Set a Reference Point on a Line

Modified: 7 Jun 2026 Viewpoint Estimating Estimating Help

Setting a reference point enables you to mark an individual elevation point on the line for use when you set grid properties in the Grid tab or when using matchlines to work with multiple drawings.

You can view the reference points after setting them by clicking Layers on the toolbar and selecting Reference Points. When you create a reference point, Viewpoint Estimating automatically activates the layer on which the reference point was created.
