GeoTools is a general purpose CAD add-on software that aims to make the life of geographic data users (in AutoCAD and BricsCAD) easier. Within this software, we have pockets of specialized tool categories. One of them is an optionally priced module called the Geological & Mining Tools.
In the latest V 18.16 update, we have brought to you a fresh set of Geological and Mining Functions under the CAD environment.
Disclaimer: This is our very first attempt and just the beginning. Please be kind enough to report any errors and bugs you may find.

New Command Added Toolbar: Geological / Mining
The GEOL_ROSEDIAGRAM command can be used to create a rose diagram that plots the dip or strike azimuths on a steroenet. The input for this command are the dip/strike blocks created by the GEOL_PLACEDIPSTRIKESYMBOL command. This command is created to help erstwhile users of the GEOL_DH software and also supports the use of the GEOL_DH dip/strike block, which is named GDH1_DIP_STRIKE or GDH1_DIP_STRIKE_VER. For others, GeoTools has its own definition of the dip/strike block called GEOL_DIP_STRIKE which is available in the GeoTools install folder. Please do not change the orientation of lines in this block. There are two lines, a longer one representing the strike and a shorter one perpendicular to it representing the dip at the point. Their intersection is considered as the point of interest where the measurement was made. This block also has two attributes called DIP_AZIMUTH and DIP_ANGLE_FROM_HOR. You can add more attributes if you like but do not change the existing geometry or attributes. There are several options and parameters to control the data and presentation of the rose diagram as can be seen from the dialog box above. You can also represent the plot the Bowmann points, the computed. New Command Added Toolbar: Geological / Mining The GEOL_PLACEDIPSTRIKESYMBOL command is used to place a dip / strike symbol. This is a block which has a default name of GEOL_DIP_STRIKE and is stored in the GeoTools installation folder. It has a standard dip/strike symbol representing two perpendicular lines. Do not modify the geometric definition of this block as the program depends on its original definition and orientation to compute the dip and strike azimuths. The GEOL_PLACEDIPSTRIKESYMBOL command works in two mode: Single and Multiple. In Single mode, you pick a point on any existing crack or discontinuity line and it places the dip/strike symbol at that point with the orientation as per the slope at that point. In Multiple mode, this command can place dip/strike symbols across a selection of cracks with a condition that atleast one symbol is placed within a defined square window (which is also called the net size). You must select crack/discontinuity lines and also specify the layers where the cracks, net grid etc must be created and it will place a dip/strike symbol automatically at the location. Plese be aware that the dip and strike azimuths are implicitly stored in the direction/angle of insertion of the block. The direction of the longer line determines the strike direction, and the direction of the shorter perpendicular line determines the azimuth direction. The inclination of the dip (the angle it makes with the horizontal) is stored as an attribute DIP_ANGLE_FROM_HOR within the block. It needs to be manually entered by the user using either attribute edit commands or using either any of the tools provided in GeoTools.
An example of GEOL_PLACEDIPSTRIKESYMBOL run on cracks sampled on a 50m grid and a dip/strike symbol is automatically inserted in each grid and the grid is drawn as well. New Command Added Toolbar: Geological / Mining The GEOL_FLIPDIPDIRECTION command is used to change the dip azimuth direction. Select the dip/strike block(s) you want to flip and this command will rotate such blocks by 180.0 resulting in a flipped azimuth. New Command Added Toolbar: Geological / Mining The GEOL_CHANGEDIPANGLE command is used to change the dip inclination (the angle it makes with the horizontal surface). Select the dip/strike block(s) you want to change and this command will update the attribute DIP_ANG_FROM_HORIZ that stores the inclination angle (with horizontal surface). |
