I glanced at two reels... one doesn't have the capacitance value called out (just has the manufacturer's part number that has the value embedded within it), another says ".100uF", which I'd suggest is poor because it's only a
+/-10% capacitor so they have too many significant digits and should start with a leading zero anyway ("0.1uF").
So as I say, different manufacturers do it differently...
I'm not quite sure what you're responding to, but drawing wires that cross at right-angles using a little "loop" to indicate there isn't an electrical connection between the two is a perfectly reasonable practice.
I don't think it's tacky, although I don't think there's enough benefit anymore (especially with most everything done electronically these days -- few hand-drawn schematics) to bother.
I briefly had a subscription to Elektor magazine while in high school at the time the schematics were straight re-prints of the English version and used "12k6"-type notation. Eventually they started re-drawing the schematics to "Americanize" them, though.
A lot of drafting standards came about due to the limitations of technology some 50+ or even hundreds of years ago (e.g., all upper case text); with design entry being done electronically today, a lot of those standards deserve re-visiting, if only to realize that today many of them are "standards for the sake of having a standard" (which can be a good thing) rather than "standards for the sake of preventing some very real problem."
At one place I saw an entire batch of boards get shipped (in product) that were stuffed with 47 ohm resistor networks (marked 470) rather than the correct 470 ohm resistor packs (marked 471). The previous supplier marked them "470 ohms". Best regards, Spehro Pefhany

I was out of town during the messy part. Lots of ash and charcoaled leaves and twigs ended up at work, 3 miles from the fire. Following link are photos my colleague took from work.

The populated areas were spared, only because they were able to stop the fire along orchard edges. We also had very forgiving weather patterns during the major part of the fire. This fire is a blessing in disguise - it has now cleared the hills of the 50 years of accumulated fuel which means Goleta is now safe when the big Santa Ana winds hit. We have total mismanagement of our front range. Idiotcrats refuse to do controlled burns on the front range so they end up with $10M bill instead of a $200k bill. Santa Barbara city front range hasn't burned for decades and the potential is there to wipe out thousands of homes in one big fire event.
Our next threat is mud and debris slides if we get a few big rain storms in our coming rainy season.
You can thank the leftist weenie liberal greenies for preventing controlled burns and clear cutting.
It's going to take a national disaster to get people to wake up and take these crapheads out. Maybe gasoline and food prices will do the trick ;-)

This isn't a leftist weenie issue. Babbitt, Secretary of the Inferior during Clinton's reign, was all for controlled burns.

Clear cutting isn't an answer either. It promotes mono-cultured forests which creates problems of its own (disease/blight). If done right, it's fine.
It's weenie government agencies needing to execute potentially dangerous activities. If a controlled burn gets out of hand, then heads roll. It's happened in our county. Much easier to sit back and fill out paperwork than to execute difficult actions. The way things run around here, filling out paperwork & smoozing gets them promotions. Government employees who do real work and don't fill out paperwork, attend meetings and political social events are forced out. This happened with our arborist for the city. It's happened with friends who worked for the Forest Service locally (one case went to Federal Court, the other person was given early retirement to keep his trap shut about his superiors' illegal activities). Now we have a weenie head arborist for the city who never looks out the window at the trees he's supposed to deal with. He does a fantastic job of filling out paperwork.
Babbitt, one of Arizona's worst governors, has no balls to administrate anything.
Before the greenies got control here in AZ the loggers did selective thinning. Now there's virtually no logging in AZ.
We need a return to the guillotine ;-)

It\'s what you learn, after you know it all, that counts.

I mix'n'match depending upon my preference at the time among other things. "0u1" can be handy for those compact schematics where designator space is at a premium. Quicker to hand write on those back-of-envelope schematics too.
Once one gets up above 0603, one may find markings on the caps. Said markings are very faint, and appear on the base substrate, between the terminations. Typically a two figure designation, such as "A3".
Thank you for laying down the facts as you see them - however, when you grow up and gain more experience, you may come to realise that diffferent conventions may work better in different circumstances.

It won't happen IRL either. They get designated as 1262 at three significant digits, and there is no way to confuse the value because it only matches a real resistor value when read in one direction.
You are new here. You are arguing with one of the many aliases of Dim Bulb. It is a major time waster. He is always wrong but burns up a lot of your time yelling and stomping his feet when you point that out to him. You are best off kill filing him.
Ok, was doing a little studying, and found that Altium CAN display little loops over all the non-connected intersections. Don't know if you can EDIT in that view yet, or not. Will do more research!
