Undet palette View Sections tab

< Back

UNDET View Sections Tab allows to create, edit and manage View Sections, which you will need to investigate Point Cloud Objects and create project documentation from imported Point Cloud Data Files. Also, you can manage Coloring Settings to achieve better performance of Point Cloud Object and to enhance visibility of Point Cloud details.

There are three lists, which will help you to organize your further work with Point Cloud Objects:

  • View Sections List.
  • Data Files in Active View Section List. 
  • Logic Classes in Active View Section List.

View Section List shows and helps to manage all created View Sections.

Data Files in Active View Section List shows precisely those Point Cloud Data Files, which are only visible in Active View Section. In this List you can use the same manage tools as in Data Files tab’s List, where you can see and manage all imported in UNDET Project Point Cloud Data Files.

Logic Classes in Active View Section List shows precisely those created Logic Classes, which are only visible in Active View Section. In this List you can use the same manage tools as in Logic Classes tab’s List, where you can see and manage all created in UNDET Project Logic Classes.

Colored bar will be displayed next to the Data Files and Logic Classes in the Active View Section Lists showing points proportions in the Active View Section.

View Sections tab

Note: only Create panel will be active at first, other panels will be activated once there will be active view section created.

Create Panel

Create Panel
[Rectangle] – Creates View Cection by defining rectangle.
[Line] – Creates View Section by defining Line and View Section thickness.
You can create View Section by defining two points on the screen plane. The thickness of section is defined in Thickness (m) field, when you slide out Create panel by click on its title bar.
[Box] – Creates View Section by defining box.
The base of the Box is drawn parallel to the XY plane of the current UCS (work plane). The height of the Box is specified in the Z-axis direction. You can enter both positive and negative values for the height.
You can specify Box parameters by entering only two diagonal points of the Box. In this case it would be helpful to turn on Node Object Snap to bind Box diagonal points to PC Object’s points
[Point] – Creates box View Section by defining its middle point.
[In Viewsection] – Creates rectangular View Section in active View Section (extends are taken from the active View Section)
[Co-planar XZ] – Creates View Section co-planar to XZ plane of current UCS by defining point and View Section thickness.
You can create View Section by defining point on XZ plane of current UCS (work plane). The thickness of View Section is defined in Thickness (m) field, when you slide out Create panel by clicking on its title bar.
[Co-planar YZ] – Creates View Section co-planar to YZ plane of current UCS by defining point and View Section thickness.
You can create View Section by defining point on YZ plane of current UCS (work plane). The thickness of View Section is defined in Thickness (m) field, when you slide out Create panel by clicking on its title bar.
[Co-planar XY] – Creates View Section co-planar to XY plane of current UCS by defining point and View Section thickness.
You can create View Section by defining point on XY plane of current UCS (work plane). The thickness of View Section is defined in Thickness (m) field, when you slide out Create panel by clicking on its title bar.
[By Surface] – Creates View Section for statistical point cloud surface.
[By Line] – Creates View Cection by selected line.
[Duplicate] – Creates a copy of active View Section.
[Multiple ViewSection] – It will multiply your initial View Section through the AutoCAD’s 3D Array Rectangle.
[Multiple ViewSection through a path] – It will multiply your initial ViewSection through the AutoCAD’s 3D Array Path. For this you need to have a path (Line/Spline/Polyline).
Thickness(m) Define thickness of View Section, created by line or XY, XZ or YZ Co-planar, by entering value in meters.
Rectangle by USC– When checkbox is unmarked changes UCS before creating Rectangle View Section (works as it was developed initially).
– When checkbox is marked does not change UCS before creating Rectangle View Section.
Show surroundings– When checkbox is unmarked shows only points within View Section (works as it was developed initially).
– When checkbox is marked shows View Section points and surrounding of decimated point cloud (Decimated surrounding is shown only when the View Section visualizes all scanned points- green light bulb).
Precise point counting– When checkbox is unmarked calculates points in View Section approximately, therefore provides greater performance (works as it was developed initially).
– When checkbox is marked calculates points in View Section precisely, therefore performance is much lower but in this case calculation consider whether the scan positions and logical classes are turned on/off for visibility.

Edit Panel

Edit Panel
[Swith Grips] Changes grips orientation in Edit mode (when grips are turned on and View Section boundary is visible). When you select created View Section by clicking it on the drawing or selecting Edit button you can change section grips’ orientation. Switch Grips button toggles between object grips’ orientations and changes Base Edit Plane’s placement.
[Edit] – Turns on Active View Section grips and makes View Section boundary visible for editing.
[Clip Inside]Defines polygonal selection to Clip the points inside selection area.
– Selection O – Clip the Object by selecting only polylines.
– Selection P – Clip the Plane by selecting base point.
[Clip Outside] – Defines polygonal selection to Clip the points outside selection area.
– Selection O – Clip the Object by selecting only polylines
– Selection P – Clip the Plane by selecting base point.
[Undo] – Reverses last edit command. When you do some changes in View Section (move grips or launch Clip command) you can reverse these changes once.
Z (m)A dynamic field showing World height (WCS Z value) of your current View Section centroid. WCS Z value will change dynamically while using “O.Step” or changing parameters in ACAD properties. This field can be defined manually as well, in order to quickly move View Section to a required height.
O.Step (m)A field for Offset step value definition. Click on arrows next to it to step your current View Section up or down. Mark a checkbox next to step arrows if you want to enable dynamic tracking of the UCS while stepping the View Section.
Offset direction – UCS Z Axis– When checkbox is unmarked, offset step moves in Z direction which is
perpendicular to the View Section’s active grips plane.
– When checkbox is marked offset step moves in UCS Z axis direction.
Crop visibility options (Clip inside and Clip outside)– When colour button is – Crop feature simply clips Active View Section visible points and does not recalculate them (works as it was developed initially).
– When colour button is   – Crop feature does not recalculate anything and simply forces to show all scanned points within crop region. Be aware that if your View Section is very big or/and “Max. visible point count” is very high, you might experience AutoCAD lag. In most of the cases we recommend to use “Max. visible point count” value up to 8 million to avoid this.
– When colour button is  – Crop feature clips Active View Section points and recalculates those (Checks if there are less than defined in “Max. visible point count” and if less than shows all points, if more than works as red button).

Manage Panel

Manage Panel
[Deactivate] – Turns off Active View Section to see Point Cloud Object in Preview Mode.
[Activate] – Shows all created View Sections boundaries in the drawing for selecting one of them to be active. Use it in order to toggle between earlier created View Sections.
[Classify] – Moves Active View Section points to defined Logic Class. You can create new Logic Class or choose existing one from the launched dialog list.
[Remove] – Removes selected  View Section from View Section List.
[Remove all] – Removes View Sections with unchanged default names from Section List.

View Preferences panel

View Preferences panel
[Coloring] – Changes Point Cloud Object’s in Active View Section coloring settings of by Intensity, by Height (Z-value) or by Distance from Reference Plane coloring options through launched dialog box. More
[Plane] – Defines Plane by clicking on one of the View Section face. This is Reference Plane for coloring intervals assignment using by Distance from Reference Plane coloring option.
[Image] – Converts Active View Section to raster image co-planar to Screen Plane view. Launches Image Preview Dialog Box, where you can set grid cell size in square meters to define image precision and detail level. It is strongly recommended to use 2D B&W Mode for digitalization of raster images.
