3D Drawing with AutoCAD - Section 8

35.4.2 Cameras

The Camera command creates a viewpoint in the 3D space to the model, indicating a focal length or field of view as if it were a real camera. The location of the camera and its point of view are represented in the 3D space as a glyph, which can be selected and manipulated with grips like any other object. The resulting view from the camera becomes part of the saved views that we studied in the 14 chapter on view management.
By default, you will not see the Camera section on the Render tab, the Animations section is not available (remember that we are using the 3D Modeling workspace), so you must activate with the context menu of the Ribbon Options.

To create a camera in our 3D space we use the button of the same name. We must indicate the location of the same and the crosshairs. For this last point it is always useful to use an object reference on the model. Once both points have been set, we can still configure other parameters in the command window, or in the dynamic input of parameters. When finished, press ENTER.

As you can see, with the final options of the command it is possible to relocate the camera and the crosshair, modify the focal distance or its height, among other options.
By definition, the different cameras that we are locating in our model acquire the names of camera1, camera2 and so on and with that name they become part of the saved views, as already mentioned. However, nothing prevents you from giving each camera a unique name.

If we click on a camera glyph, it and its point of view will have grips that allow to modify interactively with the mouse, its location and its focal length. It will also open the camera preview window, which will show you precisely what you will see through the camera when you activate it.

By default, camera glyphs do not print with the drawing, they are only visible in the graphics window, but can be disabled (or enabled) with the other button in your section. In turn, if we select a camera glyph and open the properties window, we will see the list of camera parameters that we can modify, including whether the glyph is printed with the drawing or not.
If we already have the View Manager, with which we can set and save any view of the model, what do we want the cameras for? Well, precisely to put them into action, like a real video camera. Which we will see once we have studied the following topic.
