How to change the background color from dark to light in BricsCAD?

ByCADbrief Staff

Short Answer

Yes — in BricsCAD, you can change the background color from dark to light by opening SETTINGS and switching the drawing window background color in the program settings. This is the most common professional method because it updates the workspace directly. Limitation: some interface elements may still keep their own theme colors.

What You Need to Know Before

Warning: changing BricsCAD to a light background can make white or very light-colored layers hard to see, especially in legacy drawings that were created for a dark model space. Plot output does not change, but on-screen readability often does.

How to Change the Background Color from Dark to Light in BricsCAD

  • Command: SETTINGS

  • Shortcut: [no default alias in most installations]

  • Quick Steps:

    1. Type SETTINGS on the command line, then press Enter.
    2. In the Settings dialog, go to Program Options > Display > Colors and locate the Model background setting.
    3. Change the background color to White or a light color, then click OK or close the dialog to apply it.

Variables & Settings

  • Key Setting: Model background

  • Expert Setting: This setting controls the background color of model space only. If paper space still looks different, check the layout background color separately in the same Colors area, because model space and sheet layouts can use different background settings.

Why it Fails

  • Cause 1 (Geometry): white, yellow, or other light-colored entities may visually disappear against a light background even though the geometry is still present.

  • Cause 2 (Layers/Locks): locked or faded layers can become even harder to read after switching to a light background, especially if layer colors are already low-contrast.

  • Cause 3 (Command/Logic): users sometimes change the application theme instead of the drawing area color, which does not always switch the actual model space background from dark to light.

Quick Fix & Best Practice

  • Quick Fix: run SETTINGS, change Model background to white, then adjust problem layer colors in LAYER for better contrast.
  • Manager’s Verdict: use a light background when your office standard, screenshots, or documentation workflow benefits from paper-like display; avoid it if your drawings rely heavily on white or pale layer colors designed for dark model space.
