|---|---|
| Point + Point | Distance |
| Point + Line | Minimum distance |
| Point + Plane | Minimum distance |
| Line + Line (Parallel) | Distance |
| Line + Line (Not-Parallel) | Angle |
| Line + Plane (Parallel) | Distance |
| Line + Plane (Not-Parallel) | Angle |
| Plane + Plane (Parallel) | Distance |
| Plane + Plane (Not-Parallel) | Angle |
- The remaining parameters are set along with the project diagram - benchmark dimensions.
- Click on the drawing of the completion of the three-dimensional annotation, three-dimensional annotation was selected highlight, pop-up dialog box, you can enter Lines should be re-edited; Drag the mouse to change the position in the plane where the annotation is located.
Example: The following view is an activated view with a baseline size. The effect is as follows.
