Mode

Sets the geometry to use for reshaping a selected object.

• rectangle: Lets you add or remove a rectangle shape.
• line: Lets you add a polygon to a shape or reshape a path. Only line can be used to reshape a path.

Snap Mode

Controls the shape of line segments; applies only when Mode is set to line.

Environment variable: snapMode

Snap

• Pins and boundary to grid: Snaps the stretched object to a grid depending on the block type. If it is an analog block, the place and route boundary and pin edges are snapped to the manufacturing grid. If it is a digital block, the place and route boundary is snapped to the placement grid and the pin centers are snapped to the routing grid. Pins with placement status unplaced, fixed, locked, or unknown are not snapped, even if they were touching the boundary before the reshape.
  Environment variable: snapToGrid
  During the stretch operation, in case the soft block is stretched outside the top-level PR boundary, then all the instance pins on the soft block, with the placement status as placed, are snapped to the manufacturing grid. This is irrespective of the block type because the routing grid is not initialized outside the PR boundary but the manufacturing grid exists outside the PR boundary.
• Pins to boundary: Snaps pins to the place and route boundary automatically.
• Snap Blocks Pins to: Snaps soft block pins automatically either to the Modified Edge or to the Closest Edge after the reshape is complete.
