{"params":{"piece":{"type":"choice","default":"straight","label":"Piece","describe":"Which pole of the route this is. Every value RECEIVES identically (arms through the pole on its z = 0 plane, pots at x = +/-0.42 and +/-0.98), so any piece follows any other. straight: the wires run on along +Z to the next pole at z = span. angle-45: the route turns 45 degrees here toward +X (angle-45-left: toward -X); the same pots send their wires out on the new heading, and the next pole is a straight copy turned 45 degrees about Y and set span metres along it. angle-90 (angle-90-left): the route turns a right angle toward +X (-X); the wires cannot leave along the arm they arrive on, so each level carries a second crossarm ACROSS the first, 0.30 m above it, with its own four pots; the next pole is a straight copy turned 90 degrees at x = +span (-span). Two crossarms and eight pots a level is why the right-angle pieces carry at most 2 arms (higher arms values build 2): turn a 3- or 4-arm route with two 45-degree poles. On an angle pole the ground stay moves to the outside of the turn.","affects":"geometry","options":["straight","angle-45","angle-90","angle-45-left","angle-90-left"]},"arms":{"type":"range","default":1,"label":"Crossarms","describe":"How many timber crossarms the pole carries, stacked DOWN from the fixed top arm at 7.30 m in 0.70 m steps (7.30, 6.60, 5.90, 5.20), each with its V brace and a row of four white pot insulators, each pot sending one wire to the next pole. 1 is a light single-arm route (4 wires, the default), 4 a busy trunk route (16). The pole, its height and every existing arm stay exactly where they are; the stay clamp follows the lowest arm. A pole may be followed by one with MORE arms (its extra arms start their own wires), never by one with fewer. The angle-90 piece carries at most 2.","affects":"geometry","min":1,"max":4,"step":1},"span":{"type":"range","default":12,"label":"Span","describe":"Distance to the next pole in metres, in 4 m steps: 8, 12 or 16 (other values snap), along +Z on a straight pole and along the new heading on an angle pole. Rebuilds only the wires: each still leaves its insulator and lands on the matching insulator of the next copy, sagging 2.5% of its length at midspan (0.20 m at 8, 0.40 m at 16). 8 is a tight lineside route, 16 an open country one.","affects":"geometry","min":8,"max":16,"step":4},"stay":{"type":"toggle","default":true,"label":"Ground stay","describe":"Whether the pole is stayed: a stay wire from an iron clamp 0.35 m under the lowest arm down to a stay rod coming out of the ground 2.60 m out, on the field side (+X) of a straight pole and on the outside of the turn of an angle pole, opposite the pull of its two spans. Real routes stay every angle pole and every few poles on the straight; turn it off for the plain poles between. Off leaves the pole and its arms untouched.","affects":"geometry"},"strung":{"type":"toggle","default":true,"label":"Span wires","describe":"Whether this pole sends its wires on to the next pole. On (default): every insulator carries a wire that runs span metres on to the next pole.

Here: 0 is clean timber with freshly red-oxide-painted ironwork; the arm clamps, brace plates, stay clamp and stay rod rust through one whole piece at a time (about a third by the 0.3 default, every one by 1); above 0.3 the pole, arms and struts bleach paler and the paint still left browns toward rust; from 0.2 a drying check opens low on the pole's hero face and lengthens with age.
