Linetype scale confusion!

[fostertom]

In Acad 2006, I don't get Linetype scales - can someone provide an idiot's guide?

 

In Linetype Manager there's Global scale factor and Current object scale and a 'Use paper space units for scaling' checkbox. In Object Properties there's Linetype scale. How they interact beats me. What's the recommended settings? - architectural, drawing full size in model space.

 

There in model space there's plans/elevations etc intended to be viewed/plotted at 1:100, other ditto intended at 1:50; details intended at 1:5, components intended at 1:20. To make dashed lines legible at these different scales, I have to fiddle the scale settings. Then there's Batting - fiddling the scale settings throws Batting widths out crazily!

Also, read up on LTScale, PSLTScale and CELTScale.

Thanks for the reply. I think I got all that, maybe thought there was more to it.

 

Well, I got clear that LTScale is same as Global scale factor, CELTScale is same as Current object scale, and PSLTScale is same as 'Use paper space units for scaling' checkbox.

 

Looks like there's no solution to my problem? Which is that to view dashed lines legibly in modelspace, I set LTScale to 5 when viewing 1:5-like detail, and to 50 when viewing 1:50-like schematics. That works fine.

 

However that screws up the BATTING linetype, which is unique amongst linetypes in having width, which is governed by LTScale. So BATTING doesn't want to have its LTScale adjusted from 5 to 50, because every bit of BATTING then gets 10x wider than it should be and the drawing's covered with squiggles!

 

All my BATTING is in a layer to itself, so any easy way to apply a reverse scale multiplier to just that layer, or to make that layer immune to LTScale changes?

How about making it a polyline and reducing the global width? Seems a long shot, I admit.

[fostertom]

Wouldn't that just alter the 'lineweight' of the S-bend line, not the overall spread (amplitude?) of the S-bend?

 

I've accepted that Batting's a special faff.

 

On a detail section intended to be viewed at 1:5, LTScale is set to 5 and for insulation 150thk I draw Batting with CELTScale set to 1.5.

 

Where the same section appears (simplified) on a schematic intended to be viewed at 1:50, LTScale is set to 50 and for the 150thk insulation I draw Batting with CELTScale set to 0.15, then it displays right.

 

But when LTScales' set to 50 because I'm working on the 1:50 schematics, it's no good looking at the 1:5 details in modelspace - it's a mass of big squiggles!

 

Any better ideas?

[wannabe]

Copy the object to paperspace and freeze the model space layer in the viewport - after you've put all lines with this lt on that layer.

 

Any better?

[fostertom]

Can you say that again - don't get!

[wannabe]

Copy all the lines with this style onto a specific layer. When in paperspace, isolate the layer and copy them and use CHSPACE to copy one set to paperspace where you can use linetype scale differently?

 

EDIT: The PS and MS instances will need to be separate layers. The MS layers will need to be frozen in the viewports.

 

Probably best to disregard this idea and creat a new linetype using the express command to do so.

[fostertom]

So this is about how it displays and plots in paperspace, but still leaving display in modelspace crazy as described?

 

I do have all the Batting on one layer.

[fostertom]

creat a new linetype using the express command to do so.

 

How would that be different from Batting?

[wannabe]

You would basically have a copy in model and paperspace.

 

The entities in modelspace will be on a separate layer to the entities in paperspace, and the modelspace only entities would have their layer frozen in the viewport(s).

[wannabe]

How would that be different from Batting?

 

You wouldn't have variable widths....I don't think.

[fostertom]

OK, couple of things to try there, thanks v much for the conversation!

[wannabe]

Or you could copy another viewport over the top of exactly the same features. One viewport will have all items except the bating turned off and the other viewport will have the inverse layer settings.

 

Each viewport would have the opposite PSLTSCALE.

 

Think that sounds easier and more accurate overall.
