Diagnose and repair the model

Use the Diagnose & repair commands to check and to repair errors and inconsistencies in the structure of model objects and the library database (xslib). By diagnosing and repairing the model you can ensure, for example, that empty assemblies are removed and that unused points and attributes are deleted. Repairing the model also corrects invalid object relations and hierarchies. We recommend you to diagnose and to repair your model regularly to maintain the consistency and integrity of your model databases.

  1. On the File menu, click Diagnose & repair.
  2. Select the appropriate diagnose command.

    The errors and inconsistencies found in the model are listed in a report. Some of them are automatically corrected, some of them are warnings that you need to correct manually.

    If a profile, material grade, bolt element or assembly, or reinforcement seems to be missing from the corresponding catalog, your Tekla Structures environment or a catalog file may not be the same as the model's original one.

    If there are solid errors in the model objects, these errors are listed in the report. The report is updated every time you run the Diagnose model command. (Solid errors are also listed in the session history log file TeklaStructures_<user>.log.)

    The following table lists the most common errors and inconsistencies found when diagnosing the model.

    Diagnosis result

    Description

    Action needed

    Empty assembly

    The assembly does not contain any objects.

    1. On the File menu, click Diagnose & repair.
    2. Under Model, click Repair model to delete the assembly.

    Missing assembly

    A part is not included in any assembly.

    1. On the File menu, click Diagnose & repair.
    2. Under Model, click Repair model to create an assembly and to move the part to it.

    Illegal profile

    An unknown profile has been found.

    1. Ensure that you are using the correct Tekla Structures environment.
    2. Use the model's original profdb.bin and profitab.inp files and save them in the model folder.
    3. Reopen the model.

    Illegal material

    An unknown material grade has been found.

    1. Ensure that you are using the correct Tekla Structures environment.
    2. Use the model's original matdb.bin file and save it in the model folder.
    3. Reopen the model.

    Illegal bolt

    An unknown bolt element or bolt assembly has been found.

    1. Ensure that you are using the correct Tekla Structures environment.
    2. Use the model's original screwdb.db and assdb.db files and save them in the model folder.
    3. Reopen the model.

    Illegal reinforcing bar size or grade

    Illegal reinforcement mesh

    Reinforcement with invalid properties has been found.

    1. Ensure that you are using the correct Tekla Structures environment.
    2. Use the model's original rebar_database.inp and mesh_database.inp files and save them in the model folder.
    3. Reopen the model.

    Invalid rebar geometry

    Reinforcement with undefined geometry has been found.

    See Check the validity of reinforcement geometry.

    Solid creation failed

    A model object with invalid geometry has been found.

    1. Ensure that you are using the correct Tekla Structures environment and profile catalog files.

    2. Try the following:

    • If there are cuts and/or fittings in the object, slightly adjust one of them or the object.

    • Check the pour geometry.

    • Remodel the object.

    If the model does not contain any errors or inconsistencies, a message is displayed on the status bar.
