Model Inspection QC Report
After clicking on ‘Model Inspection QC Report, ‘ the settings dialogue will open.
After configuring your settings, click ‘OK’, then choose the scan positions (triangles) to generate the report, and finally, click ‘Finish’ to complete the process.
After generating 3D QC reports, the processing time may vary based on your selected settings. Once the QC report is completed, open the Undet Browser.
In the Undet Browser, the recently generated QC report can be located at the bottom of the Group Selection tab.
Check out this brief video guide that walks you through the workings of this function and highlights the numerous possibilities it holds:
Surface analysis tools
Surface analysis tools will let you check and visualize model accuracy and scan station registration (compare the created model with point cloud data). The created analysis will stay in a Revit file. To review analysis on other PCs, you must have installed Undet for Revit plug-in, but plug-in can be without an activated license.* The Analyse tool is active only when loaded with the Undet project in the Undet Slice dialog.
Analyse dialog
Example with different GRID sizes:
Explanation of Inside – Outside depth interval selection
Set Inside – outside depth is needed to optimize calculation speed, depending on your expected deformation size. |
Multiple Face selection
Selection using the Multiple face command must be confirmed by pressing the “Finish” command. Selection works only for objects checked in the analyses settings (Surface Analysis Options) filter section.
1. Select multiple objects with rectangles by filter options.
2. Click “Finish” to start analysis calculations
Surface Analysis Calculation Methods
Mode (default) | – “Mode” selection often uses point cloud points in the selected GRID cell to calculate & visualize surface analysis. This is the default setting to calculate surface analysis. | |
Minimum | – “Minimum” selection uses first point cloud points in the selected GRID cell to calculate & visualize surface analysis. | |
Maximum | – The “Maximum” selection uses the last point cloud points in the selected GRID cell to calculate & visualize surface analysis. | |
Random | – “Random” selection uses random point cloud points in the selected GRID cell to calculate & visualize surface analysis. | |
Average | – “Average” selection uses average point cloud points in the selected GRID cell to calculate & visualize surface analysis. | |
StdDev | – The “StdDev” selection uses point cloud points by selecting them according to standard deviation in the selected GRID cell to calculate & visualize surface analysis. | |
Count | – “Count” selection analyzes & visualizes selected GRID cells whether they contain scan data. | |
Delta | – The “Delta” selection uses the difference between the Minimum and Maximum point cloud points in the selected GRID cell to calculate & visualize surface analysis. | |
Scan Diff | – The “Scan Diff” selection analyzes individual scan position points in the selected GRID cell to show the maximum difference between scan position data and see alignment errors of scan stations. | |
Scan Overlap | – The “Scan Overlap” selection analyzes & visualizes how much different scan positions data is in the selected GRID cell. |
Results example with different calculation methods:
Panoramic view from scan station |
Mode (default). Source: all points |
Count. Source: all points. A non-green spot means these elements are not modelled or have no scan data covering. |
Scan DIFF. Source: all points. Green spots mean that scan station registration (alignment) is done correctly. |
Data source selection
Decimated points | – Choose to analyze the model using decimated point cloud preview points (default density 5%, which can be adjusted in the Undet Slice dialogue). (Fast performance, suitable for quick analysis of the model) | |
Preview Points | – Choice to analyze model using all point cloud preview points GRID (Building type project type preview points grid 3x3cm) (Moderate performance, suitable for detail analysis of the model) | |
All Points | – Choice to analyze the model using all point cloud points. (Slow performance, suitable for very detailed analysis of the model parts) |
Results example with different data sources:
Decimated points (~5% of preview points density; decimation rate can be adjusted 1-100%) |
Preview points GRID (Buildings type project preview GRID 3cm x 3cm) |
All points |
Edit style dialog
In this dialogue, you can edit and customize surface analysis display styles. Colour ranges can be customized to meet target tolerances and needs.
Already prepared analysis display styles:
Count | – Choice to analyze the model covering different scanning stations | |
Gradient | – Gradient colouring range to analyze model accuracy (Blue – Red). | |
RCIS_BLUE_RED | – Choice to analyze model accuracy by RICS (Practice Standards) requirements; Color range: Individual Bar Charts (Blue – Red). | |
RCIS_CDE | – Choice to analyze model accuracy by RICS (Practice Standards) requirements; Color range: Individual Bar Charts (Red – Green – Red). | |
Undet (default) | – The default colouring range is used to analyze model accuracy by Undet client’s best practices. | |
USIBD | -Choice to analyze model accuracy by USIBD (U.S. Institute of building documentation) requirements; Color range: Individual Bar Charts (Red – Green – Red). | |
USIBD_BLUE_RED | – Choice to analyze model accuracy by USIBD (U.S. Institute of building documentation) requirements; Color range: Individual Bar Charts (Blue – Red). |
RCIS_CDE style colouring intervals | USIBD_BLUE_RED style colouring intervals |
Select/change analysis display styles
To change the surface analysis display style in the Revit properties menu, click Analysis Display Settings Edit…
In Analysis Results Settings, you can control the visibility of individual analyses and change the analysis display style (Count; Gradient; RCIS_BLUE_RED; RCIS_CDE; Undet (default); USIBD; USIBD_BLUE_RED)
