This is one of those things you don't think of until you need it. Wanting to rotate something around a specific point can be problematic in certain circumstances.
In this example you can see the whole group is off-center from the wanted rotation point and the normal rotate tool can be difficult to position on the very center. So by opening the group you can select all the groups and components and use the Move tool to rotate them all using the Wheel component's rotation handles.

To follow on from Rich's comment, it sounds like you have the download dialog set to 'Open with' rather than 'Save File' You need to set it to save file to get the RBZ to your computer to then get the extension manager to use it.

Oh, ok, for me it is enough to put me off using it. Perhaps just a white circle of background around the pie itself so you can still see the rest of the model. A separate toggle would be good.

I'm curious too, what commands is it set up to use. I know in your user guide you say it won't show ones without a button, but I noticed some are missing that do have a button. The most obvious example for me being the Lasso tool.

A more useful tool than I expected, I've got so used to using my custom toolbar I thought it wouldn't help me much. But I can create a variety of mixed toolbars, a bit like using sets, so I can have some specific plugin tools easily available. Very handy.
I also thought, since I generally use a stylus and spacemouse that having to hit a keyboard shortcut was sort of defeating the purpose. I have the space mouse buttons set to shift and ctrl and the stylus has click, double click and right click, so no combination of them could activate the pie. I thought the Gesture option in settings would help here, but no.
Finally dawned on me to set a shortcut and assign that to a gesture in my tablet settings and sure enough a simple finger tap and I have the pie without needing a keyboard. Excellent.

The only downside I have at the moment is there appears to be a bug, at least in my system, activating the swipe option in the pie settings actually sends the screen opaque. So when you activate the Pie the screen is white with only the pie menu visible. So something is causing the transparent background of the menu to fail. I have restarted both SU and the PC as a first step to troubleshoot.

Making quick work of what would be a tedious job by using solid tools.
I've used Split, but Difference is all you need if you just want the grid structure.

Or tick the box for, 'Disable pre-pick on Push/Pull Tool' found by going to Window/Preferences/Drawing

I've recently posted a couple of non extension thread techniques elsewhere, in truth tho they aren't really true threads because they have multiple 'paths'. So I just did this one for the hell of it, mistakes and all, and thought the best place to hide it was here.

Oh, Ok, looking at the background of your image it isn't in what would normally be referred to as an electronics clean room. Computers are dust magnets and dusk is one enemy of electronics. Your pc case has open slots and significant evidence of dust inhalation. I'd be putting it in an enclosure myself.

I'd also recommend that if you really want to keep the pc in the workshop, build it a cupboard. Roomy and with filtered ventilation so the whole thing can breath without sucking in sawdust. A simple box with a door so you can access it to turn it on etc with cloth sides so it gets air. Do the sides with velcro so you can easily remove them for cleaning and access to and for cables etc. This won't keep everything out but it would certainly help.

It's pretty simple in layout.

My mistake, family friendly site, should have posted this version.

Here you go, the Brutal David.

Surely the ipad has a context click option, tap and hold for example?

On my facebook page ( https://www.facebook.com/BoxGifs ) you can pause them by clicking them, or if you go to the vid section of the page all the gifs are there as videos so you can go back and forward on those. But the ones here in the forum are generally very short, or at least that was the idea when I originally produced them. Short and to the point.
John, aka Driven created a gif player for use with my gifs within sketchup, but he seems to have disappeared off the face of the earth and he didn't release it.
There are gif players out there but I don't know one to recommend.
Some of my gifs are loaded here from imgur, all the ones on this page for example, and if you right click and choose Open in New Tab you will get the gif with player controls.

Try this one. I made it for a thread but got distracted for 3 seconds and Dave and Rich answered.

I know Baz, people often ask for vids rather than gifs, but vids are a pain. You have to record them then upload them to youtube with all that that involves then paste the link back here with the right bb code.
Gifs, make em, drag to screen, done.

You won't accept anything that you don't understand. Don't worry I won't waste my time doodling anymore in any of your threads. But you can benefit from all my replies none the less.

Just wanted to test the youtube embed.

One of many possible uses.

The ability to tap a shortcut, click a specific spot on your model and proceed to add geometry that is already contained within a component that has the insertion point already assigned is an extremely useful feature. But I'm sure nothing anyone says will convince you.

Make the component before adding any geometry.
