INDUSTRIAL PLOTTING & VECTOR DRAWING BLUEPRINT

TECHNICAL DIRECTIVE: SOLIDWORKS-PLOT-B26

This technical standard directive defines the Color-Dependent (CTB) pen style thicknesses, drawing scale calibrations, and high-definition vector PDF font embedding standards for SolidWorks. Make sure you enforce these styles to eliminate vector missing weights.

CORE STANDARD DETAILS

Standard Spec:ISO 128-20 / ANSI Y14.2M / AIA Layer Spec

Scale Mapping:1:1 Model Space to Layout Space Mapping

Font Standard:SHX Vector Fonts (RomanS / Simplex / txt)

REVISION METADATA

Directive Status:APPROVED FOR DRAFTING

Directive Code:REV-PLOT-2026-B

Audited By:BIM Coordinating Comm.

Line-Weight Pen (CTB) Calibration Table

Verified pen weight scaling parameters matching ANSI, ISO, and AIA standard drawing plot style sheets.

AIA Pen Color ID	Plot Pen Thickness	Linetype Mapping	Vector Screen Color	Standard Architectural Use Case
Color 1 (Red)	0.18 mm (Extra Fine)	Continuous (Solid)	255,0,0 (Red)	Hatch boundaries, hidden partitions, center grids
Color 2 (Yellow)	0.35 mm (Medium)	Continuous (Solid)	255,255,0 (Yellow)	Text annotations, dimensions, door swings
Color 3 (Green)	0.50 mm (Thick)	Dashed (Hidden2)	0,255,0 (Green)	Medium structural outlines, dynamic section cuts
Color 7 (White/Black)	0.70 mm (Heavy)	Continuous (Solid)	0,0,0 (Black)	Borders, title blocks, layout sheet borders
