Hi everyone,

I’d like to share a small geodetic / construction-oriented workflow I built for Blender, focused on survey point data used in civil engineering, GIS, and construction projects.

The workflow consists of two lightweight Blender add-ons designed to work together:

:green_circle: Survey Points Importer

(CAD / GIS → Blender)

This add-on allows you to import survey point data (e.g. CSV / XYZ) into Blender for visualization, reference, and design context.

Typical use cases:

  • Bringing field survey points into Blender
  • Visualizing control points, layout points, or reference markers
  • Using real-world coordinates as a base for modeling or checks

Features:

  • Import survey points from external data files
  • Clean and simple point representation in Blender
  • Designed for geodetic / construction workflows (not artistic scatter tools)

:large_blue_circle: Survey Points Exporter

(Blender → CAD / GIS)

This add-on does the opposite: it lets you export survey points from Blender back into formats usable in CAD, GIS, or construction software.

Typical use cases:

  • Exporting layout or reference points created in Blender
  • Sending adjusted or processed points back to engineering tools
  • Bridging Blender with civil / survey pipelines

Features:

  • Export point coordinates from Blender
  • Output suitable for CAD/GIS and construction tools
  • Focused on engineering workflows rather than visualization only

:repeat: Example workflow

  1. Import survey points from field / CAD / GIS into Blender
  2. Visualize, adjust, or reference them during modeling
  3. Export selected points back for further use in engineering software

This approach allows Blender to act as a technical visualization and preprocessing tool, not just a renderer.

:information_source: Notes

  • These tools are not artistic scatter or FX add-ons
  • They are aimed at surveyors, civil engineers, BIM users, and technical Blender users
  • Lightweight, focused, and designed to fit into existing engineering pipelines

I’ll add screenshots below to show the UI and basic usage.
Video tutorial is planned later.

If you have questions, feedback, or ideas for improvements (formats, workflows, coordinate handling), feel free to ask — I’m happy to discuss.

Thanks!

Did you notice that you are importing the kind of data, that cannot really be stored precisely in 32bit floats that Blender uses for everything?

Thank you for pointing that out — yes, I’m fully aware that Blender uses 32-bit floats for all object and vertex coordinates, and that large values can quickly run into precision limitations.

That is exactly why Survey Points Importer handles large coordinates through a reference origin system. When the importer detects values above ~9999 (where precision can start being lost beyond the fourth decimal place), it shows a warning and suggests using the “Calculate origin at center of geometry” option.

This is documented in the product page and manual here:
https://superhivemarket.com/products/survey-points-importer--geodetic--construction-workflow

Using a reference origin keeps the effective coordinate values within a range where 32-bit precision doesn’t degrade critical data, while still preserving the relative layout of the points.
