Weird vertex on polyline

[douglas]

What is this vertex the pictures included with this post?  I haven't seen it before.  It started showing up when I was editing a co-worker's polylines. I am trying to reduce vertices, so I am snapping one onto another with osnap. Normally when I snap one vertex on another, they combine into one new square vertex.  Now I'm getting this slash thing, which doesn't have options for adding or removing the vertex.  How can I get rid of these or at least convert it into a normal editable vertex?  Thank you.

share that portion here as a DWG file please.

Since it started showing up when you were editing an existing polyline.....make sure you are in fact "combining" them instead of moving them to the same or very nearly the same position.  Check the current Vertex  count in the properties window compared to the number of grips you can count.

I highly recommend that you not do it that way.  They don't actually combine into one new vertex, but rather they pile up on each other, resulting in multiple vertices in the same place, and therefore having zero-length segments between them.  Coincident vertices like that can be the cause of various problems, one of them being your issue of not being able to add/remove a vertex when you hover over a multiple-vertex location.

Instead of grip-editing one vertex onto another, use the Remove Vertex option.  Or use PEDIT's Edit-Vertex option and the Straighten sub-option, which can get you around coincident-vertices conditions.  You can also use PEDIT / Edit-vertex / Move to separate coincident vertices from each other, so that you can Remove one with hover-over grip-editing.

@douglas ,

I have encountered this issue before and resolved by trimming or breaking a portion and then gripping one to another (or fillet) at the common point.

Thank you.  I understand.  It seems like good advice.  However, I never had an issue before.  Previously, the vertices seemed to combine without incident and there was never this different vertex indicating coincident vertices.  Perhaps that was an illusion, but it never caused problems before.  Is this symbol something new?

@douglas 

a more appropriate way to remove a vertex.......

Note: You can only remove one vertex at a time. Repeat operation as needed.

I'm not sure it's a symbol.  We can't tell from your image, but it may be just a row of grips too closely spaced to read separately.  Post a small drawing file with such an object in it.

You may be missing something if you're only looking in one plane, an issue that can be identified in minutes if it was not for your fear of sharing that portion of the DWG file 🙂

I've always used Kent1Cooper's method and recommend zooming in close before starting pedit so the × will be on a endpoint near to where you want to start straightening the polyline. You method doesn't actually remove any endpoints it simply puts them on top of each other which can create other complications later.
