3 Transferring Files From SCC and CAD To PocketDTM

The following explores several options of transferring files to PocketDTM:

3.1 Transferring SCC Model To PocketDTM As Background Mapping

Prior to exporting model it is necessary:

• To transfer SCC library to PocketDTM (as outlined in Transferring SCC Feature Library to PocketDTM 14 ) to PocketDTM, to ensure that when the model is drawn within PocketDTM features are represented correctly

Within SCC, open Project and Model

Step 1: Export SCC Text File

From within the model, select 'FILE > Export Model > SCC Text File'

Select 'Ok' to export file to project folder

The file should be copied and pasted onto Storage Card

Step 2: Importing Background Mapping to PocketDTM

Begin a new job as outline in previous steps

Select feature library suitable for the data within 'FILE > General Options'

Go to the Plan View, select 'FILE > Import /Export > Import survey from SCC'

Select 'No' to Connect to SCC prompt (as file is already transferred to card)


19

Pick '16095.Model.sio' from the Open dialog and press 'Open'

The background map is imported into the Plan View

3.2 Transferring Client DXF to PocketDTM

There are a number of steps to importing a dxf to PocketDTM.

Step 1: Import DXF into SCC Two options are available when SCC is opened, either open an existing project or start a new project. When using SCC for the first time, it is necessary to start a new project.

Starting the Software

Double click the SCC Icon

On first entry to the software, or if there is no active projects, the following dialog will be shown on screen


20

Select 'Cancel'

From the Main Menu Bar within SCC, select ‘FILE >New Project’

Enter in a Project/Job name

Select a Project Template from the list / specific utility survey template

Select ‘OK’ The project template contains all the feature coding, layering, string labelling, modelling, symbology and annotation standards that will be applied to the project. The project itself consists of a spreadsheet containing the control stations used in the project, along with a feature library spreadsheet.

Importing DXF

Select 'FILE > Model > DWG / DXF File'

Using the Pick button select dxf


21

Select ‘Layer to Feature Mapping>>’ This option allows the user to map layer present in the dxf file with feature in the SCC Feature Library

Select 'Import layer map from DXF'

The table should be examined so that layers from the dxf are mapped to the correct feature code from the SCC library. Often layers which are not needed in the model are mapped to an IGNORE feature. This IGNORE feature would be set up in the users library to have a DTM status of Ignore and therefore not modelled.

Select ‘OK’ within the ‘DWG/DXF Input Layer to feature map’ Dialog

Select ‘OK’ within the ‘Import DWG/DXF file’ Dialog

Set the Plot Scale


22

Pick 'Create the Model and triangulation

Press 'Ok' to model attribute dialog

Save Model

Step 2: Export SCC Text File

From within the model, select 'FILE > Export Model > SCC Text File'

Select 'Ok' to export file to project folder

The file should be copied and pasted onto Storage Card

Step 3: Importing Background Mapping to PocketDTM

Begin a new job as outline in previous steps

Select feature library suitable for the data within 'FILE > General Options'

Go to the Plan View, select 'FILE > Import /Export > Import survey from SCC'

Select 'No' to Connect to SCC prompt (as file is already transferred to card)

Pick 'Sample.Model.sio' from the Open dialog and press 'Open'

The background map is imported into the Plan View

Generating Reports and CAD Drawing from Survey

SCC produces high quality reports from all SCC documents using the industry acclaimed Crystal reports engine. These reports can include data, charts, bitmaps and other rich content, and can be output to printers, PDF, Excel, HTML and Word files.

Sample reports are available within the SCC directory. These templates can be used to regenerate project specific report data directly from SCC. The Crystal reports also have the advantages that they allow the report layout to be readily changed without affecting the content, they allow automatic highlighting of out of spec values such that they can be easily picked up by anyone reading the report, and they can be readily exported to a range of formats including Word, PDF, Excel and HTML.

Note that while creation of new report formats requires a Crystal reports license, creation, viewing, printing and export of reports is included within the SCC license. To view a report, click 'FILE > Reports' and select sample report.
