Parameters that control 2D line drawing

Detect walls
When checked, lines representing walls will be generated with the raster image. When unchecked, only a raster image is created.
Search area
  • Distance from plane: detects walls in a given radius from a plane. This option is often used to generate vertical sections.
  • Across volume: detects all walls in the point clouds. This option is often used to generate floor plans.
Wall distance

Controls the search area for wall detection.

Note: This option is only available when ‘Distance from plane’ is selected.
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 will result in pronounced right angles. This is useful for perpendicular plans.

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

Minimum length
Controls the minimum length of a generated line. Lines with a smaller length than the specified value will not be generated.

Parameters that control the generated raster image

Pixel size

Controls the pixel size of the generated image.

Note: the pixel size is in model units. Higher pixel size results in a lower resolution, resulting in a faster process.
Attach projection to
Determines where the resulting image is generated.
Same.dwg
The projection is made in the same file
New destination

Creates a new .dwg file to make the projection.

Note: You can overwrite a previous file or create a new one.
Projection resolution
Finest
Produces a sharp and detailed background picture.
Adaptive
Produces a less detailed and softer background image.
Attach point

Determines the insertion point for the generated image.

  • In-place: places the lines and image in the same location and orientation as the sectionplane.

  • X-Y plane: aligns the section with the X_Y axis.

    Note: The section can be edited in Top view as a regular 2D drawing. This is practical for vertical sections.
Over-write old projection file
When checked, the existing projection file will be overwritten.
