[Qgis-user] clip still not working on osm shape

[Nicolas Cadieux]

Hi,
To modify the shape files, you need to activate the toolbars by right clicking next to a toolbar.  You will find a number of plugins also to help modify object.  

When you save a file, I think you have a input CRS and a output CRS.  Make sure the add both.  If it's not there, look in the processing toolbar for Qgis reprojection tools.  What version of Qgis are you working with?

I tried the same in ArcMap and there I got the same result. Then I tried a function in the toolbox under Data Management > Projections and Transformations > Project where you can choose the CRS and also the transformation algorithm. Then the shape of the town was shown in the right spot. I wonder if there is such a tool in QGIS.

I have only worked one day with 2.16 but it was long enough to see that it needed a complete removal of all previous versions as the menu had a mixe of the old and the new version.  After that, vector tools disappeared from the vector menu and reappeared in the new processing menu.  I had read about this in a French blog so I was expecting it.  Could this be the cause of your problem?
