 Generate points orthogonal to a reference line. 
  
  
 | 
| • | Negative values place the orthogonal point to the left of the reference line. |  
 | • | The new point object is placed in the currently editable layer. |  
  | 
 
 
 
  
| 1. | Select the Orthogonal Points function and digitize the start and end of the virtual reference line (for a better illustration the virtual reference line ist red colored in the screenshot). |  
 | 2. | Then enter the position (based on the reference line) of the orthogonal point. |  
 | 3. | Change the symbol style by clicking the Symbol Style button before setting the orthogonal point. |
