line scale is making me go crazy

[CADkitt]

I've set:

(setvar "PSLTSCALE" 1)

(setvar "LTSCALE" 10)

(setvar "MSLTSCALE" 1)

I really have no idea what psltscale and msltscale does because if I change ltscale I set the line scale. So why should I use the ps en ms ltscales? I played around with the settings and the only thing that really did something is LTscale.

i have read this: http://www.caddmanager.com/CMB/2009/06/ltscale-psltscale-celtscale-and-msltscale/ and really I still don't get it...

 

But, all I want is that linescale is just 1 when I print a layout why the hell is this so hard to do? Every other CAD program does this.

Why is LTSCALE set to 10 and not 1?

[CADkitt]

If i set a hidden line it to 1 it just a cont. line, I even had to set it to 500, and sometimes only 10 and well @!#@$$ What is the point of linescaling in layouts any way? There is no line scaling in Solidworks or Pro/e and i never needed it in those programs.

In my view it is all pointless, the only correct scale is 1:1 on print format. If you have a hidden line you want it to show up as a hidden line on your print not as a continues line.

Heres my go at an explanation:

http://thecadsetterout.wordpress.com/2010/05/11/autocad-line-type-scales/

 

MSLTSCALE only effects how the lines look in Model space when you change the Annotation scale (You need to do a regen to see the change). PSLTSCALE affects weather Autocad will scale your linetypes to suit the viewport scale while in paper space. Tip: Hit F1 for help!

 

Autocad works differently to Solidworks and Pro/E - Inventor doesn't need Linetype scale either.

[CADkitt]

So my conclusion is:

pltscale on 1 and ltscale to whatever "looks good"?

Which is pretty stupid to set something to look good, where not in an art business. I guess you can calculate the correct ltscale?

But how? Any one any idea?

 

Great post btw Pable was much clearer then that other blog post.

Ta Marjin,

 

LT scale dpends on what your drawing standards say. In general 1 should be fine for everything. If you need a different spacing of dots and dashes you can change the linetype. If you are conforming to the ISO standards than the LT scale should be set to match the lineweight. ie. 0.25mm Lineweight = 0.25 LT Scale (or Celtscale!) for that line

The good thing about AutoCAD is that it gives us so much control over the environment. The bad thing about AutoCAD is that it gives us so much control over the environment.

 

It actually is easy.

 

(setvar "PSLTSCALE" 1)

(setvar "LTSCALE" 0.5)

(setvar "MSLTSCALE" 1)

 

Set the cannoscale in modelspace to your eventual plot scale.

 

It is ok to let LTSCALE to get the linetypes to looking how you want them to look, unless there is a company standard where you work then you would go by that.

 

Sometimes when drawing small parts the hidden lines won't show at all unless you set ltscale to a smaller value. Larger drawings, like buildings, a ltscale of .5 or even 1 will work and let the hidden linetype show.

In my business bolts like M36 are common. So I can have a beam of 26 meters and 2 meters high or a part of a cylinder that is 200mm in diameter. So correcting ltscale every time gets ignored by a lot of users .

This particular user does not ignore ltscale. I leave it set to "1". Most of the time I do not have to touch it at all.

I have set up Tools on my toolpalettes for my most frequently used line types, including LT scale. I leave LTSCALE alone too... It would be great if you could set LTSCALE by Layer... Maybe one for the Wish list...

I would have said it has to do with what scale you intend to plot your drawings out at. I would use PSLTSCALE 0, MSLTSCALE 0

 

either use LTSCALE or CELTSCALE to control the line type.

 

Setting LTSCALE to 1 - things will look right at eventual plot scale 1:1

 

setting LTSCALE to 40/50 - things will look right at 1:50

 

You can also use LTSCALE 1.

Then use CELTSCALE (Current element) to whatever you want i.e. 10, 50 to look right on paper.
