Hello everyone, I am learning how to drawing geometry earth dam on flac 3d. I have a problem with bad blocks. I cant make zone because notification says "bad blocks". I started draw 2d geometry dam on extrusion pane then i use autozone tool and blocking tool. And then i extrude the geometry. I do the same thing when i draw geometry canyon. After dam and canyon have extruded, i go to building blocks and combine the dam and canyon so there are intersection between dam and canyon blocks.
Have I done the right steps? could anyone tell me the right step for drawing 3d geometry dam and canyon? Thank you
