There's some Cyber Monday gremlins we're experiencing at the moment. Things will return to normal shortly.

Hello, I'm having problems with the toposhaper extension tool.
I'm running it on a very simple topography and it keeps crashing.

I'm probably not using it well, I don't know... The tool 'from contours' seems to work perfectly but it's not as precise as toposhaper.

It looks like you run TopoShaper from the inside of the Group or Component. Could you instead just seelct the Group / Component.
