Yes, it could be a known issue. I was referring to the fact I (personally) had never heard anyone mention it in the modeling area where I have (mostly) worked since joining the Maya team. -- Brent

I posted this to the Area yesterday and the only response I got back seems to confirm that. I'm finding that there are times when Frame Selection actually does affect the lens position, but for some reason it seems like it is broken in most cases for the ortho panels. What Default View is doing is correctly positioning the lens outside the extent of the geometry by positioning the Z. When you hit Frame Selection again, you're then setting the ortho width and that frames the XY. It does not appear to have any issues setting camera position for non-ortho cameras. So this must be an error in how it resolves the framing in ortho mode only. You will find that the predefined Front Bookmark also works correctly setting the Z position like you would expect, and when the camera doesn’t reposition properly after a Frame Selection, if you just alt-middle click drag the camera a little to one side or the other, then frame selection again, it will actually change the Z position a little. After several repeats it will find its way outside the geometry extent. I would be surprised if there was a divide by zero error hidden in the Frame Selection code somewhere.

Your suggestion works - upon inspection the default cameras are too close to the large objects, which effectively clips the closest parts. I had no idea, as there is still a ton of stuff I don't know about Maya. This is after framing the objects using both A and F in order to see what might fix it, plus trying to dolly away to no avail. What I do know about Maya - never expect it to act or behave sensibly nor logically :-/ Since you know the ins and outs - it drives me crazy that there apparently is no actual zoom function in Maya wievports, like the one we know from Softimage. I am talking about changing camera fov using Z interactively while working on framing in a scene. Asking our Maya residents they reply they don't use that so they don't know how. They say to select camera and change fov in the Attribute Editor. How do you manage stuff like that (assuming you have found a smarter way). Thanks Morten Den 4. oktober 2017 klokken 19:15 skrev "Ponthieux, Joseph G. (LARC-E1A)[LITES II]" <j.ponthi...@nasa.gov><mailto:j.ponthi...@nasa.gov>: So it seems I was wrong. The 1000.1 value can change when using the Framing function. The F key. But It doesn’t change when attempting to zoom or dolly in the front, top or side viewport using the mouse. What I am seeing is the part of a really large object closest the camera is clipped and the near clip is incapable of seeing anything because the camera head is not actually in front of the object. And I can't set near clip to a negative value. Is this what you are experiencing? To replicate, in a new scene create a sphere with a radius of 1500 units. Select the sphere and hit F key in the Front viewport. This illustrates that part of the 1500 radius sphere is past the normal position of the Front camera which is 1000.1 units Z. You can clearly see the problem if you have the viewport set to shading. So in Front camera for example you have to manually set camera Z to a value which places the camera in front of all geometry, such as 1600 units Z, which means you have to know the geometry extent relative that camera. And then make sure the far clipping plane is beyond the far side. It seems that you can somewhat correct the situation by executing View>Default View for the viewport in question, executing the A key or selecting the object or objects then hit the F key. Then suddenly it will set the Z extent in front of the selected geometry without difficulty. I'm seeing this in 2018 and all the way back to 2014. As long as your scene is never beyond 2000 units wide, or twice the distance wide of the camera position to world center, you're not likely to ever see the problem. Further, the inability to frame on the object appears to be affected by the size of the object rather than its position. In other words multiple objects at a distance of 3000 units apart but at normalized sizes seem less likely to exhibit the framing problem than one object that is 3000 units across. I don’t recall if this is how it worked in the past. This does not seem normal. But this seems to not be framing the objects correctly nor permitting the user to dolly the orthographic cameras in a predictable fashion without first executing Default View which apparently knows how to correctly set the orthographic camera's lens position outside the volume of the existing geometry.

Having issues at 1500 units does not seem normal. I suspect the camera has been edited. Check the following in the Front Camera: 1. Select the front camera in the outliner 2. In the attribute editor for front, is Z set to 1000.1. Top should have always have 1000.1 for Y, and Side should have 1000.1 for X. These should never change though the remaining position values will. If they are not 1000.1, does setting them manually to that value fix the problem? Alternatively, does executing View> Default View for each viewport fix the issue?

I have worked with scenes 100x larger in Soft. It seems ridiculous. Changing clipping plane values has no effect on the default scene cameras - I am on Maya 2016 base version if that makes any difference, and the cameras are neither scaled nor rotated as far as I can tell. I use wip cameras that I create for moving cameras around as I don't know the do's and dont's with Maya default cameras, so I thought it better to leave them be.

Sometimes things get weird with astronomically large scenes. You should be able to edit the Far Clip Plane for frontShape, topShape, or sideShape. I just tested this and it works as expected. But the numbers I am using are less than 100K. Have the Top, Front, or Side cameras been edited in any unusual way? They are special cameras, special objects if you will, that can act bizarrely if treated like real objects, or articulated in ways they are meant to be. Rotation or Scaling for example. They can be moved but should only be articulated using the viewports. They are generally hidden by default and should remain that way. I do remember having issues when treating them in a non-typical way. But there is no obvious reason I can think of that would directly prevent their clipping planes from being edited.

Huge scenes that were clipped off in the default cameras, so a hard time selecting stuff in the viewport. Due to time limits I never had the chance to dive into this, so anyone who can answer the question please do. And scaling up stuff, including cameras can result in some nasty render surprises. Unless that has been fixed in the last couple of versions.

It appears if I work with very large objects, like in landscape scale, the objects are clipped by distance in the respective cameras. Changing the clipping planes of these cameras does not work - the objects are still clipped. A very unfortunate side effect is I can't select components of my objects that are outside the clipping planes, ie. if I have a long grid road piece and want to select edge vertices to move them all, I can't do that from the side or front view - only the vertices visible inside clipping planes get selected. The workaround (usual Maya style) is to either make new camera and position as side- or frontview camera, because for new cameras clipping planes work(!), or to select edgerings and move them instead of selecting all vertices in sideview - or as our local Maya resident (a patient man these days ;) says, to work at smaller scale and then scale up at the end. I say it is moronic. I am sure you smart people have run into something similar and perhaps have a more nifty workaround I can use.
