Auto Place by Text

This is the best method to place many panels fast. The panel is directed by text orientation with centerline going through text insertion point. The text itself becomes a panel name and it has to be in layer PANELNM to be found. User can specify retreat options, difficulty factors and entry width to be used for all panels before running command. To place the text in the panels easily use Draw Sequential Numbers, found under the Draw dropdown menu.

All panels created in one run become a single connected mine plan with no equipment assigned.

Required Input
Perimeter on PERIM Layer
Panel name on PANELNM Layer

The linework must be closed polylines. Each panel must have its own closed polyline (including longwall panels). The layer names do not have to be written in all caps. The text insert points must be inside the panel polylines.

Optional Input
*Advance Extraction Ratio on EXTRACTION Layer
*Retreat Extraction Ratio on RET_EXTRACT Layer
**Advance Difficulty Factor on DIFFICULTY Layer
**Retreat Difficulty Factor on RET_DIFF Layer

*The Extraction Ratio is not updated from the text on the EXTRACTION layer until running the Recalculate Extraction command on the Underground Pulldown Menu. There can only be one Extraction Ratio in a panel. Note that the Extraction Ratio will be automatically calculated if the pillars are drawn.

**There can be more than one Difficulty and Retreat Difficulty Factor per panel if the text is separated by Pin Points.

When you note the prompts below for entry width you will want to place the "longwall panels" and "room and pillar" works in two steps in order to get the correct advance distances reported. For this example the room and pillar works are on 20ft width, and the longwall width is 1,000 feet. Placing them in two steps will create two mine plans that can be connected using the Connect Mine Plans option.
