View jumps when panning

[r_kammingaGASBX]

Hi all,

I'm working on a rather large assembly, and have issues with orbiting/panning, in combination with a 3D mouse in large assemblies specifically.

Often, as soon as I touch the 3D mouse, my view skips a couple of metres, but often to the exact same coordinates. This only happens when i am working in certain areas of the factory (complete assembly of the whole plant). It also often happens after the same series of movements. e.g. i'm in location XYZ1, pan to the left, then orbit to the top, and as soon as I orbit, i jump to location XYZ2. But, if I repeat my inputs while on locatoin XYZ2, it doesn't jump. When I move back to roughly XYZ1 and give the same input, i jump again. But if i orbit in the opposite direction, nothing happens. 

It's jarring and infuriating, because orbiting takes 10x longer than necessary, due to me having to reorient myself all the time, and then having to navigate back, just to have it happen again.

No, it's not an issue with the 3D mouse, i've checked doing the same inputs in various other programs.

Is the 'plant' bigger than 100 meters in size?

Inventor has a limit of 100x100x100 meters for a model, after that, strange things start to occur ( 101 meters would be OK, 5000 meters would be as in issue )

[r_kammingaGASBX]

Ah, ok! Yes, it's bigger so that would be a logical explanation. About 190m long, 140m wide and 35m tall, with about 130 separate machines, but all simplified to about 40-50 parts per machine. Thus total would be 6500 .ipt files at most. The longest single (simplified) model is rougly 50m long.

Do you know if later versions of Inventor have solved this limitation?

It looks like this is an assembly you should use Navisworks to look at. Inventor may be suitable for assembling it, but I would strongly recommend using a more appropriate clash detection and visualization application.

Inventor still has and probably will always have this engine limitation of 100x100x100m.

Definitely agree on that we should use something different haha, unfortunately the company developed all kinds of plugins for Inventor, forcing me to use it.

Hi! Just to clarify, the valid model range (+-100m in each direction) only applies to geometry (mostly in a part). For an assembly, the range is much bigger.

Many thanks!

Okay, so the model range isn't an explanation for the view jumping then.

Has anyone else had this experience, and solved it? I've tried playing with view perspective modes, running express/full mode, reinstalling the 3D mouse drivers.

I've noticed that my mouse is offset as well. If i try to select a model, i'm selecting something a few metres offset. This offset seems completely random, but related to my zoom level and angle.

Hi! I am wondering if this registry key could help. Please take a look.

Many thanks!

I've made the registry change, but I don't notice any changes in behaviour. So I'm not sure if I have done it correctly. The view still jumps at the same coordinates, to the same coordinates. The framerate is a lot higher though! Before the change I had about 2-3 frames per second, but now it is definitely >=30. The howto didn't mention anything about that, but it's very welcome. I can even run Navisworks (old drawing for comparison) and Inventor (new drawing with plugin data) at the same time, both running with good framerates. This in itself has accelerated my work quite a bit. We can't use two Inventor instances simultaneously. It freaks out the homebrew plugins from our IT department.
