formz 8 view issue

Recommended Posts

When I attempt to zoom into the center of my model, the view content disappears. I have no luck in multi-view, and it's as if there is a radius from the model's center inside of which the model just disappears (or more accurately "whites out") in perspective view. Has anyone else experienced this? I have copied the model into a new file and have the exact same issue.

First thing to check - Have you checked whether "Clip Hither/Yon" is switched on in view parameters?

Second - Is your model far from the origin? More than likely it's this, ie. copying the model into a new file will still give problems if it's far from the origin.

Yes, the first thing I checked was that "clip hither/yon" was turned off. 

The model is centered on the origin.

The one thing that has changed is that I updated from fz7 to fz8, but an older version of the model works fine in fz8 in terms of the zooming in/views. I think the only real difference from the older models is my use of "scatter" and "grass" for some of the landscape. Aside from that, everything is pretty much the same. 

 

Thanks,

Hi SB,

 

Does Fitting the project as Rob suggests help?  Or if that causes it to zoom way out, then you could have an object far out in space.  If so, Frame Pick half the screen and Cut it from the file.   Then Fit again.  (If you see only the space junk then, select all and paste.)  

 

If you need further help with this, can you send a portion of the file that is not working for you so we can take a look?

I attempted fitting the project and then zooming in and had the same issue. Then I started to eliminate objects (en masse) and at some point in that process, the views unlocked so that I could see content as I continued to zoom in. I should note that eliminating the larger objects from the model (the landscape elements) didn't effect the issue. There is clearly something in the model that's confusing fz and making it buggy – but consistently so. I'll have to start eliminating progressively smaller groups of objects until I narrow things down enough to figure out where the issue is and then let you know. I have quite a few materials and it may be that one of them – or an odd geometry – is confusing fz.

 

Thanks

Hi SB,

 

If Fitting the project fits normally, then you should not need to delete any of those objects  -- only if you have an object that is way out in space.  However, if you Pick the desired object and Fit that, then this object (by default) will be fit -- and the center of interest placed on that object so that zooming and navigation relative to that object should be ideal.  Perhaps the additional details in this tech note will help?

 

Zooming with the Scroll whee works relative to the current view parameters, and how far it zooms is determined by the length of the line of site (which is the distance between the eye point and the center of interest for the active view -- whose values you can see in the View Parameters Palette). 


If you set the Center of Interest on or near the desired zoom location, then this can make zooming into that part easier. One way to do this is to use the Fit command -- and if you pick any objects and execute the (Command F) key shortcut, the picked objects will be fit -- and the center of interest will automatically be centered these objects. You can also try setting a smaller zoom in by percentage (closer to 100%) to reduce the zoom speed if you like. 

When simply zooming with the Scroll wheel alone, the eye point is moved closer and closer to the center of interest, and the percentage for this movement is controlled by the Zoom Options (palette): Zoom In By value. Thus, as you get closer and closer to the center of interest, you will notice that the zooming gets slower and slower. When this happens, zoom back out a bit until the zoom speed is moving you a reasonable amount.  Then, hold down the Alt and try scrolling back in again.  This will then move the entire camera forwards, and the rate of zooming (also controlled by the Zoom In value) will be constant (since the distance between the eye point and center of interest is not changing). 
 

If you need any further help, please send  a part of the file so we can take a look...
