How do i extend lines to a specific point??? Help

[bgietzen]

My question is how do i extend lines to a specific point? I have attached a before and after image below for an example. But obviously it takes to long to do this line by line and getting the spacing correct. Is there a way to do this?

Mech 2005? Probably too old to have a Multileaders feature right?

[bgietzen]

just got AutoCAD 2012 LT - sorry I also just thought to change my profile.

[bgietzen]

These need to be lines only - not leaders. In 2005 CAD we had VGA and a program that we could select the lines and extend them (as shown) to a specific size other line (or in this case the connector shown).

With 2012 LT we cant use it.

You will have to do it manually in LT.

ok so is there a way to do it so my spacing is correct?

[SLW210]

I would find the point where they all meet, then polar array some plines after determining the angle needed, then fillet with radius=0. There are many ways, that is just one I would use (have used on similar).

 

You could also use, rotate with the copy option.

Ok is there a way to do it by some extend function. for instance i can do extend> fence and take those lines to a point. so is there a way to do it to a smaller area?

The AutoDesk website has this to say...

AutoCAD LT 2012

 

Use mutlileaders for efficient notes and callouts.

Can't you simply Divide the vertical line and then snap to the nodes?

LT's functionality is severely hobbled. There is no support for lisp or VBA, you pretty well have to use it straight out of the box. You can change menus and make your own buttons and stuff, but customization is limited.

 

My suggestion...make a block out of the lines you wish to draw. If you have a common number of conductors you use frequently, you could make a block for each. For instance one with 4 wires, another with 6, then 8..and so forth all the way up to however many you need. You can include any repetitive text and a generic text box when there is something you need to change per job. You could then put these on a tool pallet, and when needed, simply drag one off the pallet into your drawing. If you set the insertion point correctly, you could use the mid-point of the line that indicates the outside edge of the connector and drop it there, and they would always look the same, be spaced the same, etc. Then edit the text as needed.

[Jack_O'neill]

If LT does dynamic blocks, you could even go that way...have them all in one block, and simply select which one to display.

After you have the horizontal lines, copy all of them end to end so you have two lines on each row, joining end to end. Turn Ortho off, use the change command, select all the lines on the right hand side, pick the endpoint of the center line, or to any point you choose. They will now converge to a single point, stretch them or move your block, then trim them to the edge of the block. It is quicker to do it than it is to describe.

block example.dwgThis is what I had in mind:

 

The blue lines and text are a block, and you can see it's insertion point (the grip). If you have it bring it in exploded, then all you'd have to do is edit the text. You could do one of these for each type of cable you use, or put them all in a dynamic block, or group them up some way that would make sense to you.

 

Actual drawing file is attached if you want to play around with it.

What rkent said, the CHANGE command should do what you need

 

[bgietzen]

Not sure how to do that.

how do i divide the vertical line?

Then how do i snap

 

I am willing to do one line at a time but the problem with that is the time it takes the picture at the top of this thread shows the before and after. I manually had to draw each line from the horizontal lines with the #'s on it to the vertical line (connector) this example is one of the smaller sets I have to do.

[Jack_O'neill]

I haven't used LT in years, but try typing in "osnap". That should pop up a dialog box that will let you choose the ones you want to activate. The "divide" and "measure" commands will allow you to put nodes along the vertical line. Divide will let you choose how many spaces you want and give you equally spaced nodes, measure will let you say how far apart you want them.

[Jack_O'neill]

Unless you just want to though, using rkent's method makes dividing the vertical line unnecessary. It will take the endpoints of the horizontal line to the midpoint of that line in back, then you simply trim them off. They will be proportionally spaced with no other effort required.

EXACTLY - That is perfect. Thanks a million rkent.

never used "CHANGE" command before.

[bgietzen]

excuse me - thanks a million rkent AND everyone else that helped get to this answer. I have used this forum a couple of times and everyone here is A+ with getting me an answer to my question. Thanks again - I can honestly say - question answered!
