Add slice dialog

< Back

The Undet software generates raster images in the selected Revit view (floor plans, elevations, sections….)

Raster images can be generated according to Revit cut plane location and direction.

Add slice dialog top section

Undet slice menu functions:

|Undet project management section| Set project – open Undet project file (*.IPCP)
Open Undet Indexer – opens Undet Indexer (project creator)
Close project – close active Undet project
Scan positions – point clouds / scans data files manager
|Raster image management section| Sort images – sort generated raster images according to their size, larger images are sent to the background, smaller ones are brought to the forefront.
Hide selected images – hides selected raster image
Show all images – show all created raster images
Raster manager – opens raster manager dialog
Load 3D – converts Undet project file into an RCP file and loads 3D point clouds*
|Undet browser| WS (view sync) – Locates Undet Browser view by picking a point in the raster image

* First time convert Undet project file into RCS file is a time-consuming process, which can last up to a couple hours depending on the initial Undet project file.

Scan positions dialog

Raster images from point clouds are generated from enabled scan data that can be grouped and their visibility managed in the Scan data dialog.

Selected scan data files can be grouped into groups by clicking the right mouse button or selecting “Add” icon from the dialog menu.

Scan file visibility can be controlled for each file or group.

For example, to create a clear building elevation raster image you need to disable inside scans.

Raster manager dialog

All generated raster images in the selected Revit view can be managed in Raster manager.

Generated raster image visibility can be controlled for each file.

Revit section (for example floor plan – level1) can be combined with multiple raster images.

When “Track selection” is turned on, the selected raster image location can be tracked and identified.

Add slice dialog function and control

|Raster image generation settings| Point cloud slice (cut plane) reference elevation
Manually edit point cloud slice (cut plane) thickness from which raster image is generated
Set point cloud slice (cut plane) offset from Revit section view reference
Reads and updates raster image generation settings for Floor view by initial Revit section view range parameters (these parameters should be manually set during Revit project preparation)
Reads and updates raster image generation settings for the center (cut plane) view by initial Revit section view range parameters (these parameters should be manually set during Revit project preparation)
Reads and updates raster image generation settings for the Ceiling view by initial Revit section view range parameters (these parameters should be manually set during Revit project preparation)
Raster images can be generated outside of the Revit view range according to cut plane location and direction (see example below)

In floor plan view raster images can be generated choosing: Center view (cut plane line), Floor view, Ceiling view

In section or elevation raster images can be generated choosing: Center view (cut plane line), Forward view, Backward view

Sets resolution in millimeters to generate raster image

(see example below)

Generates raster image from the first visible points according to view direction and location (see example below)
|Coloring settings| Raster image coloring settings selection

(see example below)

A different coloring pallet can be used to get clearest view (see example in pages 22-23 below)
Pallet coloring intervals count adjustments
Coloring Interval size manual adjustment when Coloring by plane is selected
|Decimating and transparency|

Generates raster images from decimated points clouds mostly in cases where you need to preview a raster image faster or track changes in settings faster (see example below)

Decimated point cloud density increases from left to right

Makes “white” raster image pixel transparent (see example below)

Recommended to use only with sections or center “cut plane”

|Action buttons| Generates preview raster image for the entire project
Generates rectangular shaped raster image in the defined area (see example below)
Generates screen size / area raster image (see example below)
Updates selected raster image with new parameters
Option where to display raster image on the model (foreground and background)

Add slice dialog settings examples

Action buttons (Screen and Defined area) operational examples

Raster image generation region can be selected according to two choices:

“Screen Area” by window extents

Screen Area raster generation extends to the area marked in RED
Generated raster image zoomed out marked in RED

“Defined Area” by rectangle

Defined Area marked in RED
Created raster images by defined area marked in RED

Raster image resolution examples

Raster images can be generated with different resolution settings. Resolution selection is a trade-off between speed and a clear view. To understand objects, we recommend using a 20mm resolution, a more detailed resolution should chosen according to object size and needs.

Description generated with high confidence
1 mm 5 mm 10 mm 20 mm
20 mm 10 mm
5 mm 1 mm

Raster image coloring settings examples

Floor plan raster image colored by Intensity Floor plan raster image colored by Plane
Elevation raster colored by RGB Elevation raster colored by plane
Elevation raster colored by Intensity

View direction settings example

Raster images can be generated according to Revit cut plane location and direction:

In floor plan view raster images can be generated by choosing: Center view (cut plane line), Floor view or Ceiling view.

In section or elevation raster images can be generated by choosing: Center view (cut plane line), Forward view or Backward view.

Generated raster images from decimated point clouds examples

Generated raster images from decimated point clouds are mostly suitable for preview:

Raster image (5mm resolution) with enabled “Decimate” function |Low density|
Raster image (5mm resolution) with enabled “Decimate” function |Maximum density|
Raster image (5mm resolution) with disabled “Decimate” function generated from all points

Raster images transparency function examples

Raster images created with the transparency option are much heavier and require more time to zoom in / out, we recommend to use this option only when needed in specific situations.

Floor plan raster image Center Cut Plane raster image
Floor plan raster image combined with center Cut Plane raster image. Cut plane raster updated with “Transparent” option

Raster image example with enabled calculate distance function

The “Calculate distance” function generates a raster image from the first visible points according to view direction and location. This function is a trade-off between speed and a clear view. To generate such raster images takes more time than standard raster images.

For example, to get a clear view of a table we need to create a raster from the first visible points and eliminate points under table.
