Workflow Wizard Dialog

Overview

  • The Point Loading And Meshing workflow wizard dialog was implemented using the scripting sub-system of SEQUOIA.
  • It can be used to
    • Help new and existing users perform the typical steps of loading, converting, filering and meshing one or more point files.
    • Teach new users the basics of SEQUOIA.
    • Show to users interested in the scripting capabilities of SEQUOIA how custom dialogs can be implemented.

Dialog Layout

  • The dialog’s layout consists of 4 major areas:
    • The list of workflow steps is located at the left side of the dialog - they will be highlighted as the user steps through the process.
    • The upper right side of the dialog will contain the UI controls to perform the current step. These controls will change from step to step.
    • The central right area of the dialog will contain an About This Step description.
    • The bottom right area of the dialog will contain the buttons to control and navigate the wizard: [Previous], [Next], [Cancel] and [Finish].

The Workflow Wizard Steps

Step 1 - Select Point Files To Load

  • In the first step, the Controls area will display a list view to be populated with the Point Files to load.
  • The [Add] button can be pressed at any time to add to the list one or more Point Files in any supported format.
  • The [Remove] button will be enabled when at least one file is highlighted on the list. Pressing it will remove the file from the list.
  • The [Next] button in the bottom area of the dialog will be disabled until at least one file is added to the list.
  • Pressing the [Cancel] button will close the wizard dialog without performing any operations.

Step 2 - Convert Point Files To SPRT Format

  • In this step, the Controls area will display a button and a text field.
  • The button can be pressed to open a path selector dialog to specify the folder where the converted files should be saved.
  • The text field will show the path and will default to the path of the first Point File selected in the previous step.
  • If all Point Files selected in the first step are already in SPRT file format and no conversion will be required, both controls will be disabled:

  • You can press the [Previous] button at any time to return to Step 1 and change the list of Point Files to load.
  • Pressing the [Next] button will perform the file conversions, if necessary.
  • Pressing the [Cancel] button will close the wizard dialog without performing any operations.

Step 3 - Define A Region Of Interest

  • In this step, the Controls area will contain only one checkbox.
    • When checked (default), an additional Point Region Of Interest object will be inserted between the Point Loader(s) and the Mesher.
    • When unchecked, the Point Loader(s) will be connected directly to the Mesher object.
  • The [Previous] button will be disabled because the previous two steps have already been processed and no changes are possible at this point.
  • Pressing the [Next] button will create the Point Region Of Interest object if the checkbox was checked.
  • Pressing the [Cancel] button will close the wizard dialog, but any non-SPRT Point Files will be converted and stored at the path specified in Step 2, and Point Loaders will be created in the Document.

Step 4 - Create A Mesh From The Point Data

  • In this step, the Controls area will contain only one checkbox.
    • When checked (default), a Mesher object will be created from the Point Loaders.
    • When unchecked, no Mesher will be created, leaving the user with just the Point Loaders and optionally a common Point Region Of Interest object connected to them.
  • Pressing the [Next] button will create the Mesher object if the checkbox is checked.
  • Pressing the [Cancel] button will close the wizard dialog. The result will be the same regardless of the checkbox’ status, as no Mesher will be created, equivalent to unchecking the checkbox and pressing [Next] to finish.

Step 5 - Finish

  • In this step, the Controls area will contain only a text explaining that the wizard is completed.
  • Pressing the [Finish] button will close the dialog.
