Basic Tools

Tools in RealWorks can be classified into two categories: basic tools and highlevel tools. The basic tools can be used alone or be open inside a high-level tool to perform basic operations in the two following processing modes,

Registration * and OfficeSurvey / Modeling ** (or Production ), i.e., preparing data for high-level tools. In such cases, you cannot save the result. In general, the basic tools are represented by toolbars containing the operations arranged as icons or dialogs.

Note: (*) In the Registration , only the Measurement tool, Limit Box Extraction tool, Shift Project , Generate Key Plan from TZF Scans and Generate Key Plan from Current View are available.

Note: (**) The Modeling processing mode is not present in RealWorks ( Base ) and Advanced .

Measure Distances

This tool allows you to make point-to-point distance measurements, angular measurements, point-to-scanning position measurements, orientation measurements, etc. You can try as many measurements as you wish and for those you need later on, you can create them as persistent objects in the database. The created measurement objects will be put under the current active group. Measurements are based on pickings which can be free (or constrained).

Open the Tool

A measurement determines the distance two between picked points, calculates the angle from three picked points, shows the XYZ coordinates of a picked point and gives the orientation of a picked point on a sloping surface, etc. It is important to note that picking for the measurement will always function on objects, that is, either on points or on geometric shapes. You can still navigate in the 3D View while performing a measurement but you cannot select an object.

To Open the Tool:

1. Display an object (point cloud, mesh or geometry) in the 3D View .

2. From the Tools menu, select Measure . The Measurement and Picking

Parameters toolbars open.

In the OfficeSurvey / Modeling (or Production ) mode, if you use the tool in the

3D View , the toolbar looks as shown below:

If you use it in a 2D View , the toolbar looks as shown below:

In the Registration mode and if you use the tool as a main tool, the toolbar looks as shown below:

Basic Tools

The toolbar is composed of a set of icons. They are grouped by category: 1 -

Distance Measurements , 2 - Angular Measurements , 3 - Point Measurement , 4

- Orientation Measurements , 5 - Create and 6 - Close . The measurement type which comes first is the one selected during the last use of that tool. While you are in this tool, an information box will appear on the top right corner of the 3D

View , and the mouse's cursor will change its shape to that of a ruler. When you are on a 3D point, a circle surrounding this point appears at the end of the ruler.

Note: Each type of measurement can be activated via its corresponding icon in the Measurement toolbar or by selecting its related command from the pop-up menu.

Note: In the Ribbon , the Measure icon can be reached from the Cloud group, on the Edit tab.

Note: A multi-point-distance measurement, when resulting from a measurement done in the 3D, has no normal in its properties. The same measurement, when done in 2D (like the tank measurement or a polyline measurement drawn on a 3D locked view) has a normal in its properties.

Trimble RealWorks ® 10.2 User's Guide 532

Generate Key Plans

What is a Key Plan ?. From Trimble Scan Explorer 's point of view, it is purely a

2D view (of the whole project or of a station (or set of stations)) with a set of triangles superimposed. Each triangle symbolizes a station's position. From

RealWorks 's point of view, a Key Plan is a Preview and a set of split Orthoimages . All are put under a folder named Key Plan under the Images Tree . A

Key Plan is mainly computed within RealWorks * and loaded in Trimble Scan

Explorer . The computation can done either from a unique (or a set of) TZF scan(s) or from a point cloud displayed in the 3D View . For both methods, the user interaction is restricted to selecting the input. No parameters are required as they are automatically set.

One of the parameters is the Projection Plane , which is a plane on which points are projected. It is characterized by a projection direction (Normal ) and a

Position . The way this Projection Plane is set by default depends on the chosen method and on what is displayed in the 3D View or not. The Projection

Plane is a Top View when generating a Key Plan from TZF scans, and the focal plane when generating from the displayed point cloud.

Another parameter is an Area Of Interest which is used for computing a Key

Plan . By default, the size of the 3D View is considered as the Area of Interest .

It is up to you to size the 3D view to a dimension to compute a Key Plan to that size (only for the Generate Key Plan From Current View feature).

For the Generate Key Plan from TZF Scans feature, the option to render the computed Key Plan is based on the Elevation information. The Elevation value is calculated for each point based on its distance to the Projection Plane .

Points that are far away from the Projection Plane are rendered Red . Those that are closer are rendered Blue .

Basic Tools

For the Generate Key Plan From Current View feature, the option to render the computed Key Plan is not based on the Elevation information but on the Cloud

Rendering options ( White Color , Cloud Color , Station Color , Scan Color , Gray

Scaled Intensity , Color Coded Intensity , Color Coded Elevation and True

Color ). Points are rendered according to the chosen option.

533

The Preview is an Ortho-Image of low resolution which is about 0.1 megapixels. The Ortho-Image , which is split into a set of small pieces of Ortho-

Image , is of high resolution which cannot exceed 10 megapixels. Each split

Ortho-Image is named as follows ImageX_Line Index_Colum Index . It has a size (W x H) in pixels which is about 500 x 500 pixels.

From the 9.1 version of the software, a Key Plan has two new attributes which can be viewed when displaying its properties. These attributes are the

Elevation Max and the Elevation Min of the data (point cloud) along the Z-Axis of the current frame. When a Key Plan has been created with an earlier version of RealWorks , i.e. before 9.1, these attributes are not available. But when you load the Key Plan in RealWorks 9.1, they are automatically computed.


The attributes mentioned above are editable manually in the Property window.

This can be useful in case of a Key Plan with several floors because you are able to filter the positions of the stations to keep only those belonging to one level. The attributes of a Key Plan belong to the Key Plan , so that each is editable individually, and the result is visible directly in Trimble Scan Explorer

(if the Filter Station Markers by Elevation Range option has been checked).

These attributes, once changed and saved, become persistent. This means that you are not able to restore them to the default values.

Note:



(*) You should save your RealWorks project to be able to load the newly computed Key Plan in Trimble Scan Explorer .



A file with the RWV extension is created per Ortho-Image . All RWV format files are put under the RWI folder.

Tip: All Key Plans are created in the root of the Images Tree and have the same name: Key Plan . Only its order indicated between brackets allows differentiating one Key Plan from another Key Plan . To make this distinction clearer and more obvious, we advise you to manually rename all Key Plans (in the Name line of the Property window).

Tip: You can export an Ortho-image from a Key Plan or the Key Plan itself toward Trimble SketchUp . For more information, refer to the Export an Entity to

SketchUp

(on page 1528) topic.

Note: A Key Plan has no layer.

Basic Tools 535

Generate a key Plan from TZF Scans

This method uses the Top view (of the project) as Projection Plane regardless of what is displayed in the 3D View . Its Normal is parallel to the Z-Axis of the current frame of the project. Its Position is the Origin or barycenter of the

Projection Plan .

To Generate a Key Plan From TZF Scans:

1. Select either a project (1) or a station (2) or a TZF Scan (3) .

2. From the Tools menu, select Generate Key Plan From TZF Scans .

Note:

 When selecting a project with some TZF format files inside, it is not necessary to be within a specific processing mode.

 The Generate Key Plan From TZF Scans feature is dimmed when there is no TZF scan in the project.

 You can be in Isometric or Perspective as projection mode.

Note: (1) All TZF Scans (of the project) are used for computing Key Plan . (2) All

TZF Scans (of the station) are used for computing Key Plan . (3) Only that TZF

Scan is used for computing Key Plan .

Note: A filter is applied on the X , Y and Z directions when generating a Key

Plan from TZF Scans in order to remove parasite points.

Note: In the Ribbon , you can reach the Generate Key Plan From TZF Scans feature from the Key Plan list, in the Scan Explorer group, on the Home tab.


Generate a Key Plan from the Current

View

This method uses the current camera view as the Projection Plane.

Its Normal direction is perpendicular to the plane of the screen. Its Position is the Origin or barycenter of the Projection Plan .

To Generate a Key plan from the Current View:

1. Display a point cloud in the 3D View .

2. Rotate the scene to specify the point of view from which you want to create a Key Plan.

3. From the Tools menu, select Generate Key Plan From Current View .

Note: This feature is dimmed if there is no point cloud displayed in the 3D

View .

Caution: You need to display only clouds from a single project. Otherwise an error message appears.

If you are in the Perspective projection mode, a warning dialog opens and warns you that the project mode has to be changed to Isometric to be able to process to the Key Plan generation.

If you choice No , the process is then aborted. If you choose Yes , the projection mode changes then during the operation and takes back its state once finished.

Note: In the Ribbon , you can reach the Generate Key Plan From Current View feature from the Key Plan list, in the Scan Explorer group, on the Home tab.
