POINTCLOUDPROJECTSECTION command

Automatically generates a 2D raster image with optional contour lines from a defined section box.

Method

The Project Section command context panel is automatically displayed when running the command.

Make a section selection, decide whether to generate lines alongside the raster image, set the parameters, and then click the Generate option.

Note: The options within the command context panel reflect those within the Command line.

Options within the command context panel

  1. Section selection
  2. Ortho image
  3. Line detection
  4. Output options
Section selection
Allows you to select BIM sections of any state to project.
Select section(s)
Click the Select arrow () and pick a section in the drawing.
Select all sections
All sections in the drawing are automatically selected.
Ortho image
Generate
Becomes available once a section is selected. Generates a 2D raster image from a point cloud section.
Pixel size
Controls the pixel size of the generated image.
Resolution
Determines the resolution of the projection. Allows you to switch between Finest and Adaptive.
Finest
Produces a sharp and detailed background picture. It uses all the points in the point cloud.
Note: The projection in the finest resolution would take longer to complete.
Adaptive
Produces a less detailed and softer background image.
Overwrite projection images on regeneration
If checked, overwrites any old image files on disk related to the section.
Line detection
If On, automatically creates lines or 2D polylines along the intersection of the point cloud with the section plane.

Allows you to modify the parameters that control the 2D line generation with a live preview.

Gap tolerance
Controls the search area for the algorithm to draw lines. Gaps smaller than the specified value will be closed.
Angular tolerance
Controls the angular tolerance of the generated lines. A high tolerance results in pronounced right angles. This is useful for perpendicular plans.

Generated lines with a smaller angle than the specified value are merged.

Minimum length
Controls the minimum length of a generated line. Lines with a smaller length than the specified value are not generated.
Output options
Attach ortho image and lines to
Determines where the resulting image is generated.

Allows you to switch between Current drawing and Destination file.

Current drawing
The projection is saved to the same file.
Destination file
The projection is saved to the file specified by the Destination file property of the section (see SECTIONPLANESETTINGS command).
Note: You can overwrite a previous file or create a new one.
Attachment point
Determines the insertion point for the generated image.

Allows you to switch between Section plane and X-Y plane.

Section plane
Attaches the projection on the section plane.
X-Y plane
Attaches the projection flat on the X-Y plane.

Select this option to align projection with any generated section block.

Options within the command line

reMove old
Defines whether to remove or keep previously added images or lines.
Yes
Removes previously added images or lines to the section.
No
Keeps previously added images or lines to the section.
