Orbit and geometry randomly become inverted frequently!

Orbit and geometry randomly become inverted frequently!

This has been an on going issue for me for at least a year. It doesn't matter what machine I am on. I have a 3DConnexion Space explorer mouse. Randomly when orbiting a model the geometry becomes inverted. The origin flips sides and all motion is reversed. I feel like I'm going to have a stroke when this happens! If I spin the model around more it will go back to normal for a bit. It doesn't matter if I move with the space mouse or the regular mouse using the middle button. 

 

I have attached a screen cast which starts with the origin incorrectly inverted. I am rotating the model with the space mouse. You will see to origin appears incorrect on the top side of the model and again on the back side. I am having to move my hand opposite to what my normal controls are. Once the model passes orthogonal to the XY plane the model magically goes back to normal. Sometimes it takes many rotations before things are back to normal. This is happening often enough that I'm about to quit fusion. It destroys my flow.

Hi @joseph.wrenn.frederick ,

 

Thank you for posting in the forum! Personally I haven't seen that issue and am having difficulty reproducing it.

 

Is that issue reproducible? Do you know the steps that cause Fusion to behave that way?

 

Also, does it help to click on the view cube in the top right corner to fix the issue?

It is very reproducible. I haven't noticed anything in particular that
causes it, but it happens many times an hour. It doesn't matter what
computer I'm on or what model I'm working with. It occurs even on brand new
designs.

Originally I thought it was a graphics card issue, but it happens on my
surface pro 3, my lenovo yoga x1, the same x1 with an eGpu GTX1080, and my
regular desktop pc. I only use the space mouse with the x1 and egpu, so it
isn't a space mouse issue as it happens on the other computers as well.

Hi @joseph.wrenn.frederick ,

 

Thank you for your response! 

 

I'm sorry if I'm missing something obvious but I created a similar sketch and tested, and now I'm not very sure if the origin is actually inverted in your video. It seems like the origin matches the view cube, and I thought it may look inverted but it's actually not.

To verify the behavior, if you create a box at the origin and rotate the view, does it still get inverted?

It would be impossible to tell with a box because the model geometry is
inverted as well. For example text on the top surface of a model becomes a
mirror image but still appears on the top because the geometry is inside
out. I will try to screen capture a box with text to indicate the axis
positive direction so you can see it flips. I realize it is hard to track
visually only, but it's supper apparent when the controls spin the model
the wrong way. In my linked video the origin flips from the top of the part
to the bottom, but without knowing the part it's hard to tell.

I have been so frustrated with this issue in fusion that I hadn't been using it for a while. I started up again today and have indisputable evidence that the geometry and origin flip! I modeled a rectangle (not a cube so we can better see it flip) and left it visible in my sketch. I zoom in on an area where I am working and my controls flip to be reverse. I appologize for the crazy motion as I have a ton of trouble when everything reverses. 

 

You can clearly see that "TOP" is backwards but on the top of the rectangular prism with 14 seconds left in the video. The origin is aligned with the faces of the rectangle which is reversed. I flip around ridiculously some more and lo-and-behold the "TOP" is now the top again! This is insanely frustrating!

Hi @joseph.wrenn.frederick ,

 

Thank you for the update!  I had a look at the screencast, and it seems like you were looking at the model from the bottom/left when you thought the origin flipped?

I was able to recreate something similar to what you are seeing and recorded a screencast of that. It can be fixed by clicking the view cube in the top right corner. 

 

Hopefully that helps!

No. Look more closely around 14 seconds remaining. You can clearly see the
word top is reversed but attached to the bottom surface. Everything in view
is inside out. I realize it's difficult to see, but it is really easy to
notice when everything suddenly starts spinning reverse. I need to finish
this model so I guess I'll keep grabbing screen casts until one is so
obvious it is undeniable. I'll change the rectangle model to an arrow so
you can see the text will run the wrong way when it inverts.

Can you test with a solid color, not see-through? Also, have you tried clicking the view cube in the top right corner?

I have mostly noticed this behavior in the sketch environment so everything
will be transparent. I can't just fiddle around to convince you as I have
real work to accomplish and this issue is making it severely difficult.
I'll keep trying to capture as I work it so it's blatantly obvious, but
even if you can see what's happening I don't know how it can be fixed. It
has happened in CAM as well which is also obvious to me because suddenly
tools are cutting on the wrong side of the part! I haven't tried clicking
the view cube. Honestly that doesn't matter to me as I'm using a space
mouse. When I pivot the space mouse right and the model suddenly goes left
instead because it's inside out it is very disorienting.

This happens using touch to rotate models on a surface pro as well.
Entirely different computer and entirely different models.

In my preferences I turned off "activate component visibility" under design and now I don't stroke out anymore!

HI, 

 

I experienced the same problem. I understand how difficult it is to explain. But, you're correct it is very difficult to control the model when it happens because your movements are inverted. I also think that when this happens the origin remains the point of axis even when I select an object to pan around. Movements will still match the cube, but the model twists in the wrong direction.

I don't know if it will fix your problem but I went into >preferences and changed >default orbit type to >Free Orbit. It worked for me, maybe that will work for you too. Or anyone else, since this post is quite old and you've probably rectified it by now. 

 

Thanks.

Yes this is an issue. Not sure how to fix it. Very obvious when it happens. Watch old mates videos. You can clearly see the object not matching the home cube.

Behaves the same way in Revit 2022 . very annoying.

Was there ever a solution to this? This is happening to me and has been for over a year. I have tried just about everything!

Yes Im experiencing the same. Especially when I turn the object to close to the ground it flips the whole object and view cube shows view from the botttom.

This just started on a new project where it is a lot larger model than I'm used to i.e. my object is far away from the Origin.

Any progress on resolfing this?

I think it’s just an optical illusion. Left and right side of the brain
kind of thing.

No I assure you, it is not. When it inverts, the SpaceMouse controls are completely opposite of what they should be. Here is a video to show it inverting. In the very beginning of the video the orbit has just reversed, and you can see that the viewcube says the top of the canvas of the pigs is on the Bottom of the view cube. Now after I wiggle it around for a bit, you can see at the end of the video that the viewcube is now saying that the top of the design is the top of the pig. The axis keeps flipping and there doesn't seem to be an answer to why. I just want to fix it.
