Global scale factor - model space & paper space

I'm hoping someone can enlighten me as to how to set-up the drawing so I don't have to change the ltscale between model space and paper space in order to get dashed lines to read?  What is the ideal global scale factor for an architectural drawing in model space?  I've always learned 1.

Thanks to Bob_Zurunkle:

Are you on 2008 or newer? If so, you start in modelspace with CANNOSCALE set to 1/4" = 1'-0", or whatever overall scale you use the most. Most of my overall drawings will use 1/8" or 1/4" scales.
Next, remove all linetype scale overrides and set LTSCALE, MSLTSCALE, PSLTSCALE & CELTSCALE all to 1.
Next, test out the different linetypes in modelspace to see if certain ones work for you for most cases. AutoCAD ships with 3 variations of most linetypes. This will probably not work for the batting linetype, but will be a good drawing practice that once you get it set, you may want to create a template from it. Also, it may not appear to work in your current drawing -- you may want to try a regen, and if that doesn't work, you may want to start with your clean template, do all of the above steps, and then COPYBASE the contents of the existing drawing into the new one.

Now, in modelspace you can adjust the linetype scaling of the batting linetype to fit within your wall. It may be a different scale from one wall width to the next though. If the other factors are all set as noted above, then what you see in modelspace should be what you see in any viewport in paperspace.

Before 2008, you would override the linetype scale in modelspace first, then apply a global adjustment by the inverse of the viewport scale, but this only applies to one viewport scale (so other viewports with different scales won't show the linetype the same). By changing PSLTSCALE to 1, you are saying you want paperspace to detect it's scale and adjust how the linetype is viewed accordingly, making it view the same in all viewports no matter what their scale. When you use this, you set LTSCALE to 1 (this is the global linetype you are setting).

So it is still best to start with everything set to 1, and test out your linetypes in modelspace to see what looks best to you. If you are on 2008 or newer, then adjust your CANNOSCALE on typical linetypes like hidden, center, phantom etc and pick one of the 3 of each that works best. This is to avoid overriding the linetype scale. But on 2007 or older, you have to find which scale override works best for you, and then set your CELTSCALE to that scale. After either of these that fits your case, then draw a batting line and adjust it's scale to suit you, using the override.

I hope I haven't been too confusing lol...

Dang I',m wordy :smileytongue:

 

To simplify, set LTSCALE, MSLTSCALE, PSLTSCALE & CELTSCALE all to 1.

Next, in modelspace, set CANNOSCALE to 1/4" = 1'-0" if that's the eventual scale of a paperspace viewport -- or 1/8" if that's the scale, etc.

Next, pick a linetype and test it out. If it doesn't suit, try another etc. If nothing suits, then make your own.

If it's an existing drawing, select everything and set all linetype scales to 1, and then adjust from there...

 

CANNOSCALE does not change the modelspace scale away from 1:1. It simply affects how linetypes are viewed in modelspace -- kind of a preview of how it should look in a paperspace viewport of identical scale. It also affects how other annotative objects look when they are created/inserted in modelspace.

If by some odd chance my nattering was useful -- that's great, glad to help. But if it actually solved your issue, then please mark my solution as accepted :smileyhappy:

There's two or three trying to do this right now and one of them keeps telling me his drawing is changing scale when he changes CANNOSCALE.

All we can do is offer advice.

 

And I'm hoping to get waht you wrote published in the CKB.

Sorry - worked around it for a little bit but back to driving me crazy.  I'm in the student edition of 2013.  I can't seem to alter the CANNOSCALE in model space, it' reads "1:1" - I've tried a variety of values.

Open SCALELISTEDIT.
Do you see the Scale you want there?

Yes I see the scale option there. I clicked on the 1/4" scale, but cannoscale still reads 1:1.
