Interactive 3D potential field modelling has become feasible in the last years and has been used on a number of projects in the oil industry and academic research. It does not replace conventional inversion methods but is advantageous in cases where we quickly want to test scenarios based on our geological and geophysical understanding of the area. Integration with other methods becomes much easier when the modelling is done interactively. Based on experience with the current implementation of interactive 3D modelling in IGMAS+, some practical improvements have been implemented and will be presented.
