scale factors in modelspace, to suit different scaled viewports in paperspace

I think I am complicating things - a steer please.

In modelspace, architectural schematic plans sections elevations which, when viewported into paperspace drawings, are scaled to 1:100. I therefore work in modelspace with Current object scale = 1, global scale factor = 100. This makes dashed lines etc reproduce at legible scale in a drawing at 1:100.

What about when I move on to details, which in paperspace are scaled to 1:5? At present I start a new file with Current object scale = 1, global scale factor = 5. This makes dashed lines etc reproduce at legible scale in a drawing at 1:5.

Isn't there a way to achieve this, while keeping both the schematic and the detail drawings in modelspace on the same, single file?

Even the above system fails when I want to scale one elevation of the schematics at 1:50, or foundation details at 1:10.

It is overcomplicated. Draw everything at 1:1 in modelspace, then set the scale of the viewports in paperspace to suit the needs of the detail or section.

manipulate the line type scale (also hatch scale) to acheive proper looking lines and hatches.

Don't mean to be stupid, but can you spell that out?

line type scale = ltscale = Global scale factor in Linetype manager - right? what exactly do I manipulate, where? select the relevant elements in modelspace and change ltscale - but that changes whole of modelspace.

another thing - what's that tickbox in Linetype manager - use paper space units for scaling? I have to leave it unticked, otherwise dashed lines, batting etc which look right in modelspace display at weird scale in paperspace - even when both ltscale and celtscale are 1 in modelspace.

Hmmmm. I misinterpreted your post. I thought I read that you were drawing details in modelspace that were scaled in modelspace. Mia Culpa:oops: I was speaking in a generic sense because there are so many ways to screw up line type scales in autocad, I didn't want to go off somewhere. I am not all that successful in controlling them myself. It seems that you are already doing what I was trying to suggest anyway.

I usually scale my lines in modelspace to look good in the smaller scale drawings such as floorplans, and just live with the longer dashes in the sections and details. I'm not that picky, and nobody getting my drawings is at all interested in paying extra for works of art.

Can't you just change the linetype scale in one of your viewports?

No, I don't mean by using the LTSCALE system variable.

You can change the Linetype Scale of an object in Properties.

Doesn't linetype scale mean LTSCALE? Do you mean change CELTSCALE of individual elements in modelspace?

I still don't understand that tickbox in Linetype manager - 'Use paper space units for scaling'.

Call it anything you want I just know for a fact that if I have two viewports showing different parts of the drawing I can change the linetype scale of an object in one viewport even if it uses the exact same linetype as another object in another viewport. So, for example, I can have a box in viewport 1 and viewport 2, each done with the Dashed2 linetype. In viewport 1 the linetype scale can be 1.0 and in viewport 2 the linetype scale can be 2.0.

Ok, that's Linetype scale as set for individual elements by the Properties palette - which I now see is same as commandline CELTSCALE, not LTSCALE.

What I want is to draw one box in modelspace complete with hatching, batting linetype and dashed linetypes

Then show that box at 2 different scales in 2 different viewports, like

the whole of it scaled at 1:50 in one 'layout' viewport

and one corner of it scaled at 1:5 in the other 'detail' viewport

and have hatching, batting and dashes display at appropriate scale in both viewports

but because the same modelspace elements are used/displayed in both viewports, each one can only have one Linetype scale.

So what is that tickbox in Linetype manager - 'Use paper space units for scaling'?

I keep thinking it's the answer to this, but can't make it work.

It's self-explanatory.

When you enable that feature PSLTSCALE is set to 1. Disable that feature and PSLTSCALE is set to 0.

What are your MSLTSCALE and PSLTSCALE veriables set to?

It's self-explanatory.

See if that clears it up a bit.

This is what I normally do also.

Bigal did make a post a couple of months ago that does what the OP wants; http://www.cadtutor.net/forum/showthread.php?63358-Layer-Queries&p=432299&viewfull=1#post432299

Thanks, I didn't find that blog post that helpful in particular although it looks like a helpful site.

How can you do this via the properties panel? It always changes the linetype scale in model space and thus in all viewports for me, do you know if there is a system variable I may need to change for that?

I've done it countless times so I never give it a thought as to how/if the ability to do so is controlled by a system variable. I'd have to go through my settings then compare them to yours or the OP's.
