The type of perspective drawing where all lines from the plan are attached to the Station Point (SP) with projectors is called "Planometric Perspective".

Here are the steps to create a planometric perspective:

1. Start by drawing a plan view of the object or space. This is a view from directly above, showing the layout of the object or space.

2. Identify the Station Point (SP). This is the point from which the viewer is looking at the object or space.

3. Draw projectors from all corners and edges of the plan view to the SP. These are lines that represent the viewer's line of sight.

4. Where these projectors intersect with a vertical plane (which represents the picture plane or the viewer's field of vision), draw the corresponding corners and edges of the object or space.

5. Connect these points to create the planometric perspective view. This view shows the object or space as it would appear from the SP, with all lines drawn to scale and parallel lines remaining parallel.
