enabled in the bios by default. It’s called VT-x for Intel and AMD-v for AMD, I think. But both are supported for at least 10 years on almost any PC.

It’s a hypervisor level virtual machine host and you can use it to install multiple os’s on the same machine with little overhead. I’ve been running haos like that for a few months now and I’m super satisfied.

There is indeed multiple ways of doing anything in freecad. But over time, I prefer staying in Part design as much as possible as this makes it more modifiable and customizable and there are plenty of reasons more for me. But in the end - whatever works is good enough.

Shape binder is what you need. Shape binder can be used to reference geometry from another body. What I would do is I’d make one pocket on the main body. Then select another body and make it an active body. Then select the pocket you made (the surface or the edge) and create a shape binder (part design). This will effectively import the selected feature from the first body and you can reference it from second body. Make sure you hide the first body, as it somehow gets in the way of shape binder, for some reason. Repeat for third body.

This seems like the best option for my country. They are easily available and seem cheaper than Reolink. Do they have free API for all the smart functions as well? Like movement detection etc.

I have a newer ZigBee 3.0 dongle and run a few add-ons, but nothing big - z2m, nodered, mosquito is all I use. I will upgrade anyway, but I’m not in a hurry, it works fine, apart from an occasional delay in switching, which might be network related.

When you switched from pi3 to NUC , did you notice any performance improvements? I’m asking because I run my setup on a rpi3 and it mostly works ok, but the latency is sometimes high, so I’m wondering if upgrading the host will improve things.
