Distortion in point grid projected onto an inclined wireframe

Hi everyone,
I’m trying to generate a regularly spaced point grid (e.g. 40x20 m) over an inclined wireframe in Leapfrog Geo.
I first created a regular XY grid and then stamped the Z values according to the surface. However, when doing this, the grid becomes distorted, since the real spacing between points changes due to the surface inclination.

Does anyone know a way to generate a regular grid directly on the surface, keeping the spacing constant along the wireframe plane?
Or perhaps a method to correct the distortion after projecting the points in Z?

I believe that having an option to rotate the dip of point grids would solve this kind of situation — and it could also be very helpful for other use cases, such as defining drill impact grids.

Any suggestions or workarounds are very welcome!

Thanks,
Lucas Silva

    Hi @LucasdaSilva

    I’m not sure if this is exactly what you’re looking for, and it may not be the most optimized workflow. I’m just sharing a workaround based on what I understand:

    1. Create a regular point grid

    • To create a grid of points, right-click on the Points folder and select “New Grid of Points” (see image below).
    • Set X = 40, Y = 20, Z = 25.
    • Click OK to create the grid.

    2 Export the point grid

    From the newly created Grid of Points folder, export the grid to your desktop.

    3. Create a reference plane

    • Press Ctrl + 3 to open the 3D view.
    • Draw a Flow Plane aligned with your wireframe surface.
    • Set the Dip and Azimuth according to your project.

    4. Create a mesh from the plane

    • In Meshes folder.Right-click and choose “From Moving Plane”.
    • Set the resolution to 50 and click OK.
    • A blue plane should appear in your scene.

    5. Import the grid points back into Leapfrog

    • In the GIS data / Maps and Photos folder, right-click and select Import 2D Points.
    • Select the file you exported earlier and click Open, then Finish.

    6.Create a topography from the plane

    In the Topography folder, right-click and select New Topography > From Surface, then choose the plane you just created from the Meshes folder.

    7. Project the point grid onto the inclined plane

    • Go back to the GIS data / Maps and Photos folder.
    • Right-click on “Grid_of_Points” and select Topography.
    • Choose the topography you just created.
    • You’ll now have a regular grid of points with the dimensions you set, projected onto an inclined plane.I hope this workaround is helpful for your situation.

    Thanks @PhamVietThai :) kind of you to share your idea on a workaround. @LucasdaSilva was that helpful?
