Open extension “Clash Detection”
Select Point Cloud “Point Cloud”
Create new Clash Detection Project
Define 3D Path
Select the polyline from the “path.ovf” vector dataset. Make sure you can select objects from this dataset. Depending your Selection Preferences, the Vector Dataset must be set as Active Dataset to be able to select objects from this dataset.
Select Shape
Select the shape 4000×4000
Position Shape on Path
Ground height offset of 0.7m, centered horizontal alignment (2m each side).
Set Analyse Parameters
Check Hits, Near hits and Ignore Ground Level.
Set Min Points for cluster to 5 and Near Hits to 1m.
Run Clash Detection
Once a 3D Path and a Shape a specified, the Clash Detection process can be executed. Clusters of detected clashes will be added to the result list one by one, beginning of the segment. The process will identify 21 clashes, including 11 Hits and 10 Near Hits.
Visualize Results
Check “Show labels” and “Highlight selection”.
Double click result [1] to focus and review the result. Set “Follow Up” or “Ok” if no follow up is required. Do the same for all detected clashes.
