The weight of a line refers to its thickness on the printed page and is described in absolute terms as a fraction of a unit, often 1/100th of a millimeter or 1/1000 of an inch.
You can specify the Line Weight Scale by defining the denominator and the unit used in this fraction in the Page Setup dialog. See "Page Setup Dialog".
In Chief Architect, line weights are assigned to objects, patterns or layers using whole numbers that correspond to the numerator of this fraction.
Your preferred line weights and line weight scale can be saved in your template plan and layout files. See "Template Files".
The method for changing the line weight for a particular object depends on the object and the type of view.
When a view is sent to layout, line weights may be affected by the drawing scale selected for the view. This occurs when the layout view's scale is different from the drawing scale of the original view.
For example, assume that you have an object in a view with a line weight of 20, and that the view's drawing scale is 1 mm = 50 mm.
You can specify the drawing scale for any orthogonal view by opening the Page Setup dialog while in that view. See "Page Setup Dialog".
For any layout view, you can specify whether the original line weight is maintained or not in the Send to Layout and Change Scale dialogs. See "Send To Layout Dialog" and "Rescaling Views".

Note: Under most circumstances, you should select Use Layout Line Scaling when sending views to layout.

Line weight scaling affects both line weights and line styles and can be particularly noticable with dashed line styles.
In the following image, the same floor plan view has been sent to layout twice, at two different scales. The view on the left was sent at the same scale as the original view,
1/8" = 1'. The view on the right was sent at 1" = 1', or magnified eight times, to show an area of the plan in greater detail.
Because the view on the right was sent to layout at a scale other than that of the original, it is subject to layout line scaling.
The solid lines representing walls, cabinets and doors are rescaled to be eight times thicker than in the original view.
Similarly, the dashed lines representing the door jambs are rescaled so that the dashes and the spaces between them are eight times larger than in the original view.
If Use Layout Line Scaling is enabled, line weights are no longer scaled and the dashed lines display at the same size as in the original view.
Because the view in this example is scaled eight times larger in this case, the dashes and line weights look relatively small and fine when Use Layout Line Scaling is enabled. Were the view rescaled to be smaller instead, the line weights would look relatively large and thick.
Line weight and print scaling are subject to the limitations of the printer being used. For example, you will not be able to see the difference between a line that is 1/150th of an inch wide and one that is 1/300th of an inch wide when they are printed using a printer that prints 150 dots per inch (DPI).
That is, a CAD line with a line weight of 1 will look the same as a CAD line with a line weight of 4 when the Line Weight Scale is set at 1 = 1/600th of an inch and you print to a printer capable of 150 DPI.
When plans and layouts created in prior versions of Chief Architect are opened in Version X1, they assume the Page Setup settings, including the Line Weight Scale, specified in the Preferences dialog. See "Text & Page Setup Panel".
When working with legacy files, using a Line Weight Scale of 1 = 1/X, where X is the DPI of your printer, will produce the most faithful translation from the previous version.
