Undet project creator(Undet Indexer)

First to import a point cloud into SketchUp you need to create an Undet project with Undet Indexer.

Undet Indexer is standalone software to create an Undet project file from a wide range of scanners or scan data files. An Undet project database is created to handle massive point clouds and allow efficient management.

Supported formats *.E57, *.FLS, *.RCP, *.PTX,  *.ZFS,*.LAS, *.LAZ, *.PTS, *.DP, *.FPR, *.LSPROJ, *.FWS, *.CL3, *.CLR, *.RSP, ASCII / NEZ (X,Y,Z/i/RGB).

To open Undet Indexer in Undet Project Management block click [New]

The indexer window will appear before importing scan data, first you must select the project type based on your scan data set:

• LiDAR data management and analysis (The most common choice for large airborne LiDAR projects)
• Topography, corridor mapping, 3D city modeling (The most common choice for infrastructure projects)
• Buildings, Infrastructure objects, plants (The most common choice for terrestrial scanners)
• Detailed scanned objects (The most common choice for small detailed objects such as monuments, parts of buildings or areas with a footprint up to 100m2)

The Undet database has a double-file structure – Preview points and Full points. Selecting the right project type speeds up the indexing process, without losing full point cloud points and affects only the preview view. Preview points are created from all imported scan data by using GRID, its size depends on the selected project type. The default GRID size for each project is chosen for optimal indexing speed and faster preview navigation to find a place to load all points using the “clipping box”.

Undet loads all points in the “clipping box” when the point count is less than the maximum point count. The maximum point count can be set manually in the Undet Density toolbar according to your system hardware parameters. If your clipping box is too big to load all points you will only see the preview points.

Default “max point count” settings:

	LiDAR data management and analysis (The most common choice for large airborne LiDAR projects)   Preview points grid – 100 x 100 cm
	Topography, corridor mapping, 3D city modeling (The most common choice for infrastructure projects)   Preview points grid – 30 x 30 cm
	Buildings, Infrastructure objects, plants (The most common choice for terrestrial scanners)   Preview points grid – 3 x 3 cm
	Detailed scanned objects (The most common choice for small detailed objects such as monuments, parts of buildings or areas with a footprint up to 100m2)   Preview points grid – 1 x 1 cm

Note regarding Undet project creation:
Selecting the right project type speeds up the indexing process, without losing full point cloud points and affects only the preview view.

Undet project coordinate transformation settings

	Note: If you close an Undet project, the manually inserted coordinate transformation values will be lost. Please save them manually in a text file or take a screenshot of your transformation parameters.
	System name: Here you can choose different coordinate systems. You can change your project coordinate system at any time.
	Shift from start and rotation angles: You can manually insert these values to shift and rotate your project.
	Manually move point cloud.
	Manually rotate point cloud.
	Restore original coordinate values.

Undet project scan data management settings

In the Scan data management settings, a user can manage visibility and group scan data files into chunks.

In the Scan data management settings, a user can manage visibility and group scan data files into chunks.

Note: Use „Ctrl” and „Shift” for multiple selections from the scan list in order to group Data.

	Create group of selected scan data files.
	Remove created group (note: scan data inside group will not be deleted).
	Indicator showing the amount of individual scan data points in your clipping box.
	Check / uncheck to show / hide points from selected scan data file.
	Enable / disable selected scan station position center symbol.
