Mining Routines

[Jeremy Cabrera]

Dear Autolisp expert,

I would like please to help me creating subroutines for a mining project. The purpose of these routines will allow creating a room and pillar underground mining design according to the following steps:

1.- Determine the limits of the project by clicking the upper left and lower right corners.

2.- Create a grid inside the limits. The grid must be created using the attached example.

3.- Once the grid is done create an option to rotate the entire grid using the upper left corner as pivot.

4.- Create an option to lower or raise the entire grid elevation.

4.- Create an option for loading a closed polyline.

5.- Trim the grid with the closed polyline and erase everything outside the polyline.

Thank you, I will appreciate your rapid response.

Regards,

Jeremy

You could "cheat" and use an array, then make it a block and xclip the area wanted .. EXAMPLE.
