How to change 3D orbit reference?

[Anonymous]

This has bothered me for quite some time in Inventor. When i rotate my model/assembly in inventor using SHIFT+Mouse wheel the object rotates around the coordinate axis location unless i physically click on a new reference part or geometry. This was always very frustrating to me because in other applications from Autodesk, specifically AutoCAD, 3D orbit/rotate always picks a rotation reference based on where the mouse is instead of rotating around the global origin. What i want to know is if there is a way to change the orbit behavior so it is more like AutoCAD thereby, orbit uses my mouse for the reference rotation center?

Hi Tigs,

with orbit reference do you mean the rotating Pivot?

When you normally orbit Inventor doesn't use the coordinate system but use the geometric center of gravity of the part/assembly as rotating pivot.

You can temporaly change it in these ways:

1- Using the streering wheel tool

2- Click F4 key. Click on the part where you want your new Pivot. That's it.

To restore geometric COG pivot just double wheel click.

How do I change 3D orbit reference on a 3d sketch?

I have survey points that has an origin 100's of metres away, I'm sketching on the 3d points and cant find a way to pin the 3d orbit centre to a point on the 3d sketch , ...... the sketch shoots off the screen.

Hello

Is there a way to turn off the automatic changing of pivot point when in perspective view? I'm using F4 to get the pivot point how i like it, then i zoom and maybe change the view angle, and it automatically pics a new orbit point. It's so frustrating to keep picking the same orbit/pivot point because of the auto update.

Sorry for "hijacking" the thread. But can't seem to find a solution.

Best regards

Hi Marin,

If I understood your request correctly, Constrained Orbit might be the one you are looking for. Click on the downward pointing arrow button under Orbit button. Select "Constrained Orbit."  In this Orbit command, the focal point is locked in a place. It would not spin out of control.

Many thanks!
