Avoidance zones
When placing a separate VCL file with the file name "<file name>.avoid.VCL" in the project’s root folder, closed circles and polygons present within the VCL file are used as the project’s avoidance zones. This behavior matches the current behavior of DXF/DWG avoidance zone files. The Siteworks software does not support embedded avoidance zone boundary types as defined in Trimble Business Center; it simply treats any closed polygon present in the "<file name>.avoid.vcl" file as an avoidance zone.
