Join doesn't work but pedit Join does

[Anonymous]

Hi.

I am new to AutoCad and I don't understand why my polylines won't join.

Their ends are definitely touching in the same place and the Join command doesn't work. This is the first time it doesn't work for me. So I looked around the forum a bit and found the pedit command. Using the pedit join works and I don't understand why join in itself doesn't work. 

Thanks,

Nico

Normally when a command fails you get an error message at the command line? What was it, do you have the command line visible (or F2)?

Command: J
JOIN 2 found
0 objects joined, 1 object discarded from the operation

Thanks for the quick reply,

[steven-g]

Can you post the dwg with just those 2 objects is all we need.

Here you go.

Odd indeed. Join does work if you either select only one line to start with (and the second when prompted).

Ok, very interesting. Thanks, that will help. This is probably a bug with autocad itself right?

I doubt it, but you never know, if I create two new polylines tracing over yours then those behave? but I can't see in the properties any difference.

Your geometry is a long way from the origin 0,0 which can cause some problems.

[steven-g]

Your 2 polylines have a different elevation (Z height) if you increase the unit precision to 8 decimal places then the very last digit shows up the difference. This combined with the distance from 0,0 is probably the cause of the problem

I thought this was a 2d workspace how can something have a z coordinate?

[steven-g]

LT still has all 3 axis. Z doesn't alter all by itself but if you have geometry brought in from full AutoCAD then osnaps and geometry can affect what you do in LT. In this case it was an actual 'elevation' value. You would need to look at the drawing history to see why that is, we can't see that from just a drawing.

Do you get drawings from other people? or use blocks from a web site?

I received the drawing from a client, they might have worked with AutoCad 3D. That makes sense. But I still don't understand why Pedit Join works but just Join only works if you don't select multiple lines at once.

[steven-g]

Unfortunately neither do I, possibly due to some level of precision within the internal programming but that would just be a guess. You might want to try posting in the feedback section, but at least now you know where to look in the future if you have similar problems.

Yes, thank you very much.

I am having the same problem here! Then, how can we set the z coordinate at the same level? Is there any shortcut command for that?

@a_wanY4JUJ open up the Properties menu (CTRL+1) and change the Z value there
