|| Surface analysis settings
& selection |
|Grid Size – select GRID cell to divide planes of the Revit model (components) to calculate surface analyze.|
|Depth Inside – set maximum inside depth from Revit model (components) planes, to analyze deviations.|
|Depth Outside – set maximum outside depth from Revit model (components) planes, to analyze deviations.|
|Calculation Method – choose a surface analysis method, in most cases, the “Mode” method is the best selection to start with.|
|Data Source – select data source (point cloud density), which will be used to analyze the model|
|Host – select model part types, which will be used to analyzed.|
|Orientation – select the orientation of model parts to analyze (Ex. floors – horizontal, walls vertical…)|
|Select all – Auto-selection of all host & orientation options|
|Single face – select and analyze single model face|
|Multiple face – select and analyze multiple model faces|
|Auto by Filter – auto-select and analyze model by filter option|
|Cancel – closes surface analysis dialog|
Example with different GRID size:
Explanation of Inside – Outside depth interval selection
|Set Inside – outside depth is needed to optimize calculation speed depending on the size of deformation you expect.|
Multiple Face selection
Selection using Multiple face command must be confirmed by pressing the “Finish” command. Selection working only for objects which are checked in analyses settings (Surface Analysis Options) filter section.
1. Select multiple objects with rectangle by filter options.
2. Click “Finish” to start analysis calculations
|Mode (default)||– “Mode” selection uses most often point cloud points in the selected GRID cell to calculate & visualize surface analyze. This is the default setting to calculate surface analyze.|
|Minimum||– “Minimum” selection uses first point cloud points in the selected GRID cell to calculate & visualize surface analyze.|
|Maximum||– “Maximum” selection uses last point cloud points in the selected GRID cell to calculate & visualize surface analyze.|
|Random||– “Random” selection uses random point cloud points in the selected GRID cell to calculate & visualize surface analyze.|
|Average||– “Average” selection uses average point cloud points in the selected GRID cell to calculate & visualize surface analyze.|
|StdDev||– “StdDev” selection uses point cloud points by selecting them according to standard deviation in the selected GRID cell to calculate & visualize surface analyze.|
|Count||– “Count” selection analyzes & visualizes selected GRID cell whether it contains scan data.|
|Delta||– “Delta” selection uses difference between Minimum and Maximum point cloud points in the selected GRID cell to calculate & visualize surface analyze.|
|Scan Diff||– “Scan Diff” selection analyzes individual scan position points in the selected GRID cell, to show the maximum difference between scan positions data, to see alignment errors of scan stations.|
|Scan Overlap||– “Scan Overlap” selection analyzes & visualizes how much different scan positions data is in the selected GRID cell.|
Results example with different calculation method:
|Panoramic view from scan station|
|Mode (default). Source: all points|
|Count. Source: all points. A non-green spots means that these elements are not modeled 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||– Choice to analyze model using decimated point cloud preview points (default density 5%, which can be adjusted in Undet Slice dialog. (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 model using all point cloud points. (Slow performance, suitable for very detailed analysis of the model parts)|
Results example with different data source:
|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)|
Edit style dialog
In this dialog, you can edit and customize surface analysis display styles. Color ranges, can be customized to meet target tolerances and need.
Already prepared analysis display styles:
|Count||– Choice to analyze model covering from different scanning stations|
|Gradient||– Gradient coloring 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)||– Default coloring range 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 coloring intervals||USIBD_BLUE_RED style coloring intervals|
Select / change analysis display styles
To change surface analysis display style in Revit properties menu, click Analysis Display Settings Edit…
In Analysis Results Settings you can control the visibility of individual analyzes and change the analysis display style (Count; Gradient; RCIS_BLUE_RED; RCIS_CDE; Undet (default); USIBD; USIBD_BLUE_RED)
Model Inspection QC Report
After clicking on ‘Model Inspection QC Report’ the settings dialog will open.
|Comparison Tolerance +-||Colours areas within the chosen tolerance in green from the 3D model.|
|Comparison buffer||Specifies the maximum distance to be coloured from the model.|
|Minimum Face Area (m²)|
|Sampling Step (pixels):|
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 initiating the generation of 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.
