Currently in Autodesk Takeoff, calibration applies a single uniform scale to both horizontal and vertical directions. This creates major limitations when working with drawings that intentionally use non-uniform scales, such as retaining walls, elevations, or detail views that are stretched horizontally but compressed vertically to fit on one sheet. A common real-world example is a retaining wall elevation where: The horizontal length may be drawn at 1" = 20' The vertical height may be drawn at 1" = 5' Because Autodesk Takeoff only allows one calibration scale per sheet or viewport, it is impossible to accurately measure both length and height on the same drawing. Current Impact: Vertical measurements become inaccurate when horizontal scale is calibrated correctly, and vice versa Users are forced to perform manual conversions outside the software This introduces unnecessary risk of error and reduces confidence in takeoff accuracy Competing tools and real-world workflows rely on interpreting non-uniform scales correctly Proposed Solutions: Independent X and Y axis calibration The ability to define custom horizontal and vertical scales Or allow multiple calibration regions on a single sheet This would significantly improve takeoff accuracy for elevations, retaining walls, utility profiles, and other non-uniform scaled drawings.
