This setting becomes especially important when you go to plot, since lines that appear dashed in Model Space may appear solid in Paper Space if their LTSCALE isnt exactly correct.

Maintaining the integrity of your dashed lines is integral to the accuracy of your drawing.

Why Because CAD standards call for specific lines to be dashed in unique ways in order to distinguish them from other linework.

Examples include fences, property lines, utility lines, mainline pipe, and pipe sleeves.

You can often resolve this issue with our Reload All Linetypes ( REAL ) tool.

Running the REAL tool will reload all linetypes from the current library.

Still having issues with making your linetypes look right Read on.

If you change the LTSCALE, you change the appearance of the linetype in Model Space.

As a result, lines that appear dashed in Model Space that is, in your working drawing may appear solid in Paper Space.

The gap reads as.25 drawing units, and the dashed segment is.5 drawing units.

For this reason, youll want to set your LTSCALE value to account for the scale you plan to set for your viewport, which will allow you to see the linetypes properly in Model Space.

The example below shows two different LTSCALE settings, which result in vastly different linetype appearances.

We do not recommend using Annotative Scaling unless youre already familiar with it.

This is our recommended setting if you are not familiar with Annotative Scaling.

Layout sheets should be kept in separate drawings to keep PSLTSCALE set to 1 in Paper Space.

You can leave this setting as 1:1 if youre not using Annotation Scale.

If you plan on using Annotation Scale and you want the linetypes to reflect appropriately in Model Space, set MSLTSCALE to 1.

All linetypes will scale appropriately and be a consistent size.

Dont fall into this trap; its actually a very simple method that requires minimal effort.

The scale you set will be your Dimscale, which will match your LTSCALE when you are in Model Space in this drawing.

In that new drawing, open the Xref Manager by typing XREF in the Command line and pressing Enter.

In the example below, we are Xrefing the original drawing, My Site Plan, into the new drawing, Drawing 1.

Type PSLTSCALE in the Command line, and type 1 when prompted to Enter a value.

That is, we have an LTSCALE of 1 in Model Space, and a PSLTSCALE of 1 in Paper Space the default linetype scale setting, and an AutoCAD best practice.
