Line type appearance for different scales

[aizzaac]

Hi

 

I use many types of lines for drafting. I have to set a Linetype Scale depending on the scale asked by the client. For example if the client asks for 1:100 then my lines are set to 0.5. But if he suddenly changes her/his mind and asks for a 1:250 scale I have to change all the Linetype Scales to 2.5.

 

Is there something like "Annotation scale" for lines? So whenever I change the drawings scale my lines can be seen as they must be.

Yes, set everything to "1" and AutoCAD will automatically scale linetypes correctly in both Modelspace and Paperspace when the Annotation scale is changed using the scale list (CANNOSCALE) (Regen may be required to update display)

 

LTSCALE = 1

CELTSCALE = 1

MSLTSCALE = 1

PSLTSCALE = 1

 

*Note: LTSCALE does not have to be "1", many prefer 0.5

The following settings should get you there.

 

MSLTSCALE = 1

LTSCALE = 0.5 (default is 1 and some companys want it left that way)

PSLTSCALE = 1

CANNOSCALE = (DESIRED PLOT SCALE, set with anno scale drop down

Thanks. I still can't believe it can be that easy.

I am in charge of the telecommunications drawings. I use lines for CCTV, Data, Voice, etc.

So, I only have to set the parameters you have mentioned and my won't have to change the Linetype scale ever?

Okey... but once I use cannoscale, What scale do I have to set in the layout model to get the same "view" of my lines as it is seen in the model space?

Correct, unless you have existing objects in your drawing(s) which have had their individual LTSCALE property overridden.

It's not important that they be displayed the same to print/plot properly, but using the same scale (Cannoscale) in Modelspace as Layout/Viewport will make them display the same.

 

REGEN is sometimes required in Layouts to cause the linescale to regenerate, and always required in Modelspace to update linescale display.

When I use these parameters (in model space) my lines look the same eventhough the architecture and the blocks change size.

 

CANNOSCALE PLOTSCALE

1:200 1:100

1:75

1:50

 

 

But when I work in the layout space (for creating a viewport and plotting from there) my lines change their appearance (whenever I change the viewport scale)

 

CANNOSCALE (model space) VIEWPORT SCALE (layout space) PLOTSCALE (layout space)

1:200 1:100 1:1

1:75

 

1:50

 

Why in the layout space does this happen? I mean: why can't the lines keep their appearance meanwhile the blocks and the architecture change in size, just as in the model space?

 

I use the layout space to create viewports and put in there the xrefs of the legend and the logo of the company, name of the project, etc.

 

Thanks

You can but I don't see how that's desireable. Say you were drafting with a paper and pencil, when you draw a "dashed" line, you would probably draw a segment about 1/8" long, then skip 1/8" then draw another line 1/8" long and repeat as long as necessary... right? It wouldn't matter if you were drawing a small part at full scale, or a sight plan at 1/128 scale, you'd still use your pencil to make "dashed" lines 1/8th by 1/8th. A "dashed" line should be 1/8 x 1/8 when printed, whether it's on a 8 1/2 x 11 sheet, or 36 x 48, and regardless if the scale is 1:1 or 1:1000. That's exactly what AutoCAD does automatically when MSLTSCALE and PSLTSCALE are "1".

 

As for why Modelspace requires a REGEN and Paperspace/Layouts REGEN automatically, I have no idea. Both should update immediately and automatically when the CANNOSCALE is change.... IMO.
