Drawing colors

December 6, 2024

Struggling with stubborn entity colors that won't change despite your best efforts in CAD drawings?

Have you ever had an entity on your drawing that you can not change the color of? Or have you ever added an entity to the drawing and it is an unexpected color and you can seem to change it to the desired color?  Then read on.

There are several places you can change the color of entities and there is a hierarchy which controls which color is used.

Most of us are familiar with the first 2 but often users are not aware of the third.

1.   System options

Access: Tools-> options-> System Options tab-> Colors section

2.  Layers.

Layers will override system options colors

Access: View-> Toolbars-> Turn on the layer toolbar.

The toolbar indicates which layer is activated so any new entity added will be in this color.

Click layer properties for the list of layers and their colors.

3.  Line format.

This overrides both System Options Colors and Layer Colors.

This is the one that sometimes eludes users

Access: View-> Toolbars-> Line Format toolbar-> Line Color

You can change the color of any entity by selecting it and then selecting the color here.

If you select a color without any entity selected then new entities created will be in this color

If you tick default it will use the layer color or color in the system options

Also on the Line format toolbar, you will find the Color display mode.  This will switch between the line format colors/layer colors and the system option colors.
