TL;DR

Display radar coverage preview when placing a blueprint that contains a radar.

What ?

Placing a single radar (ghost or not) shows a blue preview of its coverage on the minimap (top right) - it is useful if you want perfect coverage without overlaps - but when you place a blueprint containing a radar this preview is not shown.

Basically it was already reported as a bug but it was explained it is not a bug but a limitation in order to optimize performance, even if I don't think radar is an item that is usually present in multiple copies in a blueprint.
In OT it's also suggested to adopt the same approach used for turret range blueprinting, with an explicit option for toggling it.

I hope it's acceptable to repost the request here, in the suggestions section, in order to avoid it being lost in the "not a bug" section.

Why ?

Basically, QOL, because right now you can obtain the same exact result placing the radar first (coverage displayed) and then placing blueprint.

similar, but just for roboport coverage.

Please show the blue radar range square for radars in blueprints (and copy/paste) when placing.

Noting that this is highly difficult if the paste / bp contains multiple radars.

[Koub] Merged into older thread with same suggestion.

Thanks, Koub.

I have a blueprint which contains a radar, several solar panels and accumulators that will keep it active fulltime.
Placing it however, will always have to done in two steps, radar first to check the coverage and then the blueprint afterwards.
As mentioned, this is just a QoL thing.

@JasonC, you mentioned "this is highly difficult if the paste / bp contains multiple radars" but is that not also the case with roboports then?

You mean if the paste contains roboports? , probably! I don't have a lot of pastes with roboports; but if roboport connections don't show in pastes then they probably should be shown, too!

Btw, I also have one of those little radar outpost bp's, that's actually what prompted me to make the suggestion, haha. I've also got a bp with 2 radars spaced a radar range apart that I use a lot too, to make covering large areas easier.

And actually, btw, my solar/radar bp has landfill tiles in it, which is another case where the "workaround" of placing the radar first isn't that great: You can't place radar ghosts on water, so you can't place the radar first without dropping landfills, which is kinda extra inconvenient.
