✨ New Features
No new features were part of this version.
📈 Improvements
-
DRILH – DRIMB: Added option to place boosters at hole end, improving flexibility.
DRILH now offers options to place a booster at the bottom of the hole or, when a plug is used, at the bottom of the plug. DRIMB (in the Personalized Commands) has been enhanced to also support a booster at the hole end. When editing a booster, select “Booster at bottom” to add it, or clear the selection to remove it.
-
GMPSP: Added batch selection for structure polylines.
GMPSP now supports batch creation of multiple structure projections. Select all relevant GMP lines and set your preferences in the new dialog to streamline the process. The system will automatically insert the required structure polylines and blocks.
-
GSTV: The program now remembers your selected variogram during the session.
Previously, the command would only give you the option to preview specific search directions, and if you wanted to search another direction you would have to do a preview again. The system now retains the previously selected variogram search direction for a more consistent experience.
-
PLAPROG: Now displays your recorded progress for clearer tracking.
The PLAPROG command in the “Mine Planning” module now allows you to edit items individually. The progress view adapts to the selected object type: Drifts show total meters completed; Mining blocks show tonnage produced on a specified date; Tasks show the percentage completed.
-
DDHIDBA: Now you can import data from a CSV or TXT file right into your database.
Import assay or lithology data from a CSV or text file directly into your DDH database, without leaving the CAD environment. How to open it: Run the DDHIDB command (or equivalent menu entry). The dialog requires a configured .hdb.def file to be loaded. Workflow: Choose the import type — Assay or Lithology. Load your file — Select any CSV or delimited text file. The separator (comma, semicolon, tab, etc.) is detected automatically. You can override it if needed. A preview of the first 500 rows is shown so you can verify the content before proceeding.Map columns to database fields — For each column in your file, assign the corresponding field in the target database table. Required mappings (hole name, From, To, and at least one grade or lithology column) must be filled before the import can proceed. Validate — Before writing anything to the database, the tool checks every row for: Missing hole name, From, or To values
Missing grade or lithology data
Overlapping depth intervals for the same hole
Invalid rows and overlaps are listed with their row numbers so you can correct the source file if needed. You can choose to proceed anyway, skipping only the flagged rows. Import — The tool writes the data to the target table inside a transaction. Rows that already exist in the database (matched by hole name + From + To) are updated; new rows are inserted. A progress bar tracks the operation. A summary reports how many rows were inserted and how many were updated. Database support: Access (.mdb/.accdb), SQL Server, MySQL, Oracle, and ODBC sources — the same providers supported by the rest of the DDH module.
