An xref inserted into a drawing inherits the ltscale of the host drawing
that it is xrefed into. For example if I have a drawing with an ltscale of
24 and I xref that into a drawing with an ltscale of 1, the xref uses
ltscale of 1 to display the objects. Is there anyway for xrefs to display
using their own individual scale instead of inheriting the host scale?? It's
not VISRETAIN or PSLTSCALE as I already tried that.


Thanks,

Ryan Small

Set up the Ltscale according to your external reference. Then use CELTSCALE
to set up new scale for new lines.

Type: Real
Saved in: Drawing
Initial value: 1.0000
Sets the current object linetype scaling factor. This sets the linetype
scaling for new objects relative to the LTSCALE setting. A line created with
CELTSCALE=2 in a drawing with LTSCALE set to 0.5 would appear the same as a
line created with CELTSCALE=1 in a drawing with LTSCALE=1.

Good luck.

Try a DDMODIFY on the xref, and change ITS ltscale?

The fundamental scaling in AutoCAD's linetype definition files has changed
between releases. It often helps to re-load your linetypes from a common
.LIN file. If your xref is R14 linetypes and you drawing has Acad2000
linetypes then you are off to a bad start. After years of wondering I have
come to the conclusion that I have no idea how linetype scales work so I use
a magic number system. For R14 the magic number for me was 10. In paperpace
I always set PSLTSCALE to 1 & LTSCALE to 10. In model space I set PSLTSCALE
to 0 & LTSCALE to 10 x scale I intend to plot out at.... so for 1:50 scale
plot I set to 0 & 500.

My magic number for Acad2000 is 0.2 but this may not be true for all
releases of 2000 as I found out when working on a newer release. Generally I
change all individual LTSCALES to 1 for all entities in the drawing. If I
need different linetype I create a new one using the express tool 'create
linetype' rather than fudge the individual scales on existing linetypes.

I even went to the trouble of writing two lisp routines to set the PSLTSCALE
and LTSCALE automatically when changing tilemode and used modemacro to
diplay the two scales in the status bar.

Hope this helps.
