Camera Match is a 3rd Party Plugin to Vectorworks. This means that is doesn’t come as a standard. You have to buy it. I think you will find that this Plug-in saves so much time with visualization, that it pays for itself the first time you use it. I know when I bought it, it saved me a couple of hours on the first project. Available from http://www.panzercad.com
Camera Match has a tool that allows you to mask out areas in the rendered view. This will hide areas of the rendered model and make the photo come to the front.
When I first used the Camera Match, it worked well, but I did all my montage work in Photoshop. The Camera Match works much better now, and it is designed specifically to work in a viewport. So, we have to set up a viewport to get started.
Importing a photo into Vectorworks to use as a CameraMatch background.
Placing the Camera Match Object in the viewport.
Fine Tune the Camera View.
Placing a CameraMatch Reference object. The Reference Object is used to link the 3D model to the photo. When you place the Reference Object, it has to relate to a position it the photo.
