How to merge existing ways with Potlatch?

Thomas Schröder-4
Hi,

I try to merge two existing ways with Potlatch, but it does not work.
I followed the documentation:
----cite-start---
To merge two ways into one:

    * Draw your way as normal.
    * When you move your mouse over another way, the points light up blue.
    * Shift-click the blue point at the start or end of the other way.
    * Or: if the ways are already drawn, select one, then hold Shift and click
the other.
----cite-end----

Selecting one and Shift click the other always results in the
error/message "The ways do not share a common point".

How do I create a "common point" or merge points?

Thomas

[Sorry, first post went to Thomas directly, seems the list doesn't set reply-to field to the talk-au list :( ]

Hi Thomas,
It works for me like this (it's hard to put in words, but here goes)...
* Have two separate ways, that you want to join into one way (not for a T-intersection or a crossing)

* Select an end node of way1 (selecting end nodes puts you in a mode to extend the way by further clicking)
* Hover the mouse over the end node of way2 where you want them to join (way2's nodes will show as bigger blue squares)
* Hold the Shift key while clicking on way2's end node
* Way2 now becomes part of Way1

I've
gotten the "The ways do not share a common point" message before, when
I had way1 selected (but not an end node), and shift clicked in between
2 nodes on way2. I was doing this to add more nodes to way2 to smooth
curves of a freeway, but you can only do this if way2 is selected, but
I had the other side of the freeway selected.

Hope that helps,
BlueMM

Hi.

Note that you can only merge ways that meet end-to-end.

e.g.

*----way1----*-----way2------*

can be merged to make

*-----way3---*------------------*

So you cannot merge something like this where way 2 joins in the middle of way 1.

*-----way2-----*

Hi Paul,

Thanks for the hint, now it is working for me too.
On some ways I had to shorten the way first (because both endpoints were on
top of each other) and then extend the end to the end point of the other way.
