How can I set my Surfer post label plane to screen when overlaid on a 3D surface?

Labeling points in a post map overlaid on a 3D surface map using the screen as the label plane requires the use of a 3D wireframe map. A 3D wireframe map can display post map labels using the Screen plane (as pictured below), but the 3D surface map cannot.  What you can do is overlay the post map with a 3D wireframe map (not surface), and then position the wireframe overlay to be on top of the 3D surface map, and turn off the visibility of the wireframe. 


Label a post map with the screen orientation by overlaying it on an invisible 3D wireframe map instead of the 3D surface map.

To do this, please follow these steps:

  1. Click Home | New Map | 3D Surface | Surface, select your grid file, and click Open to create the desired 3D surface map.
  2. Click Home | New Map | 3D Surface | Wireframe. Choose the same grid file you used for the 3D surface map in step 1, and click Open.
  3. Add a post map to label the map containing the 3D Wireframe:
    1. In the Contents window, click the Map object containing the 3D Wireframe layer.
    2. Click Home | Add to Map | Layer | Post, select the data file containing x,y locations and the labels, and click Open.
  4. Position the maps:
    1. If necessary, in the Contents window, click and drag to order the maps so that the map containing the 3D Wireframe layer is above the map containing the 3D Surface layer.
    2. Press and hold CTRL on the keyboard, and click both Map objects to select them.
    3. In the Properties window, click the View tab. Click the Projection drop down menu, and choose the desired projection.
    4. Use the Layout | Arrange | Align | Center command to align the plots horizontally.
    5. Use the Layout | Arrange | Align | Middle command to align the plots vertically.
  5. In the Contents window, for the map with the 3D Wireframe layer in it, uncheck the boxes for the 3D Wireframe layer and each of the 5 axes.
  6. In the Contents window, click the Post layer to select it.
  7. In the Properties window, click the Labels tab.
  8. In the Label Set 1 section, click the Worksheet column drop down menu and select the column containing your desired labels.
  9. In the General section, click the drop down menu for Label plane, and choose Screen.
