How does CuraEngine determine Scale|Move|Mirror settings from Cura desktop app ?

CuraEngine produces different gcode files for different settings set for "Scale" in Cura desktop application.

However I compared the settings which were passed to it(as they are visible in the terminal) and found no difference in those settings passed whether it was a normally placed model or scaled model or with differently positioned model, but the gcode files for such different settings was different. How to determine in which way the engine is taking those settings ?

OS: Ubuntu 14.04

Cura: 2.3

CuraEngine: 2.3

The CuraEngine process receives transformed geometry from Cura separately from the slicing settings.

@ahoeben Thanks for the reply, how can I do that manually i.e by passing transformed geomoetry directly to CuraEngine ?

The same way you send untransformed geometry to CuraEngine, but first you transform it and save it as a new stl.

Cura does not use the command line to send/receive data to/from CuraEngine, but it uses protocol based on Protobuf to talk between the two processes.
