How to Scale an Object’s Linetype in AutoCAD 2014

By Bill Fane, David Byrnes

Linetype scale controls the display of dash-dot linetypes in a drawing in AutoCAD 2014. Some linetypes that you assign to a layer or an object directly might not look correct on every object based on the drawing’s current linetype scale. The problem with the linetypes is that the dashes and gaps are not always noticeable on every object because of the object’s size or the way the object was drawn.

To fix this problem, you can change the object’s linetype scale that is normally set to a value of 1. The object’s linetype scale is used as a multiplier with the drawing’s linetype scale factor. If you change an object’s linetype scale factor to 1.5 and the drawing’s linetype scale factor is 12, the linetype applied to the object is actually displayed with a linetype scale of 16 (1.5 x12).

Follow these steps to scale the object’s lineweights:

  1. Start a new drawing by using the standard acad.dwt or acadlt.dwt template.

  2. Create a layer that uses the Hidden linetype and set this layer to be current.

    If you don’t feel like creating a new layer, you can always simply set the linetype for Layer 0 (zero) to hidden.

  3. Set the limits to be from 0,0 to 100,100.

  4. Enter Zoom and press Enter. Then enter A and press Enter to zoom to the limits you set.

  5. Start the Line command, and type coordinates to draw a line from 10,10 to 70,70.

    Hey, what happened? That doesn’t look like a hidden line! Well, it is. The problem is that the line is so long and you’ve zoomed out so far that the individual spaces and dashes have all merged into one. The bigger problem is that if you were to plot this drawing to fit an A-size (81/2 x 11) sheet of paper, the line would look just as it does onscreen.

  6. Start the LTScale (LineTypeScale) command and enter 20.

    Ah, that’s better! You need to apply a plotting scale of 1:20 to fit the line on the paper, but then everything scales down, including the spaces and dashes in noncontinuous lines. The LTScale command with a value of 20 tells AutoCAD to make the dashes and spaces 20 times longer so that they scale down properly when you plot.

  7. Start the Line command, and type coordinates to draw a line from 30,10 to 100,80.

    The new line should look just like the first line you drew.

  8. Select the second line you drew and right-click. Choose Properties.

    The Properties palette is displayed.

  9. On the Properties palette, click in the Linetype Scale field and enter 2.

    The display of the linetype for the second line is displayed at a scale of 40.
