Copy/Paste Marquee Area from Project Window

You can use the Marquee tool to copy and paste an area of the 3D Window, a Section/Elevation/IE or 3D Document window, or a Model Picture Window.
3.
Choose Edit > Copy.
If you are copying from the 3D window using the OpenGL 3D Engine, all images will be pasted in pixel format.
If you are copying from the 3D window using the Vectorial 3D Engine, a dialog box appears during the Copy operation giving you options for how the image will be displayed on the screen.
Note: If you are copy-pasting construction elements, they will be placed as 2D elements (points, lines and fills.)
Note: You can paste into other 2D model windows, but the pasted elements will behave as 2D drawing elements only, not model elements.
