Geomodelr Software; Draw cross sections quickly using simple tools. Use Geomodelr's interpolation algorithm to refine them even quicker until you are happy with your geological model.
Draw geological maps too to interpret them and visualize them in 3 dimensions.
Cross sections are the input to Geomodelr's 3D algorithm, as they are the tools for the geologist to interpret. Geomodelr does not need horizon matching or surface construction to create a solid model. From the first cross section your model is solid.
