I am having a puzzle about using mmqgis create vector layer option. I want to use UTM CSRThis are my options:

this are my options. I want a grid of 20,000 meters in the east and north axis. Nevertheless i have an error screen stating: "invalid width/height 6.0/6.0". As I understand my settings I should have 6 lines separated by 20,000 meters Am I understanding this in the wrong way? Thanks in advance

Without checking, I would interpret to options as follows:

  • left x: min x
  • width: width of the complete grid, therefore ... min x + width = max x
  • h spacing: width of one cell

same for the second dimension

I was getting this error too. The problem is is that the Width is less than the H Spacing you should just lower the H Spacing and the V Spacing will update automatically.

you can see the error in the source here:

search for Invalid width / height
