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 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, KMZ, or LandXML format.
- Exclude all labels/annotations/grids unless necessary, as these tend to affect the display of linework negatively.
- Linework should only extend up to the survey data on the site.
- Linework files less than 2MB display better.
- Separate linework into multiple files to keep individual file sizes below 20MB.
- 3D linework will reference the file's elevation attribute to display.
- If the linework contains an elevation attribute—even if there are no elevation values—then the Clamp Layer to Ground function can be used to drape the linework over the survey data on the site.
- If the linework displays far below the survey data, add an elevation attribute to the file, re-upload the file, and use the Clamp Layer to Ground function.
