Why can’t I join two lines even when they look connected?

Have you ever used PEDIT → JOIN, but CAD does not join the lines?

Sometimes the lines look connected, but there is a small gap between them. They can also have different Z values.

First, check the endpoints using OSNAP. If the lines have different Z values, FLATTEN can help bring them to the same level.

How many of you have faced this problem? What fixed it for you?

If you have an AutoCAD license, you get the toolsets like Map 3D free, you could use MAPCLEAN, which can fill gaps and also has a weed function and more.

 

What if they are overlapping and not a gap, you can get unexpected results from a large selection set and MPedit>Join from overlapping/collinear (P)Lines?

 

I use MPedit as well, you just have to run a polyline weed LISP (like PLDiet.lsp) sometimes to get single polylines.

 

You may also want to look into Overkill and Fillet with radius = 0, it can help with cleanup as well.

 

I know everyone that has this problem is working on a drawing that was not of their own and either generated by another CAD platform or by a past or former coworker. 

 

But, the best method for these issues are to properly use and setup your CAD not to have unjoined/unconnected/ends touching (P)Lines, Arcs, Splines, etc.

 

Good post from @irneb here on that issue...
