cove.tool Plugin for Rhinoceros + Grasshopper for building performance analysis

3-Step Efficient Workflow to Upload Geometry to cove.tool using a pre-built grasshopper script. The script has been rebuilt from the ground up for easier use, viewing geometry errors, and security improvements! Integrates with your Rhino/Grasshopper workflow directly to upload any building geometry for automated building performance analysis. Save time and effort by inviting team members to your cove.tool project and stay up-to-date on design decisions being made.

Version 4.2.1 Updates!

  • "Click to Upload" option removes the need to lock the solver and makes the upload process more seamless.

  • Visualize Daylight meshes and analyze results in the Rhino environment, including floor-wise sDA and ASE breakdown.

  • Total triangle Count and Triangle count breakdown for Geometry categories to help with the geometry upload process.

  • Added a filter for corrupted or malformed geometry objects.

  • Upload Single- or Multi-use projects from the same script.

  • Significant performance improvements.

  • Enhanced error feedback/flagging for a seamless upload experience.

  • Simplified geometry referencing and upload from existing projects.

  • Secure Login to ensure user privacy.

  • Auto-find cove.tool projects through text search using the project URL or Project ID.

  • Added an area threshold to remove surfaces under 1 SF (improves performance).

  • Bug fixes and more!
