I have 2 ideas to improve the generation of terrain profiles.
The location of the profile run through the point cloud is usually determined by the developer/contractor. It is rarely up to the surveyors to decide where to make the profile.
The first idea would be to indicate a line (e.g. in DXF) that has been previously imported into the program and generate the terrain profile relative to it. That is, next to the ‘Draw profile’ button, an option could be added to select ‘select polyline’.
The best option would be to indicate the road axis as a polyline and automatically generate further polylines perpendicular to the axis at a user-defined interval (every 25-50 metres).
If there is anything unclear with my ideas please ask, I will explain exactly what I mean.
Thanks for your comments! Yes, we’re moving the direction of what you suggest. To build on what Daniel posted, you can also (as of preview 1.44) drape a line in the profile view and simplify it to best fit your point cloud.
