Model by section needs improvement.

Recently an user from this forum suggested me the model by section tool. I tested, is very cool but has a pretty big limitation that makes the tool close to unusable.

This section tool in combination with the follow line tool would make an awesome tandem.

Been testing the cloud capabilities of Descartes and overall are great but found the line extraction to fail a bit too much when extracting alphalt limit lines on a mountain overpass.  The centerline extraction was a breeze because its very clean. So using the centerline as a path for the cross section tool and be able to advance n meters with the hit of a keyboard key would make the tool waaay much more usable. 

Actually you've to surf back with the cursor to the cross section panel and click to advance and the most cumbersome part is that you need to eyeball how much degrees you whant to turn the view.

Having the centerline as a path you could convert to spline by points first so that the tool can extract the tangent at each position and simply keep moving on at the hit of a key. As a helper, option for bringing the previously drawn section snaped to mouse curssor as a temporary block as when you attach a reference in interactive mode, would allow to have a draft you may initially place as bet fit and simply move needed vertex to fully fit.

I can submit the mobile scan data for testing purposes if you pople whant it. (with the breaklines I've extracted and such)
