Re: Creating GM with both surficial lithologic map and borehole lithology
Hi Jackson,
The things I would look like trying here are:
- As you've probably seen in the 'Model From A Map' you can create the surface from the drilling then 'Add —> GIS Data' to the surface as an additional data, you've likely tried this, but I just wanted to confirm that's the route you've gone down.
- Utilising GIS lines rather than polylines, if you have a topo surface GIS lines can be drawn without worrying too much about elevation, then draped onto the topography surface. Polylines can travel above and below the topo easily and often you find if the polyline is slightly above the topo, it's technically outside the model boundary and won't be honoured.
- As an extension of the previous point you could look into turning off the 'Boundary Filter', the default will only let the surfaces see within the boundary box, this does let the GM run more efficiently by not looking for everything, but this might be limiting those polylines being 'seen'
- Also have a look into the snapping rules for the GM, if the snapping is honouring the drilling only this could explain why it's not matching your lines, you can change the snapping to 'All Data' or 'Custom' and tick the surface lines.
If none of these seem to do the job please shoot us an email at support@seequent.com, for us to have a more in depth look with you.

Re: Direction of seismic loads and the need for seepage analysis prior to stability analysis
Hello, the pseudo-static method applies an additional force based on the weight of the slice and the pseudo-static seismic coefficient (as shown below). The seismic coefficient is dimensionless and thus is always positive.
For more information on the pseudo-static method, please see the SLOPE/W course that is available in the Seequent Learning Centre or the Slope Stability Modelling Manual:
The need for a seepage analysis depends on how complex the pore water pressures are at your site. If the dam has many layers including filters, core, etc. a seepage analysis is likely necessary to capture the full pore water pressure conditions.
Re: who have the training Drilling data used for EDGE?
Hi @IanZhou I found this resource for Edge - is this useful? https://help.seequent.com/Geo/2024.1/en-GB/Content/estimation/estimation.htm
Re: Multidialog menu
Hi. Not through the use of Python API. I took a bit more complex path with GX language and C++.
Re: Groundwater analytical data over time best practice
hi @BenjaminLockwood great question!
You found a limitation when importing time series data within the Borehole Import. I'd suggest continuing your workaround of importing individual sampling events into the Borehole folder to eliminate the duplicate "Errors".
If using Leapfrog Works - You can get around these errors by turning on the Contaminants Extension and importing your table into the Points Folder as "Time Dependent Points". This will allow you to import these time series data without Leapfrog calling out an Error. You would then create query filters to isolate specific sampling events.
I've attached an example file of how you would set up your table for a Time Dependent Import.
*There are some limitations using this method- for example not being able to create Merged Tables like you can for interval data..
You can read up on adding Time Dependent Points to your Model here: Help Guide-Time Dependent Points

Re: Variable Orientation - Interpolation or NN?
I think you’ll find that if you flip the facing direction of the left hand mesh, you will get the result you are looking for.
The VO is calculated by decomposing the normal vector to the surface into 3 component vectors and interpolating those. The facing direction is important to determine the sense of the normal vector.
Kind regards
Mike
