I've imported some of line shapefiles drawn in AutoCAD, so now I have one shapefile with multiple features (one feature is one line drawn in AutoCAD). How can I merge all of these features into one single feature?

  • What I know that Polyline objects should be connected together if they are one feature. Can you explain the reason for doing that or show a screenshot so we can give other suggestions ? – Shiko Apr 24 '17 at 8:17
  • @Shiko Features are connected and they create one line that is my shapefile, I'm just wondering how can I do it, there is no special reason for doing it, simply I dont want to have 27 features in one shapefile, I want to merge them so I can have one. – Стеван Стојиљковић Apr 24 '17 at 8:34
  • Another question, how can I merge specific features in one shapefile, for example, to merge only features that are spatialy in specific (polygone) feature of another shapefile? – Стеван Стојиљковић Apr 24 '17 at 8:39
  • I suggest to import them as cad layers, coz autocad have not so much operation in outside layers like (shp,mdb,dbf...) – Florjan Apr 24 '17 at 8:54
  • You can use join lines in Autocad as in this link knowledge.autodesk.com/support/autocad-lt/learn-explore/caas/… – Shiko Apr 24 '17 at 9:20

To merge lines and polylines using Autocad, use Join feature as in below link:

  1. Click Home tab > Modify panel > Edit Polyline. Find enter image description here
  2. Select a polyline,spline, line, or arc to edit. If you selected a spline, line, or arc, press Enter to convert the selected object into a polyline.
  3. Enter j (Join). Select one or more polylines, splines, lines, or arcs that are located end to end.
  4. Press Enter to end the command.
