I would like to understand how the Line Weight Scale and line weight scaling options work. What do these do and how can I best implement them?
When I try to send a view to layout, I keep getting this error message: "The line weight scale in your layout is not the same as in the view being sent to layout. You should change them to be the same or the resulting line weights will be lighter or heavier than expected. This can be corrected in the Drawing Sheet Setup dialog."
What does this mean?
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.
In Chief Architect and Home Designer Pro, line weights are assigned to objects, patterns, and layers using whole numbers that correspond to the numerator of this fraction. You can specify the Line Weight Scale by defining the denominator and the unit used in this fraction in the Drawing Sheet Setup dialog.
While the default line Line Weight Scale and line weights will work for most normal drawing practices, you can specify your own values if you so desire.
The method for specifying an object’s line weight depends on the object and the type of view.
In order to produce predictable, accurate printed drawings, it is necessary that the Line Weight Scale located in the Drawing Sheet Setup dialog be identical in both the layout file and in the original view sent from the plan file. If they are not, you may receive an error message mentioning the variance, in which you will want to set them to be the same.
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 Drawing Sheet Setup dialog while in that view.
For any layout view, you can specify whether the original line weight is maintained or not in the Send to Layout dialog and Change Scale dialog.
In order to produce exact line weights, a Vector View must be sent to layout using the Plot Lines option.
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.
Setting an object’s or group of objects’ line weight to zero causes the lines to print as thinly as possible.
