Hi, for my master thesis I use gxsm for such a while, thanks for such a nice and easy working program! Now I was wondering if there is any option like "thick line scan". What I'm looking for is the following: I need to measure the height of several steps. For having a good result I have to take the average of many measurements. It would be much easier, if the line would be broader, that means, would be a sum of many parallel lines. Such a function is also nice to watch a structure without the noise. Is there any function like this in GXSM?

There's also another question: Using Plane Sub my picture is wonderful flat. But if I do the line scan now, there are still just the two option of the rough data without any subtraction or a line regression. For example having a step, it is still not possible to have the areas next to the step flat. They still have a sloop like in the rough data or the line regression creates another slope due to the step. Did I miss the opportunity to use the subtraction of the PlaneSub for the line scan?

Thanks a lot for your help!
