Why does my ROI have cones in 3d view?

I drew my ROI in 2d view and it works fine. When I look in 3d view it has huge cones above and below the surface. There aren’t any points on the ROI at the vertices of the cones. It doesn’t seem to affect processing, just curious why. v2.60.

As I zoom it it gets smaller (stays proportional to the window size)

Hi @scavendish

Thank you for sharing the images. The “cones” you see in the 3D view is for vertical extension of the ROI. (Region of interest (ROI) in PIX4Dmatic)

The development team is aware of this, and they need to improve the logic that scales the size of those cones based on the ROI horizontal extent.
