Is there a limit to the number of vertices to calculate a volume. I realized every time i try to calculate volume with its vertices more than 20 i can’t calculate the volume as the compute button does not appear even after pressing the right mouse click button

Please do enlighten me

Thank you

Hi @sarawakenergypix4d,

We have been investigating this issue, and it seems that when the geometry becomes too complex, the software is not able to calculate it anymore. It seems that there is a mismatch between the DSM and the polygon when there are too many vertices. For now, we cannot propose any other workaround than calculating volume on a smaller area and then sum them.

We are sorry about that inconvenience
