Hi. I have a DGN file with exploded symbols (img 1).

image.pngI need to make one line from these 3 following lines and fill the gaps between these lines.

Firstly I use Snapper (snapping tolerance set to 2 because gaps are about 1.7) and then LineCombiner. It works well with my test data but at real DGN it works wrong (img 2). I do not want involve marker ("circle" with short line) to process.

imageThanks.

  • Are the lines and markers on different layers? Either filter by layer name or use a Group By on the layer name (igds_level_name) in the Snapper.
  • Are the markers dissolved cells? Either filter by cell id or use a Group By on the cell id (igds_cell_sequence_number) in the Snapper.

Lines and markers are in the same layer. "circle" entity is ellipse so these I can remove, but not short lines.

(I apologize for grammar mistakes but English is not my native language).

If removing short lines is an option, you could use a combination of a LengthCalculator and a Tester to filter them out. The length will be given in the same units as the input data coordinates, e.g. millimeters.
