Can't find part: FET MPF102 or 2n5457 or compatible

Yeah. Unfortunately FZ is not well supported, so we constantly have to make do with whatever we can.

You are not wrong about svg drawing - it’s closer to CAD than raster -, and it took me a couple of years to know enough to get by.

If you’re interested I did a series that teaches you vector drawing as well as FZ part making in the same video, which is quicker than learning both separately.
