How to Plot a BricsCAD Layout at 1:1 Without Changing Viewport Scale
In a normal BricsCAD paper-space workflow, the Layout represents the real sheet and should be plotted at 1:1. The viewport controls the drawing scale inside that sheet.
BricsCAD Model Space Plotting to Scale: Beginner Workflow
BricsCAD can plot directly from Model Space, but the workflow is less forgiving than a Layout. You must deliberately choose the plot area, paper and plot scale.
BricsCAD Viewport Scale: Set and Verify CAD Scales in Layouts
Viewport scale controls how Model Space is shown through a BricsCAD Layout. Setting it correctly lets the sheet itself remain at 1:1 while different views use different engineering or architectural scales.
