I am working on floor two, and I want to have the first floor referenced. By default, the reference floor lines display in red. How can I change that color?
You can specify that the reference floor display in a different color on the Layer Display Options dialog.
To specify the reference floor color
Select Tools> Layer Settings> Layer Set Management from the menu.
In Chief Architect X5 and prior, navigate to Tools> Display Settings> Layer Set Management.
In the Layer Set Management dialog, click on Reference Display Set in the list of Available Layer Sets, then click the Define button.
In the Layer Display Options dialog, notice that the Reference Display Set displays in the top left corner of the dialog.
Click on a layer name in the alphabetized list to select it, then click the Color bar to open the Color Chooser dialog.
In the Select Color dialog, specify the color that you would like to use to represent the selected layer, then click OK.
Repeat steps 5 and 6 as needed to customize the display of Reference Display.
If you would like to specify a single color for all layers in the Reference Display Set, click the Select All button in the bottom left corner, then click the Color bar to open the Select Color dialog and specify the desired color.
The button will show "No Change" for the color when all layers are selected as some layers have a different color. You will still be able to click the Color field and specify a new color for all layers.
