Seat MapSEATMAP-001

Groups the seats into zones - the pieces left when the aisles, vomitories and cuts are taken out of the tier - and gives every seat a readable address like "T1 05 S 25": prefix and tier number, zone number counted around the bowl in the axis direction, then the seat number running from the lowest tread up. In a bowl merged from several stands, tiers with the same tier label - by default the same tier number in each stand - count as one tier: one number, one run of zones around the bowl, one sheet. Wheelchair units belong to their zone too, numbered "W 1", "W 2". Outputs the SMD bundle for Seat View and Seat 3D, a zone map laid out one sheet per tier, and flat tables ready for a spreadsheet. Wire the BRD output of Stand 3D Plus; wire SHD from Sheet Setup to place the sheets

Colored ports carry the chain from one component to the next. The rest are values you set once. Outputs marked ⊞ can go into Table Out, which writes them to a spreadsheet.

Inputs

Build ResultBRDThe build result from Stand 3D Plus - the seats after every cut, with tiers and rows. Merge several into one branch and they are numbered as one bowl
OriginOriginBottom-left corner of the first sheet. Give each sheet component its own Default World origin.
Sheet DataSHDPaper size, columns, scale rounding, margins and text style from Sheet Setup
Zone PrefixPrefixThe letter in front of every zone label - T and tier 1 give T1 01 (default T)

Outputs
