Re: 2d interpolation
Hi @obedduma,
Generally, I would say the standard RBF interpolant would do the job even though it is in 3D, you would just need to put a strong lateral trend to encourage the continuity in the direction you want. If your data is bottom of hole sample or surface samples that would also work as a 3D RBF interpolant.
When it comes to the outputs of the interpolant, if you want 2D then you can either use the in scene slicing tool or use the section tools which are described in the help here.
Re: Two Identical Slope/W Models Returning Different Factors of Safety
Hi Ryan, thanks for reaching out. The discrepancy comes from the fact that Model 1 gets its water conditions from SEEP/W and Model 2 gets its water conditions from a piezometric line. SLOPE/W tends to overestimate the pore-water pressure when the phreatic surface is defined with a piezometric line that is downward sloping (to represent downward flow), which is usually the case in an embankment. This is because it uses the vertical distance from the base of a slice to the phreatic surface to calculate the pore-water pressure.
When SLOPE/W uses the water conditions calculated with SEEP/W, the pore-water pressure values at the base of the slices are more accurate. In the case of a downward sloping phreatic surface, the pore-water pressure used in SLOPE/W will be lower due to the equipotential lines being angled. I've set up an example where you can see that even on the upstream slope of the dam, the equipotential lines are different. The first picture is with the drawn piezometric surface and the second picture is with the SEEP/W pore-water pressure conditions.

Re: Grid normalisation
No, I was trying to use the syntax for the min and max function that is described in the help. I just tried it and it worked.
The stats of the output grid norm are between 0 and 1
Not sure why it doesn't work on your OM installation. That is why I suggested that you report it is a bug.

If You’re Working with Leapfrog, This Webinar on Block Model Regularisation Might Help
I wanted to share a useful webinar that I think could really help if you’re working with Leapfrog models. Erik Scheel, a Senior Project Geologist, walks through the Block Model Regularisation feature in Leapfrog 2024.1.
This feature has a lot of potential for anyone looking to refine their block models, and I found the insights really practical. Here are a few things Erik covers:
✅ Averaging Grades & Variances: How to get a more accurate model by averaging grades and variances across sub-blocks.
✅ Better Control of Your Model: Tips on maintaining control of your block model and adjusting things as needed.
✅ External Dilution Impact: A breakdown of how to analyze the effects of external dilution on grades and mineability.
✅ Adjusting Parameters: How to tweak the parameters to match your specific goals and get the best outcomes.
A great resource if you’re working with these tools and want to improve your modeling process.

Exporting/Extracting Multiple Unclipped Meshes from a Geological Model
Does anyone else have this problem? I think this would be a great (and hopefully simple) change to Leapfrog Geo!
Extracting or exporting multiple unclipped surfaces from geological models. Currently to extract an unclipped surface you have to do it individually as the "Extract clipped mesh" tick box is only available there and not in any other menu or option for extracting meshes.
This would be a GAME CHANGER for me as I regularly have to extract over 100 surfaces - and to do this individually is painful and increases the risk of mistakes.
Re: Calculating material type volumes (m3) in a tunnel
The method to see the geology volumes within the tunnel is slightly different to that of seeing the numeric data within the tunnel. For numeric models, we can use the Evaluation to project onto the tunnel mesh. However, when it comes to category models like GMs, we need to use more of a cutting method to combine the geology model with the tunnel. The easiest way to do this is through the Combined Model.
Here are the steps:
Create a GM volume from the tunnel design
- Right-click on the Geological Models folder and create a new GM called 'Tunnel Extent'. Make sure your extents are around the tunnel. You can choose to have a base lithology column if you want, but I have selected None for mine because we are not using drilling data.
- Right-click on the Boundaries folder and select a New Extent > From Surface. Choose the tunnel.
- Drag your Output Volumes into the scene to ensure that the correct side has been used for cutting. If you have it the wrong way round this can easily be fixed by right clicking on the extent and selecting Swap Inside.
- Double-click to open the Lithologies in your model.
- Add a new lithology called Tunnel.
- Go to the Chronologies tab and change the Background Lithology to be Tunnel. Press OK.
Now you have a Tunnel volume
- Right-click on the Combined Models folder and create a New Combined Model. Tick the Geological Model and the Tunnel Extent models to combine. Press OK.
- Use the arrows to ensure that the Tunnel Extent is at the top, and use the model tick boxes to tick all of the volumes in the model (you don't have to tick them all if you don't want to combine them all). Press OK.
- Drag your Combined Model into the scene. You will see it is split into the different geological units.
- Right-click on the Combined Model and choose Properties.
This will have a list of the volumes within the tunnel and their volumes.
