[Qgis-user] Interpolation - IDW Interpolation

[Abel Chikoore]

Hi Chris,

Thanks for getting back to me. Maybe allow me to ask my question in this
way:

I want to create a 3D Geology Model in QGIS 3:44.

I have created my lithological units in .gpkg format.

How do i interporlate them using IDW Tool so i can view them in 3D?

Thats basically what im trying to do.

Regards,
Abel
