 +The ladder is made from the standard Therion "fixed ladder"​ line. Although Therion has a "rope ladder"​ line as well, which seems to be the right symbol for a portable ladder that you rig for yourself, it does not have an actual definition so it does not work at the time of writing.

 Start with the extended elevation, with the "​extend start" and "​extend right" (or left) set as needed at the top of the first pitch. On reaching the first passage that needs to be shortened, allow one survey leg to continue into the passage. Then from the next leg, set all legs to "​extend vertical"​. This causes them to take up no horizontal space. Continue until one leg before the next pitch. Then set that leg onwards to "​extend right" (or left) again. Export this as an XVI, create a new th2 file for it, insert the XVI image, draw your extended elevation scraps around it. Potentially,​ you could even draw this as one scrap. Start with the extended elevation, with the "​extend start" and "​extend right" (or left) set as needed at the top of the first pitch.

 Use the [[metapost#​Break line|break line]] over the passage (with "​-subtype break -clip off -place top" options) to indicate that it is longer than shown (usually used for passages that keep their dimensions fairly constant). Alternatively,​ draw it as two unconnected scraps, with a break line at each of the ends facing towards each other (usually used for passages that have dramatically changed size). Use the [[metapost#​Break line|break line]] over the passage (with "​-subtype break -clip off -place top" options) to indicate that it is longer than shown (usually used for passages that keep their dimensions fairly constant).
