Module 7.3: Wall Flatness - With CAD Data with BuildIT Construction

BuildITConstruction-bty.png

WallFlatCAD-1.pngObjective:

Using BuildIT Construction to measure wall flatness using scan and CAD data.

You’ll learn:

  • A simple workflow for analyzing the scans verses a model.
  • Opening BuildIT, opening a BuildIT file and manipulating the viewport
  • Associating surfaces from the model to the point cloud.
  • Performing surface analysis of the scan data verses the CAD data.
  • Creating annotations of the analysis.
  • Creating a report from the annotations and analysis.

Activate the View of the Wall

Open the “Module 7.3.buildit” file by selecting “File> Open” and navigating to where the file is saved.

  • Activate the “Wall to Analyze” view.
    • Right click the view named “Wall to Analyze”.
    • Select “Restore View”. You may also use the “First person view” to navigate to the area of interest.

WallFlatCAD-3_2018.5.pngAssociate Scan Data to CAD Surfaces.

  • Now the scan data should be associated to CAD surfaces. This allows the software to only perform analysis with scan points that are near CAD surfaces, speeding up the process.
    • Select “Refine > Auto Associate”. AutoAssociateIcon.png
    • For “Clouds”, select the Cloud1 point cloud
    • For Geometries, select the wall with the three doorways, "surface p2590".
    • Ensure “Exclude points farther than” is checked with a value of 6 inches. This option will only search out up to 6 inches for points to associate. If the cloud is farther than 6 inches, it will be ignored.
       
    • Select “ApplyApplyIcon.png and view the result below:
      WallFlatCAD-4.png

 

Perform Surface Analysis

  • Now that the points have associated to our CAD, we can perform surface analysis.
    • Select “Evaluate > Surface Deviation Analysis”. SurfaceDeviationIcon.png
    • For “Surfaces”, select the wall with the three doorways, "surface p2590". This will pull all points associated to the surfaces.
    • Set the “Maximum Search Distance” to 6 inches, mirroring the distance set in the Associate command.
    • Select Preview  PreviewIcon.png to review the analysis.
      WallFlatCAD-5.png
    • For “Color scale”, set it to Rainbow – Red-Green-Red. This will make points that are out of tolerance yellow to red and points that are within tolerance green.
    • For “Analysis mode”, select “Colored cloud”.
    • For the “Limits”, change to “User-defined”. The tolerance used for this exercise will be 1 inch. Enter 1 for “Upper tolerance” and -1 for “Lower tolerance”.
      WallFlatCAD-6.png
    • Select “ApplyApplyIcon.png and view the result below:
      WallFlatCAD-7.png

Create Annotations

  • Now, annotations are needed to represent the deviation we see between the scans and CAD.
    • Select “Evaluate > Surface Inspection Annotation”. SurfaceInspectionAnalysisIcon.png
    • Select the Minimal annotation (3D only) radio button.
    • Select a scan point to annotate, then select Apply ApplyIcon.png to create the annotation, or middle mouse click.
      WallFlatCAD-8.png  WallFlatCAD-9.png
    • Repeat the previous step until several annotations have been created, use Set View SaveViewIcon.png to save a view with the annotations. Name it Deviation Analysis.
      WallFlatCAD-10.png

Create a Report from the Annotations and Analysis

  • Include the items created on a report.
    • Select items to include in the report.
      • Include the two views created, the analysis, and the annotations.
    • Right click and select “Add to Report”.
    • If the items are not in the intended order, they can be moved up or down by selecting and dragging the item.
      WallFlatCAD-11.png
    • Select Run GenerateReportIcon.png to create the report.

Recap:

Congratulations, you have completed the module on measuring wall flatness with CAD data! By now you should have a grasp of how to:

  • A simple workflow for analyzing the scans verses a model.
  • Opening BuildIT, opening a BuildIT file and manipulating the viewport
  • Associating surfaces from the model to the point cloud.
  • Performing surface analysis of the scan data verses the CAD data.
  • Creating annotations of the analysis.
  • Creating a report from the annotations and analysis.
