Parameters

Defaults are the metric values the palette inserts. Every parameter can be driven by an expression or a target.

`Z12`	number (metres unless the description says otherwise)	0	Segment 12 rise (m)

Points

Point codes are what feature lines, styles and quantity take-off match on — they are the contract this subassembly publishes.

Point	Code	Placed	From	Expression
`P0`	MultiLink_Point	placed at the attachment point (an absolute offset/elevation)	—	`0 / 0`
`P1`	MultiLink_Point	offset + elevation delta from the reference point	P0	`Side*W1 / Z1`
`P2`	MultiLink_Point	offset + elevation delta from the reference point	P1	`Side*W2 / Z2`
`P3`	MultiLink_Point	offset + elevation delta from the reference point	P2	`Side*W3 / Z3`
`P4`	MultiLink_Point	offset + elevation delta from the reference point	P3	`Side*W4 / Z4`
`P5`	MultiLink_Point	offset + elevation delta from the reference point	P4	`Side*W5 / Z5`
`P6`	MultiLink_Point	offset + elevation delta from the reference point	P5	`Side*W6 / Z6`
`P7`	MultiLink_Point	offset + elevation delta from the reference point	P6	`Side*W7 / Z7`
`P8`	MultiLink_Point	offset + elevation delta from the reference point	P7	`Side*W8 / Z8`
`P9`	MultiLink_Point	offset + elevation delta from the reference point	P8	`Side*W9 / Z9`
`P10`	MultiLink_Point	offset + elevation delta from the reference point	P9	`Side*W10 / Z10`
`P11`	MultiLink_Point	offset + elevation delta from the reference point	P10	`Side*W11 / Z11`
`P12`	MultiLink_Point	offset + elevation delta from the reference point	P11	`Side*W12 / Z12`
