All of my line styles appear to look the same, as solid, instead of dashed, lines. They appear indistinguishable from each other. Why?


Line weight scaling affects both line weights and line styles, and can be particularly noticable with dashed line styles.

To adjust Line Weight Scaling

  1. Select File> Print> Drawing Sheet Setup  from the menu to open the Drawing Sheet Setup dialog.

  2. Near the bottom of the dialog box, uncheck the Use 1 for all line weights (Home Designer compatibility) box under Advanced Line Weight Options, then click OK.


The default line weight scale of 1=1/100mm makes it easy to meet many professional drawing standards. In most cases, this scale will produce positive results using any printer or plotter and should not be changed. 

Checking the option for Use 1 for all line weights is not normally recommended. The reason to check this is to have the program specify the line weight scale, and adjust it, to maintain line thickness and dash size when the drawing scale is changed.

This feature was added for better interoperability between the Chief Architect professional program and the Home Designer software.

Plan files originally created in one of the Home Designer products have Use 1 for all line weights checked by default.
