Snap‑to toolbar

The Snap‑to toolbar provides a simple way to select locations on objects in the map by snapping onto a specific point, even if no point exists. For example, you can use the Snap‑to toolbar to accurately select the end point of a line or the center of an arc from linework in a map file such as a BIM model or DXF file.

To display the toolbar, tap on the map toolbar and then select Snap‑to toolbar. The Snap‑to toolbar is only available when you are using General Survey.

To "snap" to a location on a feature, tap the appropriate tool in the Snap‑to toolbar and then select the item in the map. Depending on the Snap‑to tool you have selected you can select lines (including polylines), arcs, or a point.

To use the same tool multiple times, tap and hold the appropriate tool in the Snap‑to toolbar to keep the tool selection active and then select the features in the map. For example, to select the end points of multiple lines, tap and hold the Snap to end button and then select each line. To change to a different tool, tap a different button in the Snap‑to toolbar.

If a point does not already exist at the selected location, Trimble Access calculates a point. You can use calculated points like any other point, for example to stake out or to perform other Cogo functions. To be able to reuse a calculated point in the future, create a point from the calculated point and store it to the job.

Calculated points are automatically removed when you update the map, such as when changing map settings or linked files. To remove calculated points at any time, tap the Clear selection button on the toolbar, or double-tap in the map.

Snap-to tools

Select		Function
Snap to midpoint		Snap to the midpoint of the selected line or arc.
Snap to end		Snap to the nearest end point of the selected line.
Snap to intersection		Snap to the real or apparent intersection of two lines. An apparent intersection occurs when two lines do not physically intersect but could be extended to intersect at a projected point. To snap to an apparent intersection you must select two lines. A real intersection occurs at the position where two lines cross (in plan view). To snap to a real intersection you need only select one line close to the crossing point.
Snap to perpendicular		Snap to the perpendicular intersection of the selected point projected perpendicular to the selected line. The software creates a virtual point at the intersection of the selected point projected perpendicular to the line. If required, the line may be extended to determine the perpendicular intersection.
Snap to PI of arc		Snap to the point of intersection (PI) of the selected arc.
Snap to center		Snap to the center of the selected arc.
Snap to nearest		Snap to the nearest point of the selected line or arc.
Clear selection		Removes calculated points and lines and clears the selection of any other items in the map. Alternatively, double-tap anywhere in the map.

To create points from calculated points

1. Select the calculated point (or points) in the map.
2. Tap and hold in the map and select Create point. This option is not available if you have selected a mix of points and calculated points.

3. Enter the Point name.

4. If required, enter the code for the point in the Code field.

5. Tap Store.
