How to Stake Out / Measure Surfaces 8.8

 General description:  A Digital Terrain Model (DTM) can be staked/measured for height values. The heights of the measured positions are compared with the heights of the Terrain Model at the same position. The height differences are displayed in the Information bar in a Cut/Fill format.

 Staking out/Measuring a Terrain Model can be used for:

•  Stakeout/layout where the Terrain Model represents the surface to be staked/laid out.

• Quality control purposes, where the Terrain Model represents the final project surface.  Given:
•  Instrument is connected and set up with known station and height.

• Terrain Model active within the current job. Refer to Importing data to the project step-by-step.

➜ The Cut & Fill procedure is the same as in the Stakeout/Layout applications, except the heights to be staked/laid out are taken from the selected Terrain Model.

➜ Note that main workflow refers to GNSS. For Total Station press Measure, then Store.

 Cut/Fill can be carried out in three ways:

• Manual Total Station

•  Robotic Total Station

• GNSS

If using a Manual Total Station, the Information bar is updated after each point is measured.

 If using a Total Station in Continuous Mode, or if using GNSS, real time measurement data is displayed automatically in the Information bar.

How to stake out/measure surfaces step-by-step

1.  Open the Cut & Fill app.   
   
2.  Tap the required Terrain Model.

   ---

   ➜ The Cut/Fill value is colour coded, depending on whether the height is above-grade, below-grade, or on-grade, when compared with the Terrain Model. Refer to Cut/Fill colour indicators for details.

3.  Record points by tapping Measure.

   ---

   

   ---

   ➜  Cut & Fill offers a Foreman View.

   ---

   
   

   ---

   ➜  To display Foreman View and Map View next to each other tap Multiview Config. ➜  The Cut/Fill tolerance level can be selected in Tolerances, which is found in Settings > Units & Tolerances.

 How to stake out/measure IFC objects step-by-step

➜  Scan and Adv. Surfaces licence needed.

1.  Open the Cut & Fill app.  

   ---

2.  Tap the IFC object to be staked out/measured.

   ---

   
   ➜  Select Foremost is active by default, so that in case multiple objects overlap each other, the object in the foreground is selected automatically. When disabled, a selection list is displayed and objects can be picked from the list. For detailed information on refer to: IFC object selection using Select Foremost

   ---

   
   ➜ IFC objects may consist of multiple faces. The Cut/Fill value is calculated based on the active face. In the Map view an additional toolbar button allows you to quickly toggle between the upper, lower, or any intermediate faces of an object. You can select multiple objects at once, and the active face remains consistent as you navigate the map. By default, the Cut/Fill value is calculated based on the top face.  

   ---

   
    ➜  In 3D mode as well as in the Cross Section view a vertical, dotted line graphically indicates to which face the calculated value refers.

   ---

   

   ---

   ➜ To activate the cross section view, select View  > Cross Section from the Map Handler.

   ---

3.  Record points by tapping Measure.  The colour of the stored point indicates whether the point is in or out of height tolerance. 
   ➜  To change the tolerance settings go to Settings > Units & Tolerances. 
   ➜ Cut & Fill offers a Foreman View.
   
   To activate the foreman view, select View  > Foreman from the Map Handler. For detailed information see: How to stake out/measure surfaces step-by-step

 Working with offsets

 An Offset can only be applied to the selected IFC object.

1.  From the Toolbox select Offset and enter an offset value.

   ---

   ➜  When an offset is applied, the Offset indicator is displayed in the top left corner of the map view. The indicator disappears when all possible offset values are set to zero. You can tap the Offset indicator to quickly access the toolbar.

   ---

   
   ➜ The defined offset value will automatically be applied to any other selected object. To reset the offset value, enter zero (using the keyboard).

 Available IFC tools 

➜ The following IFC specific tools are available from the Map Handler > View  button.

Tool	Description
	Object Info Displays the IFC attributes of a selected object.
	IFC Tree View  Displays the tree structure of an imported IFC file and allows for selecting objects within the tree structure and for hiding/showing objects in the map view. See also: Using IFC Tree View step-by-step
	Attribute Info Config Allows to assign up to ten IFC attributes of an object class to a value in the information bar. See also: Displaying IFC attributes in the information bar
	Isolate  Reduces the number of visible IFC objects by hiding single or several objects of a specific object class. This function correlates with the visibility settings of the IFC Tree View.  See also:  Isolating IFC objects in the map view  Hiding IFC objects in the map view
	Select Foremost Selects/Deselects the IFC object that is closest to the viewer. See also: IFC object selection using Select Foremost
	Edge Style  Allows to change the edge style of displayed objects. See also: Setting the IFC Edge Style step-by-step
