In Isos, the perception of depth is included although it is a three dimensional representation but pipes are indicated as solid lines for simplicity and the bends are also represented as a combination of lines. It does not give any information about the dept of the equipments or valves.
The pneumatic and electrical signals are shown as dashed and dotted lines. The transfer of materials from one equipment to another equipment is shown as a solid line. The interconnection between them is shown as a line. In PID, the equipments and the process control instruments are represented as two dimensional symbols.
They are also commonly referred to as isos in process and chemical industries and in academics also. But bisecting angle D on paper, even though it represents the same angle on the cube as C, would result in a different split of on-the-cube angles represented, because it would not hit the midpoint of the lower-left edge, the way the bisector of C would hit the midpoint of the right edge.A piping isometric drawing is also a detailed diagram which is used to represent pipes, pipe fittings, bends, valves, welds etc. For instance, a simple angle bisector on paper of an angle that doesn't represent 90 on the cube would not represent accurately the bisector of that angle on the cube. And note especially that you can't just determine which of those adjustments to make based on the particular directions on paper, because A and C are exactly the same angle and even aiming in the same direction on paper, yet A represents 90 on the cube but C represents 45.Īnd when you get into angles like some in your image, that aren't "clean" like these in relation to the isometric directions, the complications increase dramatically. C is 60 on paper but 45 on the cube, but D is 30 on paper but also 45 on the cube. Just for some of the complications, consider this cube in isometric:Īngle A is 60 degrees on paper but 90 degrees on the cube, but B is 120 on paper but also 90 on the cube. I doubt very much that there's a reliably accurate way to do that.
