I draw rectangles with the Shape Digitizing Toolbar. In QGIS 3 there is a Snapping Toolbar which provides a snapping function. But unfortunately it is not possible to use both together. So whenever I want to draw a rectangle I can not snap it onto a line which leads to incorrect results.

Here is the same problem but it occured in QGIS 2.

Any solutions for QGIS 3?

I am not sure how you setup the settings in the snapping tool, but here is mine

enter image description here

  • Enable snapping (red magnet icon)
  • Snap to all layers, but you can select active layer
  • Vertex and segment
  • 10 pixels

Because I have the above settings, I can snap polygons together even to the one I have just created:

  • The problem is using the snapping tool TOGEHTER with the shape digitilizing tool ( tool to draw rectangles).
