A pipe with a fall is one that has a slight change in elevation along its length. Conventionally, a falling pipe is drawn on the isometric as if it were horizontal, with a symbol indicating the fall.

Before setting a fall, route the pipe as normal and dimension it. At any stage in this process, you can use Set Fall setfall_16 to define the magnitude of the change in elevation.

  1. Select the straight section of pipe to which to apply the fall.

  2. Click Set Fall setfall_16 on the Dimension toolbar. Alternatively, click Dimension > Set Fall.

    The Set Fall dialog box displays.

  3. Type a value for the fall. Although five options are available (Angle in Degrees, Ratio (1:n), Percentage, Gradians, and Incline (mm/m)) you only set a value for one of the options. The software automatically calculates the corresponding values for the remaining four options based on the value you enter. In the example below, a value of 1.0 is entered in the Angle in Degrees box.

    The software calculates the remaining four values and enters them automatically into their respective boxes.

  4. In the Fall to the section, specify which end of the pipe is higher. The available options are dependent on the route direction of the selected section of pipe. If the pipe runs N-S, the options are North and South. If the pipe runs E-W, the options are East and West. In the example above, the pipe will fall to the south making the north end higher.

  5. Click OK.

    The software updates the model to show a small triangular Fall symbol, indicating that a fall is applied to this straight section of pipe.

    SetFall

  • The fall that you specify is applied to all components of the straight section. It is only necessary to select one piece of pipe on the same straight for the fall to be applied to all the pipe and components.

  • The Existing dimensions options are available only if the pipe is already dimensioned. These two options allow you to specify whether the existing dimension is to be taken as the orthogonal or hypotenuse dimension:

    ExistingDimensions

  • If you select Make Orthogonal, then the dimensions of existing straights in the pipe will change (component lengths are fixed).
