LINEAR Revit V26

Missing or Outdated Parameters or Parameter Values

Problem

In an existing project, you discover missing or outdated parameters or parameter values, for example using the properties of a component after a pipe network calculation or due to missing or outdated values in placed labels.

Cause: Outdated Parameters on Components

The parameter names and/or parameter definitions of the components in your existing project do not match the parameters currently used in the LINEAR software.

Solution

    1. Calculate the pipe network and then navigate to Analyse Tab ➤ Labeling ....
    2. In the Labeling dialog, click on Write Parameters to Network Components.

    This command writes the determined parameter values to the components of the pipe network and updates all parameter names and definitions. Family parameters that are defined differently are replaced. Family parameters with new names and project parameters are added. Obsolete parameters remain on the component, but are no longer taken into account and can be removed manually if necessary.

Cause: Obsolete Parameters in the Labeling Family

You are using obsolete parameter names or definitions in your user-defined labels.

Solution

    1. Navigate to Revit Ribbon ➤ LINEAR ➤ Manage ➤ Dropdown List: Show Parameter File to ensure that you are using the latest parameter file.
    2. Open the faulty custom labeling family and check whether modified or renamed parameters are being used. Use the following tables to do this:
