Point Cloud Options

When testing for interactive clashes between the model and point cloud data that has a spatial occupancy map created, you are able to select between two alternative testing methods from the drop-down list:

• The Cell method highlights the boxes in the map where clashing takes place, allowing you to quickly identify areas of concern within a model. The Cell method is quick because it requests less information from the Laser Modelling System (LMS) where the scanned referenced data is sourced.

• The Exact method provides more detailed results, showing exactly where the AVEVA E3D Design geometry clashes with the laser model. The Exact method requires detailed point cloud data from the third party LMS, it can be slower to identify clashes, particularly in larger methods.

Both methods are driven from AVEVA E3D Design but also explicitly invoke clash detection functionality within the LMS.

When using point cloud datasets in the cloud, the option to use Batch cloud clashing mode becomes available. In this mode, instead of clashing elements one at a time against the point cloud data, multiple elements are sent to the point cloud manager and then all clashed in one operation. This greatly reduces the time required for clashing in the cloud. By default, batch clashing is enabled for cloud datasets. Although the functionality can be turned off by the user, this is not recommended. Once a clash has been performed using batch clash mode, all subsequent clashes in the session will be performed in batch mode.
