HiIm using AutoCAD 2007 LT.



I need to draw a beam, usually I draw the lines I need, and then, I offsetting
it twice, so I get 3 parallel lines.



Is there any command I can use in order to automate this? I mean maybe I
can draw one line and AutoCAD will follow with 2 parallel and offseted lines?



hope I didn’t push to far

 

Thanks

Shay

AutoCAD LT?  Well that rules out the use of lisp.  That leaves either a macro or Diesel.
 
Are you drawing a cross-section of the beam?

i have a co-worker with 2008 full, we can switch our computers. so assuming that i have 2008 full, how can it be done?thanksShay

There are some lisp routines and maybe even a couple of Dynamic Blocks floating around that can handle the task.  Metric or Imperial units?
We are talking a cross-section of a beam right?

 [/QUOTE]i need it metric.ive posted a picture of  what i mean.thanksShay

Did someone turn out the lights?  I see no picture.
It was a simple question that I've asked twice now.  I guess I'll assume you are drawing beam sections typically shown in most structural steel manuals.  It makes the most sense.

Our IT department blocks sites like that because they are potential virus threats.  Can't you just post the image here?

Are you showing a plan view with continuous lines for the outside edge of the flange and two dashed lines for the web?John Connor2011-03-15 15:03:10

i didnt notice there is attchment file here. thats way i looked for image hosting. in the formatting controls, i press "insert image" with the same image hosting url, is that ok?

Sorry...nothing appears in your last post that I can see.  Try reading this:
http://www.cadforum.cz/forum_en/forum_posts.asp?TID=5421&PID=13802#13802

i dont have the "Browse" button. any idea? i have flash installed

I have no more ideas.  Send a postcard.  LOL
 
I've described two ways to show a beam and neither are what you are looking for?  Then forget my previous suggestions as I don't think anyone has gone through the trouble to do what you are requesting.  Until I see an image posted here at the CADforum I think I'll have to stop.
 
Are you drawing a beam in elevation view?  If so, front side or right/left side? 
 
Somehow, some way, you should be able to describe, in words, what view of a beam you are drawing.  How tough can it be?  Pick a number:  The beam shown below is a W250x200x49.1

Looks like we have a winner folks.  It's number 3!  Yeah!1 - Top view.2.- Front view.3.- Side view.Try the suggestions Cad64 provided and let us know if that works for you.

thank you folks! its worked for us...no need to switch pc 

another small thing, i want all lines i draw using the "dline" command  to be joined. is theer a way to pre-command it? (i mean before creation)

Have you checked your Autocad Help files?In full Autocad there is MLINE, MLSTYLE and MLEDIT, so maybe there are similar commands in Autocad LT for DLINE? I don't know?

You're talking about "Caps" I believe.  What I mean by that is the open ends of your dlines are capped (closed) off.  This feature can be turned On/Off at the command line.
 
For those of you using full AutoCAD who fondly remember DLine from your LT days and wish you had it now, the South Plains AutoCAD Users Group has a tweaked version of the routine in AutoLISP form at their website free for the downloading.  It is aptly named DLINE.LSP and can be accessed via the link below.
 
DLine options include: Break, Caps, Close, Dragline, Snap, Undo and Width.
