Control Linetype Scale

May 20, 2011

     You can set global or individual scales for objects to control the display of linetypes.

     By default, the global and individual linetype scales are set to 1.0. The smaller the scale, the more repetitions of the pattern are produced per drawing unit. For example, if the scale is set to 0.2, five repetitions of the pattern in the linetype definition are displayed for each drawing unit.

     If short segments are too short to display one full linetype pattern, it is displayed as continuous. When the lines are too short to display even one dash sequence, you need to specify a smaller linetype scale. Otherwise, the linetype is displayed as continuous shown as the following illustration:

\


      For polylines, you can use system variable PLINEGEN to control whether a linetype pattern is centered on each segment or is continuous across vertices throughout the entire length of the polyline.

     The Global Scale Factor and Current Object Scale are displayed in the Linetype Manager.

     The Global Scale Factor and Current Object Scale are displayed in the Linetype Manager.The Global Scale Factor value is stored in the system variable LTSCALE, which changes the linetype scale globally for new and existing objects. The Current Object Scale is stored in the system variable CELTSCALE, which specifies the linetype scale for new objects. You can get the displayed linetype scale by multiplying the CELTSCALE value with the LTSCALE value. The linetype scales in the drawing can be changed easily either individually or globally.

      In a layout, you can use system variable PSLTSCALE to adjust the linetype scale in different viewports.


NOTE Setting the linetype scale too large or too small may result in a line pattern looking like a solid line, depending on what the scale view is or at what scale the drawing is printed.

    You can control a new entity's individual linetype scale factor as well as the overall or global scale factor applied to all the entities in the drawing.


To set the current individual linetype scale

  1.   Choose Format > Linetype.

  2.   Click the Show Details button.

  3.   In the Current object scale field, type the linetype scale that you want to make current.

  4.   Click OK.

Command line LINETYPE



To change the global linetype scale

  1.   Choose Format > Linetype.

  2.   Click the Show Details button.

  3.   In the Global Scale factor, type the global linetype scale that you want to change.

  4.   Click OK.

Command line LINETYPE
