know that approach... Which is quite sad because I thought that displaying the Z scale for contours would be possible and I see it more correct/precise way to achieve the goal I'm looking for. Isn't it quite critical to display height scale just for contour lines, what do you think? It's one of the reasons contour lines even exist...that I can link the displayed Z values with corresponding contour lines?I've used the point cloud trick but still not satisfied neither with the results or workflow. That's why I'm currently using QGIS approach to display height values for these contours. Would be great if I didn't have to use it for this simple task because it would greatly simplify my current workflow if I could display Z values for contours straightly in CloudCompare.Another great think would be possibility to merge contour lines with the same Z value which is not possible either in CloudCompare, I think.Do you have plans to implement these features someday into CloudCompare? The program is otherwise great but I still miss these small features - especially the real Z value indicator for contour lines.
