This is what's happening in an unpredictable fashion in my workspace.
When I navigate to something else, I can expect the disappearing polygon scenario half of the time.

Hi halmi,

To avoid that you need to set the rotation pivot point as described above.

When you want to orbit around a particular object, select it and push the "Reset" button.

If you want to work closely on a small area of an object either select an edge or face in that area and push Reset or use the Area zoom button to snap on to a specific point.

In your video the problem is that you're not using either one of those methods.

Hi halmi,

you can also set the script for quicker access to reset view:

Why don't use the icon Rotate ?

Click edge : Reset then Icon rotate

Thanks for the replies - I do use all the tools suggested, but I was hoping to add pivot automation to the mix. If I'm moving around a lot and working on a bunch of details, I become very aware of the extra steps. The area box is a pretty cool tool when I want to jump to a distant area and work on it, but right now I want to simply zoom seamlessly to location and just orbit at will. Using the box or reset usually throws me abruptly to a different position, where I have to make adjustments to return to where I was. And with reset, I have to make sure to deselect anything other than the intended object and select that. And after a few minor movements, I lose that pivot point and have to do it again.
Is it possible for the rotate camera command to select any hovered object as its pivot point? In any case, this is just wish list stuff. I'll try to create a video to illustrate why I would like it so much - but it's not at the top of my to-do list - continuing to design is. Thank you for your patience, Michael.

Hi halmi,

re:

It's difficult because MoI's view system is designed so that the 3d view is always centered on the pivot point.

If the pivot point would relocate on hover, within the current system the view would be jumping around a lot as you hovered over things.

So doing that would require some pretty substantial changes to allow the pivot point to not necessarily be on the center ray.

Ah. That explains it. How about only when the command is initiated? Hovering alone wouldn't be enough. Would that limit the abrupt view shift only to the Moment of Initiation? Or...can the box or reset have the ability to simply center an object in question (selected/hovered?) without zooming in or out?

Hi halmi,

I guess so, it sounds pretty weird though.

You can try setting this up on a keyboard shortcut, it will set the pivot point to a point you pick without doing an area window:

script: /* Set 3D view rotation pivot */ var p = moi.ui.createPointPicker(); if ( p.waitForEvent() && p.event == 'finished' ) { moi.ui.mainWindow.viewpanel.getViewport('3D').targetpt = p.pt }

Thank you so much - I'll check it out, and you may be right...
...and I like it. I tap the shortcut key and click the location, There's a shift, but it's not a huge leap, and I (camera) am still pretty much where I was. I also just I took a dive back into my expired trial of Rhino to see how it was done there. They have a button called "place." Guess what it does? That's right! Except the shortcut is faster (and seems to perform more consistently) in MoI.
