Hello,

Which version of Leapfrog are you using? I am using version 2025.3.0 and the legend title text seems to match the numbers.

Are you displaying a numeric model in the scene? Not a cross section layout legend or anything?

Our next Leapfrog Geo Mastery Session is going live on the 25th of March.

Join @NiklasSääv, as he deep dives advanced control with structural trends in Leapfrog Geo.

During the session, he'll guide you through:

• Moving beyond isotropic models for more realistic representations.
• Mastering key trend types for various geological scenarios.
• Precisely controlling trend strength and shape.
• Utilizing the latest features in Leapfrog 2025.3.
• Applying trends to a variety of geometries.

The Mastery series is perfect for Leapfrog Geo users who have established foundational skills but are looking to elevate their expertise and become more confident and efficient.

Easiest would be if the original material would come in as HW and FW meshes then you can create a deposit layering to create the effect you want. That does come with it's own challenges since they would need to cross the entire boundary in order to work.

I came up with a way that is somewhat dynamic.. There is probably some room for improvement here.. Essentially it comes down to create the A splits in Leapfrog using static offsets and Mesh Operations.

Example, note the pink and purple colour not going all the way out since I wanted to test this assuming that the B units didn't go all the way out all the time.. And I only tested this in simple shapes..

Mesh Preperation

1. Import /reload the Meshes
   1. Import /reload the B meshes again
   2. Set an offset on them (my example uses 1m in X)
2. Clip the A mesh using the B meshes so you get it split up into individual parts (still in the same objects). This step would need to be repeated a few times unless you do a Boolean Mesh first. Img below.
   
3. Clip the offset B meshes using the Clipped A mesh. (it's the wireframe mesh in the img.) Ideally I want this in the middle of the B unit.
   

Geological Model

1. Create a stack of Deposits from OFFSET surface to generate the background A units. I used 1.1m offset to get it in the right location. You might have to play with this one.
2. Add the B units as Intrusions as before.

Not super simple, but can be done..

Hey Francois, currently the answer is no, the stereonet tools are somewhat basic in Leapfrog currently, but this is an excellent suggestion and I second that it would be of value!

Thank you for your reply. That would be really helpful because we would be able to see the fault or shear's movement with just a quick look.

This means that a new column is needed in the data to indicate the direction of movement.

Cheers,

Hey community! Question about dynamic geological model using closed meshes as dividers

I'm trying to build a geological model in Leapfrog Geo 2025.3 with the following setup:

• 1 envelope mesh (HOST ROCK) — the main host rock
• 4 tabular body meshes (B0, B1, B2, B3) — geological dykes that crosscut the HOST ROCK
• My goal: HOST ROCK should be divided into 5 separate lithologies (A0 to A4) by the 4 B bodies, and the model should update dynamically when the B meshes are revised by the geology team

So far, I've successfully modeled the B bodies as Intrusions from mesh inside a Geological Model and they correctly cut the HOST ROCK. However, I cannot get the HOST ROCK to split into the 5 zones (A0 through A4) as separate named lithologies in a dynamic way.

My limitation: I only have closed mesh solids — no point data, no surfaces and no drillhole data.

I'm attaching one image showing the current state — you can see the B bodies (dykes) cutting the HOST ROCK (As), but all as separate meshes with no drillhole data

Any ideas are welcome. Thanks in advance! 🙌
