Practise basic weight followup from project creation to a checked weight report. Use this as a complete topic-based course or as extra exercises during Chapter 11 training.
Prerequisites: Access to a training database and permission to create and edit a project. Use your own training project. Use Save As before experimenting. Exercises are sequential: when starting at Exercise 2 or later, complete the preceding exercises or use a training copy supplied by your instructor.
Expected result: Five weight items, checked total weight and centre of gravity, a saved filter and a weight report. Do not add other items or group-level weight estimates to the exercise dataset.

Create a project with a unique Project ID, such as TRAINING_ followed by your initials. Select the training system and project type supplied by your instructor. Use metric units, check coordinate origin and positive directions, and display enough decimals for verification. All exercise weights are kilograms and coordinates are metres; check the units of the actual input fields.
Define a list-type custom code named Discipline with Structure, Machinery and Equipment as values. Add it to the Items window view. Note its actual Code ID for import mapping.
Check: Reopen the project, identify Database ID and Project ID, and confirm that the Discipline column is available.

Requires Exercise 1. Choose an appropriate existing editable WBS group for each item. Use unique ItemNo values within each group.
| ItemNo | Description | Discipline | Weight (kg) | LCG (X), m | TCG (Y), m | VCG (Z), m |
|---|---|---|---|---|---|---|
| 101 | Support frame | Structure | 1000 | 2 | 0 | 1 |
| 102 | Pump unit | Machinery | 500 | 4 | 1 | 2 |
| 103 | Control cabinet | Equipment | 500 | 6 | -1 | 3 |
Check: Three items; 2,000 kg; LCG (X) = 3.500 m; TCG (Y) = 0.000 m; VCG (Z) = 1.750 m. Ensure no other weights contribute to this total.

Requires Exercises 1-2. Download the Excel import file. Read its Instructions sheet. Fill both yellow WgtGrp cells with valid editable weight-group IDs from your training system. Import only the Import data sheet, with row 1 as headings.
| ItemNo | Description | Discipline | Weight (kg) | LCG (X), m | TCG (Y), m | VCG (Z), m |
|---|---|---|---|---|---|---|
| 104 | Pipe assembly | Machinery | 400 | 5 | 0.5 | 2.5 |
| 105 | Access platform | Structure | 600 | 5 | -0.5 | 2.5 |
Map each column to its field. Map Discipline to the custom code created in Exercise 1. Verify kilograms/metres and coordinate mapping: LCG (X), TCG (Y), VCG (Z). Run Test Import and review messages before importing once. Do not repeat the import into the same dataset.
Check: Five items; 3,000 kg; LCG (X) = 4.000 m; TCG (Y) = -0.033333 m; VCG (Z) = 2.000 m. Verify weight groups and Discipline values.

Watch: Importing Data.
Requires Exercises 1-3. Create and save an Items window filter showing only Discipline = Machinery, using your actual custom-code field. Sort the results by weight. Change the Pump unit from 500 kg to 600 kg to represent updated supplier information. Clear the filter and check the complete project.
Check: Machinery totals 900 kg before the change and 1,000 kg afterwards. The complete project totals 3,100 kg.

Watch: Sort, Filter and MultiEdit.
Requires Exercises 1-4. Check for missing weights and coordinates, incorrect coding and unintended duplicates. A zero coordinate may be valid; do not treat zero alone as an error. Clear or deliberately select all applicable filters. Produce a weight report covering the complete exercise dataset. Save a separate completed copy with Save As.
Check: Five items; 3,100 kg; LCG (X) = 4.000 m; TCG (Y) = 0.000 m; VCG (Z) = 2.000 m. Compare the report with the main-window totals.
