Pedit: some lines do,some lines dont!!

[theo_193]

Hi guys,

my question is that once i try to p-edit some lines,i actually want to join them,i have some arc's and some lines,to the most of them it worked,but on some it doesnt.When i press on them they dont appear dashed,like the others when it worked.I checked if there is a gap with the others.Any ideas why?

 

And something more,i then want to spot this polyline in every 40 m.How does it work?

 

Thank you very much..

What does your command line/text window say when you try to pedit>join them? (I'm guessing it says the they're on a locked layer, or they are non-coplanar.)

Could some of the lines have an elevation of something other than "0"?

Also check to see if the objects that aren't cooperating are closed polylines. If they are you can't join them. You'll need either to open or explode them first. If it simply won't let you select them at all, then you've either got objects on a locked layer or perhaps even x-ref'd in.

Thanks a lot guys.

Actually the problem is that the elevation was not 0,but when i change it into 0 from 100 for example,no problem.But when the elevation is -1500,then the line disappears!!Any ideas about that???

 

Thank you very much,you are very helpfull!!

I can't remember if it was here or on another site, but there's a lisp out there somewhere called "smash.lsp" It changes the "z" coordinates of all the objects in a drawing to zero. It won't tunnel into any blocks though. If you have blocks that have z coordinates that are not zero you'll have to explode them to use it. It's a very old bit of code, and may not recognize some of the newer entities but if you can find it, it might help you out.

Try using FLATTEN on the objects first. Then use PEDIT to join them. If they still aren't joining, there may be a small gap between the lines/arcs. If that is the case, set your gap tolerance to something other than zero.

Well, yeah, but anybody could do it that way:lol:. My way gives you all that pleasant time of searching the internet for an obscure lisp routine. Smash doesn't do any of the error checking that flatten does, it's just a brute force "change z to zero" routine.
