Open the General Arrangement drawing.
In the example below, the color of the visible lines is yellow and we would like to change it to orange in all the views.
Type "qselect" on the AutoCAD® command line.
In the "Quick Select" dialog box, choose "Layer" for Properties and "Beams" for Value for the layer name.
(In our example, all the beams are on the "Beams" layer, which also exists in the 3D Model.)
Then click OK. All elements in the "Beams" layer are selected.
Use the contextual menu and select "Advance Beam Properties".
Change the "Visible line color" to, for example, "Orange" (color 30), and press Enter.
All the visible lines of the "quick-selected" elements are changed to orange.
