Topic: Short polylines with broken linetype

Subject: Short polylines with broken linetype

I often work with linetypes which are non-continuous/broken, e.g.

--->--->--->--- used for a water pipe

---- - ---- - ---- - ---- for axis of a road

--- V --- V --- V --- for a fenceline
 

My problem is when i have a segment of a polyline with length less than 4m, the segment is not long enough to show the linetype. I could have a dodecagon shape (12 sides) with a fenced linetype as shown above, but if the fence segments are say 3.9m long each (total length of closed fence = 12x3.9 = 46.8m) the fence only shows as a continuous linestyle.

I don't know much about creating new/editing linetypes, so I was hoping there is a simple solution to this which lets me reduce this 4m segment constraint.

any ideas for a fix?

If applicable to AutoCAD 2011 : try to set the variable "PLINEGEN" to "1" ( if set on "0" ).
"0" generate polylines that begin and end with a line on each grip.
"1" generate polylines with a continuous design not depending on each grip.

PLINEGEN is/was already on 1

Sorry I had forgoten this :
Try to change individually the scale of the polyline in the properties pannel ( CTRL+1 ), you find it at the top :
GENERAL
Color
Layer
Line type
SCALE OF THE LINE TYPE : TRY "0.5" IF SET ON "1", TRY "1" IF SET ON "5"
etc......

I am aware of that idea, but that scales the size of the linetype too... so the V's or the >'s look half as big as they need to be.
 
I'm guessing the linetype code has to be edited? no idea how though

Edited I don't know but you can create your own line type.
 
There is an explanation in the PDF user guide that you should find in :
C\Program Files\AutoCAD 2011\Set up\ Docs with a name like :
acad_acg.pdf ( in the french release ) or :  acad_acr.pdf ( in english with a lot more pages ~34 MB ).
 
Find in the index at the end : Type of custom simple lines or equivalent ( sorry it' a translation from french ).
There is also a way to include forms and/or texts in the customised lines.
You create a XXXXXX.shx file detailing the sequence of dots, texts, forms etc....
I hav'nt tried to create one of mine so please let us know if and how you created our own line and also solved your problem.

Hello again, I have looked inside my PC and your standard lines on AutoCAD are in a file named acad.lin were you can look at the way to type a type of line.
If you create an other file with your lines you will have to comunicate with your coleagues + client for any exchange of file ( like any customisation with texts etc... )
