The linetype scale for components of AEC objects works with the AutoCAD linetype scale specified in the LTSCALE variable to control the linetype of AEC objects. The default value for linetype scale of all components of AEC objects is 1.0. This value is multiplied by the current value for LTSCALE to produce the linetype scale of object components.
For example, if the LTSCALE value is 48.0, and the linetype scale in the display properties of an object is 1.0 for an object component, then the linetype scale of the component is 48.0. If you change the linetype scale in the display properties to 2.0, the linetype scale of the component is effectively 96, or 2.0 x 48.
