#Line Type Scale Problem
7 messages in this thread
HELP – I have a problem with line type scales.
I am revising drawing for a high rise office building consisting of two
towers, on a seven story base that covers a city block, and involves 83
floor plans, including the underground garage.
I am using a dashed line (LineType = Dashed) for various purposes. In most
of the drawings a LineType Scale of 1 gives the results that I want, and
can be scaled to the drawing scale using PaperSpace. I have a few drawings
that need a LineType Scale of 12 to give the same result; the line looks
and prints solid otherwise. All LineTypes are ByLayer.
I have printed out the System Variables of drawings of each condition, and
have found only minor differences such and the GridUnit or SnapUnit. I
have even changed these variables to match without getting the lines to
read correctly.
I have reloaded the LineType for the Dashed Line, and still can not get the
lines to read correctly. Maybe the LineType isn't reloading?
Does anyone have any suggestions.

Okay, guys, I'm NOT going to answer this one first so's you guys can all
criticize my answers again! Someone else holler "snipe!" awhile….

Snipe may be the problem.
I finally found out what my problem with LineType Scale was. The majority
of the drawing files had someones custom line type for dashed and only a
few had the actual Acad dashed line. The guy that started this project has
left many glitches in the file and I keep tripping over them.
I was continually trying to get the six files that had the Acad dashed line
type to act like the 72 that didn't. Every time I reloaded the line type
nothing was corrected. Now I am reloading the Acad dashed line type into
the 72 files using a script when I open the file.
The problem was bigger than I thought, but much simpler to solve, just
takes time.

Hey! I fixed a problem without trying! Now I'm 3 for 3!<g> Brian.
David:
I can't tell for sure where you are putting the lines… in paper space or
in model space… but, you can't have a linetype at two different scales in
a drawing. Also, the length of the line makes a difference as to whether
the line will appear dashed or not. This has to do with the way that
AutoCAD creates linetypes. You need to develop different linetypes for
different purposes at a uniform ltscale. We adopted the standard of using
ltscale and dimscale to 'tune' our drawings to the plotted scale a long
time ago and I have found this to be the best method available (thanks to
Autodesk and AEC). A set of custom linetypes must go along with this
scheme, however… especially if you mix different scales of drawings on
the same sheet.
See if you can get your hands on one of the AutoCAD books that deals with
customizing AutoCAD and check out what they say about linetypes. They are
pretty easy to create once you grasp the idea…

Can't get your linetypes to look Just Right? Does fiddling with LtScale to
make one look good screw up another? Is creating new linetypes for each
scale troublesome?
Don't you wish you there was an answer to your prayers?
Now there is! CHGSCA allows the AutoDude to specify linetype and new scale
factor for entities! Make your drawings more appealing! Win the favor of
your boss and coworkers!

David-
Are you xref'ing drawings in at different scales to these drawings? If so,
you will find that you'd need different LTSCALE settings for different
drawings.
