Those are not LogPlot file extensions that I know of but 1998 was a while ago. You can send some examples to support or upload them here and I'd be happy to take a look at them and see if I can identify them.

You can open the DB in a number of different DBM programs and change the name of the field. If you're using the Sqlite (default) we recommend Sqlite Browser (https://sqlitebrowser.org/). Rockworks won't be able to address the field except in SQL queries.

There are 2 Lidar programs. one creates a grid under Grid|Grid Create and one that creates a Triangle Mesh under Utilities|3D. It sounds like you're doing the first. The question is how many cells there are in your grid. Its a common mistake to set grid dimensions that are too large. While your Lidar data has a very fine resolution, using that resolution will end up with a grid surface that is unwieldy. While there is no fixed limit to the size of a grid it would be good idea to limit the grid size to 300 x 300. You can adjust from there. Let us know what dimensions you're using.

Looks like a bug to me. I should have a fix by the end of the day.

Hi Julia, its using Inverse Distance based on all the data in the Filter method and in the Sector Based it also uses Inverse Distance but based on 1 sample per sector. Mitch

Its not obvious but you can right click on the Edit-Text table and select "Edit Rows and Groups". You can then select an item and drag it within the current group. Save it as a data template so you don't have to do this for every new file.

If you don't want the fill turn it off. In this case for less busy curves you could turn on the Resample option using Weighted Average or Cubic Spline. This may be fairly slow if you have a lot of points. Another option would be to Truncate the logs for a certain interval or increase the Vertical Exaggeration to spread the data vertically.

You can turn off the fill in the 2D Log Design tab. Select the active P-Data column and go to Fill Options. You can also change the Scaling options and turn off G-Value Filters and Resampling if they're on. Aming the column wider may help as well.

I'd look at your cutoff distance, half the cell size should work but if the cell size varies in the x, y and z spacing then it will be more hit or miss. Mitch

Somebody else may suggest a way to do this without modeling but if you use the Closest Point method with a small distance cutoff there will be no manipulation of the values. Just the original values and nulls.

If you model the arsenic you'll have several choices for extracting the level data. First you can create an I-Data Plan map for the elevation of your choice which creates a grid of the values. You can the use the Grid Statistics program on the grid. Secondly you can use your stratigraphic layers to filter the arsenic model and then run Solid Statistics on the filtered model. Mitch

A model is displayed in RockPlot3D and when a view is exported to shape file format its in a 3D foprmat best viewed in ArcScene or ArcGis Pro. These shape files can be imported into ArcMap but will only show a plan view. Since shape files are primarily data files you'll need to use categorize them within the Arc products to get a similar view. You might also consider exporting and importing as DXF.

He's probably using an older version. He needs to download the latest version.

Hi Laure, You're using the Trend Surface algorithm on Automatic and the program was unable to find a best Trend Surface order to use. You could either select the order in the menu or use another algorithm. Mitch
