If I understand correctly what you are trying to do...

The align view just changes the current 3D viewpoint. To get a camera setting from this you need to tell it to place a camera for the current view. I forget exactly where this command is (the Image menu?) and I don't have AC running at the moment to check.

Perhaps I misunderstood. It now sounds to me that you are aligning a texture (picture) to an element in 3D. Please clarify what you are trying to do.

Oh. I guess someone else will have to take this one. I've never done that myself.

A quick search on Archiguide does wonders:

I think the Align View command is 10% useful, 90% frustrating. The chances of matching up the model with the photo's angle & distortion, is almost impossible.

It's often much quicker to just eyeball it by putting the photo in as a background in the 3D window, moving the camera around using the 3D navigation controls, and placing the camera into the path. Once it's close you can use Photoshop's Edit>Transform commands to do the final tweaking. The Skew, Distort and Perspective methods work a treat.

Here's an image I did for a client who gave me a very distorted photo!

Good points Link.

Another approach (the one I use) is to estimate the camera location and merge the rendering with the photo in Photoshop.

Sorry - I should have made myself clearer. Once I get the view aligned in the 3D window, I take the image out of the background and render it with a white background, then merge in Photoshop. Then I just transform the overlayed layer using the techniques described earlier.

This is much better than the cumbersome Align View command in ArchiCAD IMHO, but it does mean you need Photoshop!

I'm having the same problem, if I place the points where I want them, I don't get a camera...I sure would like to be able to use this tool and not have to jump between different programs

zoom into your image and carefully draw 2 'vertical' lines over the image, that you know the height of

snap to the top and bottom points when using the align view command, following the instructions it gives you

works best with oblique views, 'head-on' views are too sensitive to be useable
