Model disappearing when orbiting

[junderwood]

I am having an issue where my model in Navisworks disappears, or zooms so far away that is becomes difficult to get the model back into focus, because when zooming back in it zooms WAY TOO FAST.  I understand that is because of how far away the model is.  My question is, what is causing this in the first place?

This happens when I use the scroll button + SHIFT key to orbit the model.  The only thing I know to do at this point is close the program out completely and reopen it to find the model again at it's save point.

Option 1 : Before to append the model open it in the software where you created this model. Filter and remove or purge unwanted block, lines, text and other object from the model. Now open a new session of that software, copy the entire model, paste at original cordinate in the new session. save it, and now append the model in the navisworks. Hope it will help you. if not follow the option 2 below

Option 2 : before appending the model in navisworks, go to viewpoint tab beside home, go to Render Style, Click on points, lines, Snap points, and text to off it (do not click on surface otherwise entire model will be off). Now select any specific system from the model and right click, then click "Focus on Item"

and check with orbiting. 

Let me know the status after using above tricks.

It has to do with your viewpoint (defauts)

Right click on the background -> Viewpoint -> Edit current Viewpoint

there you can set your Linear speed to something like 5 m/sec and angular speed to something like 30 deg/sec.

Other than that, before using orbit,

Aways select something -> right mouse menu -> Focus on Item

(If your whole view is inclined, than use the foots to set just one step back using arrow down on your keyboard)

and then start orbiting.

I tried your suggestion with the Viewpoints.  I am working with Imperial measurements, but in any case, it was already set to 11 ft/sec.  The Angular speeds was set to 45*/sec, so I adjusted that down to 30* as suggested.  Still not working.

I do know about selecting an object to orbit around.  That is not working either.  It's less often, and less extreme, but still not a solution.  Thanks though.

This has never been a problem for me before.  This is not a model that I created.  It is a model that I am using to coordinate MEP rough-in with, downloaded from the general contractor share point site.  It was provided by the architect of the project.

There’s a temporary solution to overcome this “Extreme extents” issue and get your model back into focus :

1. After opening your model right-click the home button on the view cube, and select set current view as home view from the context menu.
2. when the model disappear, Click the Home button or select Go Home from the context menu to display your saved home view .

I know this is not the perfect solution, but at least will save you the need to close/reopen your file.

@junderwood

Sometimes this works:

Go to "file options" <shift + F11> and change the near clipping planes from automatic to fixed with a distance of 1.

If this fixes it, one of your models has objects somewhere out in space.

I had thought that my model, or the architect's model might be out in space somewhere.  Your suggestion did not correct the problem though.  Is there another way to tell if the models are not aligned properly?

[junderwood]

@pinaki.rajak  The model is provided by the architect of the project.  I've never encounter a problem like this before.  So turning off lines  in the Revit model seems unnecessary.

I did try to make the suggested adjustments in Navisworks before appending the model.  Those options are not available to me.  Perhaps because I am using Navisworks Simulate instead of Manage.

[pinaki.rajak]

The options are available in simulate also. Anyways, Can you please share your nwd model to me? I would like to check personally for any solutions.

[junderwood]

I've attached the file below.  Additionally, I am having a problem not being able to view my appended Revit model inside the the Navisworks model.  I know it is there, because it is in the selection tree.  And, if I select it I can see the Revit model, but not the Navisworks model.  Similarly, when viewing the Navisworks model, none of the Revit model fixtures can be seen.  Thanks in advance for your help.

[pinaki.rajak]

Done !!

Your Revit Model's location (X,Y,Z Points) was far away from your Navis model's actual positions. and it was the main reason of disappearing and non-visibility issue. I have adjusted your Revit Model near to your Navis model.Now all of your requested queries are resolved.

Only one issue : not able to match your Navis and Revit Model together as there is no such coordinate point found in your Revit model to match with grids of Navis Model. Hope, you can address this issue by yourself or this coordinate point issue can be raised to your client as well.

Collect your updated model from the attachment.

Let me know if you happy

[junderwood]

Well I am happy that you corrected my mistake.  Thank you very much.  I am curious, what I might have done wrong.  I believe it might be possible that I shifted my Revit model prior to pinning it down.  Is that it?  If so, how can I correct it without having to start over?

[pinaki.rajak · Accepted solution]

Yes, Revit Model was not in the same coordinate point (X,Y,Z) of your Navis model. Before to append it in the navis you should check that, are the files are in same coordinate point or not. If no, better to adjust in Revit as well rather depending on Navisworks considering accuracy.

In other hand, If you need to resolve coordinate problem in Navis itself then you required a common intersection point in both the model, like grids, common columns, building corner etc. by which you can measure the X,Y,Z distance by measure tool bar from 1st model grid intersection point to 2nd model's same grid intersection point. After that according to the measurement value you have to transform X,Y or Z position of dislocated model to match with proper located model.

But I don't like this steps at all as there is chance to inaccurate re-positioning and also someone might mistakenly reset the transform by doing reset all. then all the adjustment will be futile.

You are welcome for any kind of support on AutoCAD, Navisworks, Revit & Fabrication CADmep.

So how do I make this adjustment in Revit?  How do I even know where to begin, when attempting to align the two models?  I ould think I would need to find out the (X, Y, Z,) coordinates of the linked model, and then adjust my host model to those coordinates...  I have already removed the linked model, and then reloaded it into the project using (ORIGIN-TO-ORIGIN) everything seemed to be where it is supposed to be.  Am I misunderstanding how linking models works?

[pinaki.rajak]

If you already removed the linked model, and then reloaded it into the project using (ORIGIN-TO-ORIGIN) and if everything seemed to be where it is supposed to be then it is absolutely correct.

Now save that link model in this location and append in the navisworks, it will definitely superimpose where it is supposed to be.

Thanks Bro

You're a Genius!!

This sure did help me. I believe I had the same issue as the post author.

[kkaraman567G]

Great Job. Thanks.
Worked for me. My issue was that when i orbit around even a selected object, the model used to vanish. I had to do CTRL+Z or go to the pre-set home view.
"Go to "file options" <shift + F11> and change the near clipping planes from automatic to fixed with a distance of 1." this worked LIKE A CHARM. thanks again.

This worked for me !!! Thanks
