intersection wire

[sachin]

hello

 

can any one tell me how to draw the intersection wire like a half circle passing over the other wire.

if you are using electrical it is in the Drawing Properties tool under Styles.

 

If not, you have to do it by hand or get a LISP written.

If you need a lisp, I have two.

hello dbroada

yes i m using 2008 electrical autocad.

i manage to get styles but it showing me text, dimension, table and multileader style.

May be i am wrong. can u tell me how do u go to styles and then draw the intersection wire.

i tried to draw by hand but its not perfect.

 

Regards

actually i dont have any idea about lisp.

what is that and how can it be usefull.

[ReMark]

Your terminology is incorrect. It is not referred to as an intersection wire in AutoCAD Electrical. It is called a wire gap (i.e. - where one wire crosses over another). The gap is usually created automatically. It can be set manually as well.

 

Using the Ribbon: Schematic > Insert Wires/Wire Numbers > Wire > Gap.

[ReMark]

Lisp is a programming language. Lisp routines are small programs that run inside AutoCAD. There are custom lisp programs that can be used to create the semi-circle that is used to denote one line crossing over the other. A good routine will insert the circle and trim away any unnecessary linework with some input from the user.

sorry for so many silly question, but i m new at autocad

no i m not using ribbon. how can it be usefull and how do i get it?

[ReMark]

OK, I thought the Ribbon was available in Electrical 2008. Guess I was mistaken.

 

From the command line type AEWIREGAP. Tell me if that works.

 

BTW...it is the crossing wire that receives the semi-circle (wire gap).

[sachin]

NO, When i type AEWIREGAP, screen says press F1 for help. Also in help i am not able to get the answer.

If you have it built into Electrical, I'd use that

 

Otherwise, here's a lisp from LeeMac (one of the best) post#18 http://www.cadtutor.net/forum/showthread.php?45820-Need-Lisp-Modified&p=313262&viewfull=1#post313262

 

Here's how to use a lisp http://lee-mac.com/runlisp.html

 

Here's what this one does

I will post a screenshot tomorrow (if I remember) to show how it is set. We NEVER draw crossings that way and only show intersections (with a blob).

[ReMark]

I agree re: intersections. They should be shown as a filled in black circle (in plain AutoCAD the DONUT command could be used).

 

However, when one wire crosses another in a drawing it should be shown using the half-circle (semi-circle). At least that's the way I was taught and it is the way it is shown in the book AutoCAD Electrical 2010 for Electrical Control Designers.

[ReMark]

NO, When i type AEWIREGAP, screen says press F1 for help. Also in help i am not able to get the answer.

 

Maybe the feature was added in a later release. In which case you'll have to either do it manually or use a lisp routine.

[dbroada]

to set the loop type crossing open your drawing and select drawing properties from the electrical wires palette. Alternatively the WD_DWG_CONFIG should get you to the same place. Under the style tab you have the option of crosssing, break & loop.

 

 

Once set, any new wires will have the loops added. To go back to a crossing type you can select the wire and right click to get the remove breaks option. I can't remember the corrct way to add loops to an existing wire but if you scoot the wire the loops will be added.

 

ReMark, loops are only a suggestion in BS and we have some project managers who like to see them - until they realise just how much extra we charge for modifying the drawings at which point they are usually happy with crossings.

remembered WIREs get loops, not LINEs.

Dave: Thanks for the image and the explanation.

[sachin]

hello guys.

 

Sorry abt the wrong information. I tried lot as you said but then i chek my autocad. Its normal 2008. Its not electrical.

i m still doing by circle and trim it off unnecessary part. i want to do it like your way its much easy and simple.

[dbroada]

if you dan't have ACADE then you will have to refer to nestly's post.

I know we have moved on but for the sake of completness following on from ReMark's post #6. In 2008 electrical (prior to the ribbon) the wire gaps can be added from the WIRE palette under wire miscellaneous.
