It contains two point clouds of a construction site as well as the corresponding BIM model of the beams waiting to be built. The clouds have been scanned at intervals of one week. ## Compute progress Each sub-element of the BIM file will be individually compared to the point cloud; so it is recommended to remove the unnecessary elements such as screws or ground for example. This will also reduce the computation time. Select the cloud **Week1** and the BIM **Model structure** and go to [Progress Monitoring](/v1/docs/cyclone-3dr-bimprogressmonitoring). The first step of this workflow, [Analyze](/v1/docs/cyclone-3dr-bimprogressmonitoringanalyzec), will compute the percentage of completion for each sub-element. Here you can adjust three parameters: - The **first bar of the Coverage slider** (red to yellow) sets the coverage threshold for considering the sub-element as "**Incomplete"** and no longer as "**Not installed"**. Leave the default value 5%. - The **second bar of the Coverage slider** (yellow to green)sets the coverage threshold for considering the sub-element as "**Installed"**. Leave the default value 35%. - The **Exclusion Zone** is necessary to filter out points, by distance, which don't match any sub-element. This parameter is also suitable to take into account the point cloud accuracy. Here, you can set this parameter to **0.05 m**. - The **Resolution** is necessary to sample BIM objects. Here, you can set 25 cm. Click on **Compute**: the inspection is launched. The sub-elements are classified in four statuses: **Installed**, **Incomplete**, **Not installed** and **No data** (green, orange, red and grey respectively). ![0af15e9c-1126-42e0-be03-394b7392d9e9.png](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/0af15e9c-1126-42e0-be03-394b7392d9e9.png) Week 1 progress > [!NOTE] > Pie chart   > > You can hover your cursor over the portions of the pie chart to see the ratio of objects classified in each status. You can see that most of the beams are marked as installed. Click on **Next** to go to the [Check](/v1/docs/cyclone-3dr-bimprogressmonitoringcheckc) step of the workflow. ## Check the results Now, you can find on the left a tree containing all the sub-elements. By default, each node content is sorted by growing coverage. On the right, two views: the left one displays the overall **Progress View**, and the right view focuses on the selected sub-element. Click on a sub-element, whether in the tree or in the left view: the right view displays the element in inspection representation, as well as its matching points. If you think the thresholds were unfitting for your needs, you can come back to the [Analyze](/v1/docs/cyclone-3dr-bimprogressmonitoringanalyzec) step with the **Previous** button and **Reset** the analysis to compute a new one. If necessary, you can modify the automatic classification: select the sub-element you want to edit and press **SPACE**. Refer to the info text on the bottom left of the scene to know the key shortcuts. Finally, you can click on **Next** to go to the final step of the workflow: [Export](/v1/docs/cyclone-3dr-bimprogressmonitoringexportc). ## Export a report This step allows you to generate the report data and optionally to export a [BCF](/v1/docs/cyclone-3dr-bcfbimcollaborationformat) file containing issues to be imported in your BIM platform and software. Click **Update global view** to define the scene view that will be included in the report and in the [BCF](/v1/docs/cyclone-3dr-bcfbimcollaborationformat). You can add detailed views for each BIM object and you can choose not to export specific statuses to only keep track of what you're interested in. If you want to export a [BCF](/v1/docs/cyclone-3dr-bcfbimcollaborationformat), assign the issues to someone and choose between exporting only the **Summary** or **Summary + detailed issues**: - The first one will only export one issue with synthetic data of the analysis. - The second will create a BCF with an issue per analyzed sub-element. You can choose not to export specific statuses to only keep track of what you're interested in. You can now **Exit** the workflow. Note you can edit the analysis back later by clicking on the **Play** icon in the explorer tree next to the Progress Monitoring folder. Then go to the report editor to generate the PDF report. ## A week later It is time to check again the progress. Select the BIM object and the second cloud, called **Week2** and repeat the analysis with the same parameters. ![8edde8e9-4cbb-402e-9b24-b07437abaf97.png](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/8edde8e9-4cbb-402e-9b24-b07437abaf97.png) Week 2 progress
