Ive used pix 4d in the past a couple of times with no issues. But now for some reason i cant compute volumes. I draw round the piles using left click, finish with right but the compute button doesnt work

Any advise please?

Kind Regards

Would you please let us know if DSM is generated? The volume is calculated using the DSM data. I also suggest updating the GPU drivers by following the steps described in [How to update the NVIDIA graphic card](https://support.pix4d.com/hc/en-us/articles/208614566-How-to-update-the-NVIDIA-graphic-card). Let us know if the same problems occur with the other volume calculations.

Warm regards,
