C3D-PSBLOCK · Insert SS_BLOCK_22X17 into 22X17 C done

Imports SS_BLOCK_22X17.dwg as a block definition (not currently in the drawing) and inserts it into the 22X17 C paper space layout at origin, scale 1. Idempotent - skips if already inserted.

C# payload

// Import SS_BLOCK_22X17.dwg as a block definition and insert it into the '22X17 C' paper
// space layout at the origin, scale 1.
// The block is NOT yet defined in this drawing (only SS_BLOCK_11X17 variants are), so it is
// read from the external DWG via a side database and Db.Insert(...) first.
// NOTE: this ticket appends to the LAYOUT's BlockTableRecord directly, NOT the host's
// ModelSpace global - ModelSpace is the current space and we need paper space explicitly.
// Host owns Tx - no using/Commit on it here. The side Database IS ours to dispose.

Result

Imported 'SS_BLOCK_22X17' from SS_BLOCK_22X17.dwg.
Inserted 'SS_BLOCK_22X17' into layout '22X17 C' at (0,0) scale 1. Handle 222A6.
