Use reference distance variables to add a distance between two points or a point and a plane. The reference distance changes as you move the objects it refers to. You can use reference distances in calculations, for example, to determine the spacing of rungs on a ladder. Reference distance variables automatically get the prefix D (distance), which is shown in the Variables dialog box.
This is the starting point for your measurement.
This will be the end point for your measurement. If you cannot highlight the correct plane, change the plane type on the Custom component editor toolbar.
Tekla Structures displays the distance.
The corresponding reference distance variable is shown in the Variables dialog box:
Note that the Add reference distance command remains active. You can click more planes if you want to measure other distances.
The distance changes accordingly. For example:
