| Rigging topos (rigging diagrams) would usually start their life as a projected elevation (see the Therion book for details). The walls can be drawn with regular wall lines. The surface can be drawn with whatever lines are appropriate (the example shows wall lines with "-subtype sand -outline none -clip off"), with linepoints to connect stakes and trees. | Rigging topos (rigging diagrams) would usually start their life as a projected elevation (see the [[https://therion.speleo.sk/downloads/thbook.pdf|Therion book]] and the [[extend|Extended Elevations]] article for details).

| The ropes are drawn with "rope" lines, using [[metapost#Simplified rope lines|Simplified rope lines]]. This is because the default Therion "rope" line tries to look pretty, but in doing so, it loses the control of what linepoints should just be corners rather than rebelays and what linepoints should have anchors. It has an all-or-nothing approach, which is not useful in a rigging topo, where each rope corner and anchor must represent an actual situation. In addition, the normal rope line often fails to draw all the rope parts (some go missing at the end of a line). The line can be turned into a rather thin line by enabling the "rebelays off" and "anchors off" option of at least one linepoint along the rope, but this is clumsy, and relies on you not editing it and accidentally removing it. The simplified rope lines code solves all these problems at once, by making a thick rope line that just behaves like any other basic line. | The ropes are drawn with "rope" lines, using [[metapost#Simplified rope lines|Simplified rope lines]].
