I have problem using Orthogonal Digitizing button from CAD Tools plugin menu. It moves the first point of the polygon by holding ctrl key pressed and pressing right mouse button till the last angle is squared. Is it possible to change setting to move the last vertex till the last angle is squared?
Sergey, on QGIS 1.7.4-4 on Mac 10.7.3 with CAD Tools ver. 0.5.9, I am not seeing the first vertex being moved. In fact, I notice that the last vertex (one currently under the cursor?) is being moved, as per your request.
On examining the relevant Python script...
@ line #91, I notice the point-moving method as using the last vertex:
Note "# NO: move the last point!" comment, and that last line contains:
Maybe this is a newer version of CAD Tools than you are running? My version exhibits the behavior you are requesting. There does not seem to be an option -- short of editing the plugin's code -- to toggle which point gets moved.
You may want to request this feature on the CAD Tools issue tracker at QGIS.org or the one at code.google.com. Not sure which is the appropriate, since there is not one listed at the plugin's QGIS repository page.
