Diversion Drain linetype


Recommended Posts

Good morning all,

 

I am trying to create a linetype that uses a polyline/block to create a series of thicker arrows.

 

I have written:

 

*DIVERSION,DIVERSION DRAIN ----->  ----->

A,.982117,-.256835,[DIVERSION,DIVERSION.SHX,X=0,S=.25].977201

 

But it does not seem to work just comes out as a series of dashes.

 

I have attached a few things that may help.

 

Cheers

Allison

Good morning all,

This linetype is using a shape, and if you draw a polyline, then the shape will stay the same thickness whilst the polyline is made thicker (see second picture below).

 

Your first problem is that the linetype definition file is not the same as the definition you quoted.

Your DIVERSION.LIN is:

*DIVERSION,Dirversion ----->  ----->
A,.004916,-.256835,.982118
There is no shape in it, and it would draw as a series of dashes (picture one below).

 

If you had the linetype file as you wanted

*DIVERSION,DIVERSION DRAIN ----->  ----->
A,.982117,-.256835,[DIVERSION,DIVERSION.SHX,X=0,S=.25],.977201
Note that there is a comma after the close square bracket, then that plots as picture 2 below.

 

The DIVERSION shape is about 14.7 units long, so the shape in the linetype is 3.7 units long. The shape overlaps itself because of your spacing. So you have not achieved your objective.

 

You should also note that with curved lines, the shape stays as an entity and does not curve with the arc.

Maybe experiment with the > text symbol.

 

*SUBSOIL_DRAIN_RIGHT,Subsoil drain right ---->---->---->---->---->---->--
A,40,-5.08,[">",STANDARD,S=1.8,R=0.0,X=-1.8,Y=-.9],-3

Whenever possible using the shapes installed with AutoCAD eliminates the need to keep track of them.

*Arrow,Arrow ->  ->  ->  ->  ->  ->
S,.0001,-.5,1,[TRACK1,ltypeshp,r=80,s=.2,x=0,y=.035],-0.0,[TRACK1,ltypeshp,r=-80,s=.2,x=0,y=-.035],.2,-3,.0001
