The on-canvas dynamic-input boxes measured relative X/Y deltas and the polar angle in world axes. They now read in the active UCS plane (via UcsXform::vec_to_ucs on the offset-invariant delta), matching the UCS ortho/polar constraints and coordinate readout. Identity UCS reproduces the world-frame values; absolute first-point fields are unchanged. Co-Authored-By: Claude Opus 4.8 <[email protected]>
