* Increase or reduce the measured beam overall (BOA) of an existing boat hull design without returning to Setup.
* Enter a specific measured BOA and have the application solve the transformation needed to reach it.
* Scale the hull symmetrically to port and starboard around the fixed centreline Y=0.
* Preserve the hull’s longitudinal and vertical geometry—X and Z coordinates remain unchanged.
* Keep selected interior Y control positions fixed while the surrounding hull transforms.
* Temporarily disregard those retained positions when a completely proportional transformation is required.
* Detect and reject a requested BOA when retained control positions make the target impossible.
* Preview the resulting BOA and predicted displacement before applying the change.
* Keep calibrated reference images fixed while the hull becomes wider or narrower.
* Keep manual-weight X, Y and Z positions fixed during a beam transformation.
* Automatically regenerate stations, transoms, panels, hydrostatics, centres and fabrication outputs.
* Apply the complete transformation as a single Undo/Redo operation.
* Save, reopen and export the transformed design without losing the new dimensions.
* Explore wider and narrower versions safely using duplicated projects.
This allows different hull beams to be explored late in the design process while preserving the established length, depth, reference drawings and downstream construction geometry. #boat #design
