MX has the functionality to convert a 2d survey with annotated spot levels into a 3d Survey. The function is called 2D to 3D Surface, it use the text for the spot level values to generate a triangulations surface and adds levels to the original model.
The example below uses a 2D survey that has already been converted into an MX model (2d survey GENIO.TXT attached).
Load up the 2D to 3D Surface tool (MX>Modify>Edit Models>2D to 3D Surface). The first panel is where the model is selected and masking if required is applied. If you tick Apply Levels to Existing Strings the strings in the 2D models will be draped automatically onto the created triangulations model.
Click into the Point Shift panel. Generally the text for the level value is located away from the point that it relates to, for this model I need to shift the location to be 1.52m left and 0.135 down.
Click into the Data Filer panel. In this panel you can apply an minimum and maximum level range to exclude any rogue text values from the model.
When you have set up all the panels are required click Apply or OK to run the tool. The tool will run and create a triangulation model and apply levels to the original 2D Model as shown below.
