Some clients are a bit confused about this issue. Vectorworks uses two concepts that look similar, images and textures. Some clients make use of these words as if they were interchangeable – they are not. If you take a photo on a digital camera, that is an image. If you import that photo into Vectorworks, it can be imported as an image (for use on 2D things), or it can imported as a texture (for 3D things).
In Vectorworks 2011, images are for planar objects (2D presentation), textures are for models (3D presentation). A texture in Vectorworks is a Resource, so we will be using the Resource Browser often to create, edit and apply your textures.
