Use `GetTrimmedLoft()` for the previous behavior (with UV cutting at profile positions). This affects `CCPACSWing` and `CCPACSFuselage` (and their segments). [#994](https://github.com/DLR-SC/tigl/issues/994) + +### Features +- Add optional UV profile cutting to `CTiglMakeLoft` via `setEnableProfileCutting(bool)`. When enabled, creates seams at each profile wire position for consistent UV parameterization. Wing and fuselage builders now build both trimmed and untrimmed lofts on demand.
