Elements Stretched in 3D Perspective View

[_GT_]

Hi,

I'm having a problem whereby inserts and components of various kinds are appearing elongated in 3D views. Below are a section view correctly showing a wall with a window and TV in/on it, and a problematic perspective view of the same elements in which both are stretched (the TV is stretched more).

Based on earlier posts about distorted 3D views, I've already tried the following:

- Confirm that model is close to Internal Origin.

- Update graphics card drivers.

- Disable hardware acceleration.

- Delete view and create new.

- Create new project.

I also understand that CAD elements in the project can cause such problems. Some manufacturer-produced furniture families that I've included in the project seem to have been derived from CAD geometry and they appear under the Imports tab of Object Styles. They were loaded as Revit families though and I'm wondering if it's even possible for CAD geometry to cause any problem once it's taken the form of a Revit family. There are no CAD imports other than the above and no linked files of any kind.

Cameras placed elsewhere in the model generate the same distortion, which I notice is always greatest at the edges of the view. Maybe some amount of this effect is actually intentional but the TV can't be 2' tall and 14' wide.

Any thoughts would be appreciated.

Thanks.

Let's recap here.  

Every perspective view that you create is distorted and irreparable - even in brand spanking new Projects?   Did I get the gist of it?

BTW: you can open a support ticket through your autdesk.manage.com portal if you want tech support.  FWIW.

I'm seeing the same problem in existing projects now that I create a similarly wide 3D view and look closely at it. I also did see the same problem when I replicated the current project starting with the same template. (Maybe the problem is in the template)

Yes I guess I could go that route. To be clear, I was only joking above. I very much appreciate your help and that of anyone else who offers it. I've found so many answers here in the past that I came here before even considering a support ticket.

- Open a plan view

- Right click the 3d camera view in Browser and choose Show Camera, you will see the camera highlighted in the plan view

- Now you can drag it cameral position, target position to adjust the angle

Often, instead of wasting time fixing the view it is just easier to delete the 3d cameral view and create a new one.  Your model is there, the materials and lighting are there.  Nothing is lost.

Hopefully that works.

I have been adjusting the camera in plan view, as you recommend. Unfortunately, no adjustment seems to give the desired result. 

I know that its generally advisable to delete the offending view in these cases so tried that as well. But any new view has the same problem.

I just posted a link to the model above. Maybe someone can find a problem there.

Thanks.

Here is how wide your camera is.  Just delete the view and drop a new camera in to create a new one.

Or change Field of view of the that view.

Yes, it's huge. But I've already deleted it and created a new one multiple times. every time I drag the crop region to capture the relevant portion of the building, the elements toward the edges of the crop region are stretched.

I realize that I may not be able to achieve what I want under these particular conditions. If that's the case, I'll just have to explore alternatives.

I am not clear what you want.  If what you want is to see the entire room without a distortion, then you will need to turn off the back wall and move the camera back far enough to capture the room.  Or create a panorama rendering instead of a still image.

I was hoping to show a wide view of a small room, with no distortion. I see the benefit of backing the camera away from the elements it's supposed to capture except that the "scene" is supposed to be of a small room. If I remove a wall, back the camera out and complete the portion of the model in between, it will have become a big room. Nevertheless, this is starting to seem like the best option at this point. Or the panorama, I'll look into that.

Thanks.

It is just optically impossible.  Creating a view in any 3D modeling programs is like composing a scene to photograph.  Wider view = more distortion and there is no way around it with just still images.  Human eye focal length is equivalent to 50mm and photos taken with that focal length have the most natural feel and more pleasant to viewers to look at.

Revit has no option for skewed images and I use the trick is

1. place camera far away from your building/room focusing your target item 

2.Hide everything till you find the your targeted elements

3.Crop the edges to right proportion

Interesting. This technique may have been what others were referring to above. It didn't occur to me to not only move the camera far away but then zoom back in on only the relevant elements. I'll keep it in mind, thanks.
