Good morning, I am trying to create themes in the QGIS map window but it will only allow me to create one theme. I wish to have one theme for my drill hole collars (plan view) and another theme for my cross sections (Cross_Section). After I have created the first theme, the add new theme option is greyed out. Anyone else have this problem or has a solution?

You will be faster and more accurate if you recreate an approximation of the hexagonal grid and then retrace all polygons manually using those cells.

However, I have text in the symbols that I would like to rotate to face straight up no matter what angle the whole symbol is facing. So far the text object I?ve been working with has a matrix transformation applied to it.transformation=?matrix(a,b,c,d,e,f)? I tried applying a second transformation just for the rotation with no luck. transformation=?matrix(a,b,c,d,e,f)? transformation=?rotate(param(textangle))? I then tried adding a rotation to the existing transformation transformation=?matrix(a,b,c,d,e,f) rotate(param(textangle))? After this I tried just using the rotate tag, which is supposed to rotate each character in the text independently transformation=?matrix(a,b,c,d,e,f)? rotate=?param(textangle)? I haven?t had a ton of time to play with it beyond that but I?m wondering is this just a limitation in the way that QGIS renders the SVG? -------------- next part -------------- An HTML attachment was scrubbed...
