You can also automatically generate isometric views using the drawing command VIEWBASE. In BricsCAD, the LookFrom widget automatically aligns any drawing to an isometric view, so long as the perspective value is set to ‘off’. They will need to be re-drawn from scratch. With other drawing techniques such as perspective, oblique, plan or diametric views it is not possible to reused already drawn items. There is also no change in the sense of scale when an object is moved forward or backward. The advantage of drawing in this manner is that an object can be freely rotated, re-positioned and reoriented without redrawing it. In other words: the lines of a face are all drawn at the same angle. It’s a form of axonometric perspective (there is no foreshortening). This is because the angle between the x, y, and z axes are all 120°. Isometric drawing comes from the greek ίσο μέτρο “íso métro” meaning equal measure. Isometric drawing is something we technical illustrators use every day, but how often have you stopped to think about where it came from or why we use it? What is isometric drawing? Examples of different drawing styles Isometric drawing is a particular style of drawing where the angle between the x, y, and z axes are all 120° and there is no perspective.
