How to Enable Dark Theme in SOLIDWORKS

Contents

SOLIDWORKS does not use one single dark-mode switch in every version. The practical setup is usually done from System Options > Colors, where you can change the background appearance and color scheme so the modeling area is easier on your eyes.

This is useful for long CAD sessions, low-light offices, and users who prefer less glare while modeling.

SOLIDWORKS color settings for dark theme — Dark theme settings are mainly handled from the Colors options.

Open the Colors options

Open SOLIDWORKS.
Click Tools > Options.
Choose the System Options tab.
Select Colors.
Review the background and color scheme settings.

System Options Colors page in SOLIDWORKS — The Colors page controls the viewport background and many interface colors.

Set a dark background

Look for the background appearance setting. Depending on the version and setup, you may be able to choose a dark background, plain background, gradient background, or custom top and bottom gradient colors. Choose a darker setup that still leaves sketches, dimensions, edges, and selection colors readable.

Dark background option in SOLIDWORKS — Choose a dark background that keeps sketch and edge colors visible.

Adjust color scheme settings

After changing the background, inspect sketch colors, dimensions, annotations, selected items, and temporary preview colors. A dark viewport is only useful if you can still read the model clearly. If blue, gray, or black elements disappear into the background, adjust those colors before settling on the theme.

Save or reuse the setup

If you manage multiple computers, document the settings or use company CAD standards so users have a consistent interface. Some teams prefer a neutral gray background because it works better for screenshots, training, and drawing review.

Troubleshooting dark theme problems

Sketch lines are hard to see: adjust sketch and selected-item colors.
Dimensions disappear: change annotation or dimension color settings.
Screenshots look too dark: use a neutral background for documentation.
The setting does not match another computer: compare System Options and version differences.
Performance changes: update graphics drivers and check display settings.
