Is it a bad idea to use 2 vias to change layers in power tracks?

I have some power traces (net VIN) in my PCB design that might (in an extreme scenario) carry up to 1A of current. Although nominally, I wouldn't expect to see more than 250 mA. These are 50 mil traces, just to be safe, and since I have to switch…

How do I disable clearance check for a layer or for only some certain elements?

I'm designing a PCB in Altium Designer. There is a very large heat sink in my project. When I put it on the PCB, there will be plenty of empty space under it where I can put other small components. I tried to put some part of this bridge rectifier…
