![]() ![]() There are different types of visualisation in architecture. In the next two sections, we will see how isometric drawings can be useful in both architecture and engineering. It is only useful in architecture but also in engineering. We can draw them to hide any unwanted elements for clean visuals. We can still draw isometric drawings after the design is finalised though.īecause isometric drawings are essentially 2D drawings, they may be easier to comprehend. Many architects have drawn isometric drawings to represent their ideas before a finalised design. It helps architects to visualise and represent design ideas. Isometric drawings are particularly useful in architecture. What Are The Benefits of Isometric Drawings? We can say an axonometric projection is isometric when all the lines and planes are parallel and have the isometric view angle. What is isometric projection? It is a graphical representation using the illusion of depth and undistorted presentation of the dimensions. Here is a term often used interchangeably with isometric drawing. The isometric view angle is also specific – 30 degrees from the horizontal axis. Unlike in perspective, the lines on each plane or axis do not intersect (or ‘vanish’) at a vanishing point. The view we get from an isometric project is called the isometric view. ![]() No one drawing can show the complete product we need a top view, plan view, side views and axonometric views. Then, what is the isometric view? In an architectural or product design, we use different views to show the overall design. ![]() Difference between Isometric View and Isometric Projection Isometric View Isometric drawings have a clear distinction from the other two wherein it has all dimensions to the same scale. There are three types of axonometric drawings - isometric, dimetric, and trimetric. It is also different from a two-point perspective in that an axonometric drawing shows three sides of an object while the two-point perspective only shows two sides of the project with lines heading towards the vanishing points. Isometric drawings are also axonometric, but what exactly does that mean? Axonometric drawings, or perspective or axonometry, is an orthographic projection to represent 3D objects with an oblique plane. Interestingly, this means there is no horizontal line in an isometric drawing. Any non-vertical lines are constructed at an angle of 30 degrees from the horizontal axis. F.D.K, 1995, A Visual Dictionary of Architecture). It is a paraline drawing with all the lines parallel to the principal axes drawn at real lengths and same scale (Ching. Derived from Greek meaning ‘equal measure’, isometric drawings are not distorted as the foreshortening of the axes is equal. What is An Isometric Drawing?Īn isometric drawing is a type of axonometric drawing, based on the isometric projection, that has the same scale on all three axes (X, Y and Z axes). Let’s find out more about these drawings and how you can use them in your projects. No manual trigonometry is needed (unless you are into that stuff).Despite the lack of such details, isometric drawings are still relevant and useful in architecture. The quite odd value 1.1498299142610595 can be found through a little modeling and measuring in SketchUp as shown in this quick video. ![]() Even if you don’t plan to measure the exported drawing it can be a good idea to have it to a defined scale to easier understand the size o the design. After doing this you can measure exact dimensions from the isometric drawing (as long as you measure along the axes and not diagonally). Then scale up the exported image by a factor of 1.1498299142610595 to compensate for the axes being viewed at an angle and not orthogonal to the camera. To get an isometric drawing to scale you can export that view to scale like any other view (either print to PDF or by using LayOut). The other way around just sets an arbitrary camera angle that gives wrong measurements, but is close enough to isometric for the cause of this issue to be very hard to find. To get an isometric view, first set the camera parallel projection and then set it to isometric. ![]()
