Manual shop drawing errors that pass internal review still surface as fabrication rework once panels reach the shop floor — and by then, the cost of correcting them has already multiplied several times over.
Why Passing Review Does Not Mean an Error-Free Drawing
Shop drawings produced manually from a 3D model involve a transcription step — someone translating the model’s geometry into 2D drafting output. This transcription can introduce errors that are subtle enough to pass an internal review focused on overall drawing completeness, without necessarily catching a specific dimension that drifted during manual translation from model to drawing.
Where These Errors Actually Get Caught
Because a subtly incorrect dimension does not make a drawing look obviously wrong, this class of error typically survives internal review and only becomes visible once fabrication has begun — when a panel cut to the drawing’s stated dimension does not actually fit the installation condition the 3D model represented.
Why This Timing Makes the Error Far More Costly
An error caught during drawing review costs a correction to the drawing itself. An error caught during fabrication costs the material already cut, the labor already spent, and the schedule delay of re-fabricating a corrected panel — a substantially higher cost for exactly the same underlying transcription mistake.
Removing the Transcription Step Where These Errors Originate
After tracing how manual transcription errors slip past review and reach fabrication, the fix is removing the transcription step itself, rather than trying to catch transcription errors through more rigorous manual review. DASH’s automated, CAD-accurate 2D extraction pulls directly from the 3D model, eliminating the manual translation step where dimensional drift most commonly enters a shop drawing set.
