To produce an axonometric drawing you need to redraw or recreate a plan view at an angle of 45 degrees to the horizontal. The plan needs to be orientated so that the right view is achieved axonometrically, for example, there may be a particular elevation aspect of the building that needs to be represented. At this new orientation, the plan is redrawn and all lines are projected vertically. All measures remain ‘real’ and are taken from the elevation and section drawings.
Once the overall form or framework of the axonometric drawing is achieved, it is then possible to ‘cut away’ sections to reveal details of the building’s interior or its construction. Axonometric drawings allow a simultaneous view of the inside and outside of a building.
