Drawings and models created using various CAD packages are a core part of measuring and managing work on most sites. CAD linework can be uploaded into the Propeller Platform in order to visualize existing site conditions against important features and boundaries. 

Below is a list of best practices for formatting linework files to ensure they display correctly within the Propeller platform:

  • Linework should consist of vector data in DXF, KML, or KMZ format
  • Exclude all labels/annotations/grids unless absolutely necessary, as these tend to negatively affect the display of linework in Propeller
  • Linework should not extend beyond the survey data in the site
  • Linework files less than 2MB display better in Propeller
  • Separate linework into multiple files to keep individual file sizes below 20MB
  • 3D linework will reference the file's elevation attribute for displaying in Propeller
  • If the linework contains an "elevation" attribute—even if there are no elevation values—then the "clamp to ground" function can be used to drape the linework over the survey data in the site
  • If the linework displays far below the survey data, then add an "elevation" attribute to the file, re-upload the file, and use the "clamp to ground" function
