Issue:
This article describes how to work with the MSLTSCALE and PSLTSCALE system variables.Create Linetype with Leader Arrow, Used to Show Direction of Flow. I am trying to create a Linetype in AutoCAD. I am wanting to use the Linetype to show Medical Gas Lines and their Direction of Flow. I want the line to behave similar to other Default AutoCAD linetypes. Having the arrows follow the angle of the line. This document provides instructions for using text styles in complex linetypes. It discusses the effects of the LTSCALE and CELTSCALE system variables on the font characters and recommends steps to get the best results. Complex linetypes are custom linetypes that can contain embedded shapes or text. Before you create complex linetypes using text, consider how the font settings, scaling,.
Causes:
This can be the result of the MSLTSCALE and/or PSLTSCALE system variables not being set properly.Solution:
Starting with AutoCAD 2008, linetype scaling in model space is controlled by the variable MSLTSCALE and in paper space with PSLTSCALE.
The MSLTSCALE system variable controls whether or not linetypes displayed in the model tab are scaled based on the annotation scale.
- 0 = Linetypes displayed on the Model tab are not scaled by the annotation scale.
- 1 = Linetypes displayed on the Model tab are scaled by the annotation scale.
Note: MSLTSCALE Overrides LTSCALE and CELTSCALE in model space, but it doesn’t effect paper space, so it won’t change how geometry looks within the viewports.
The PSLTSCALE system variable controls the linetype scaling of objects displayed in paper space viewports.
- 0 = No special linetype scaling.
- 1 = Viewport scaling governs linetype scaling.
For example, if a line set to use the HIDDEN linetype displays correctly in model space and in paper space by setting MSLTSCALE to 1, AutoCAD will re-generate the linetype by the annotative scale after using the REGEN or REGENALL commands. The line will be displayed in model space line as shown in Image 1 and in paper space as in Image 2.
