When you are in Model-Space, and place a dashed line, you may not see the dashed line. In order to see the dashed line, you need to adjust the LTSCALE (Line Type Scale). The scale factor that you set when you did MVSETUP established the drawing scale factor and knowing the scale factor will help your linetype to appear correctly.
As a general rule: the LTSCALE should be set to half of your drawing “scale factor” in order to see your dashed lines to appear correctly. In the animated picture, my drawing “scale factor” is set to 48 so I set my LTSCALE to 24 and then I was able to see my dashed lines in model space.
Drawing Scale Factors available in MVSETUP:
- (480) 1/40″=1′
- (240) 1/20″=1′
- (192) 1/16″=1′
- (96) 1/8″=1′
- (48) 1/4″=1′
- (24) 1/2″=1′
- (16) 3/4″=1′
- (12) 1″=1′
- (4) 3″=1′
- (2) 6″=1′
- (1) FULL
I then went to a layout tab and noticed that my dashed line did not appear correctly in the viewport. So I hover the cursor over the viewport and then entered MS <enter> to activate that viewport and am now in Model Space. While in the viewport, I set try setting 2 variables “MSLTSCALE” & “PSLTSCALE.” After setting the variable, I entered RE <enter> to regenerate the drawing so that I can see the changes. To be honest, I try these two variables until one of them works and usually the PSLTSCALE variable works. And I change the variable to the opposite of what it was et to. So either <0> or <1>.
- These variables are either On or Off – <0> (zero) = off, <1> = on
Here is a description for the variables:
- Scales linetypes displayed on the model tab by 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 is set to 0 when you open drawings created in AutoCAD 2007 and earlier.
- Controls the linetype scaling of objects displayed in paper space viewports.
- 0 No special linetype scaling. Linetype dash lengths are based on the drawing units of the space (model or paper) in which the objects were created. Scaled by the global LTSCALE factor.1\Viewport scaling governs linetype scaling. If TILEMODE is set to 0, dash lengths are based on paper space drawing units, even for objects in model space. In this mode, viewports can have varying magnifications, yet display linetypes identically. For a specific linetype, the dash lengths of a line in a viewport are the same as the dash lengths of a line in paper space. You can still control the dash lengths with LTSCALE.
- When you change PSLTSCALE or use a command such as ZOOM with PSLTSCALE set to 1, objects in viewports are not automatically regenerated with the new linetype scale. Use the REGEN or REGENALL command to update the linetype scales in each viewport.
