The command for deleting all cells with less than five points is:
del cel lt 5 nr ; # delete cells with less than 5 numbers. 52 number of cells were deleted.
However, two fault traces was also deleted as the picture to the right shows.
The new trimmed fault traces were added back into the project. Then the two fault traces that also were deleted are selected from the original dataset by the command object Edit points and lines-Select-Select Cell . For each selection the command object Append polydata from workspace was used as shown below. The edited fault traces are saved in the project as Faults_edited data.
Menu for appending selected data to the fault set
Close the fault line traces
Looking at the fault dataset after removing the fault throw boxes one sees that the traces are not properly closed. Make the fault dataset active and do the command in the shell:
mak cpl ; # make closed polygon .
All but two fault traces were properly closed. For these two exceptions they were closed with Faults_edited->Edit points and lines-Digitize-Start. Use keyboard n for connecting to the nearest point and close the remaining gaps. Use keyboard f between the cells. Finally the fault trace picture looks correct as shown in the picture to the right.
The fault traces are now ready to be used in fault gridding. To check that they are correctly edited one usually perform the bmo test; i.e. grid the fault traces within the grid window with the bmo command. That test is also part of the gridding panel in the fault menu page. Grid cells should only be present inside the fault traces for a proper gridding of seismic lines and fault traces. |
