If you adjust the crop region of a perspective, the view dimensions will also be modified. To modify the 3D extents while keeping the same sheet dimensions, change the Focal Length. Use the following steps:
- Use the Camera tool to create a perspective view of your model.
- Click the "Full Navigation Wheel" on the right of your screen.
- With the navigation wheel open, right click the wheel.
- Left-Click where it says "Increase/Decrease Focal Length".
- Click and drag the mouse to increase or decrease the focal length of the camera view.
Using the above technique, you can increase/decrease the focal length in both internal and external perspective views without having to move the camera.
Use a sample project model in Revit and open the living room camera view from the project browser.
Tip: Press the F8 function key to toggle on the full navigation wheel and adjust the focal length of the interior view using the steps outlined above.
