It is really simple! You just have to enter the borehole data including soil layers, co-ordinates and groundwater level. Then you just have to create the sil profiles by selecting the boreholes along the profile. VisLog automaticlly will connect the similar soil layers between boreholes, giving you a 3D model.
If you are using gINT software for borehole log drafting, VisLog can directly import your borehole data from gINT files.
You can find all the information and download the VisLog here.
