How to convert Shapefile (SHP) to DWG

خطوة بخطوة

1. 1Collect the whole set: .shp, .shx, .dbf and ideally .prj. Without the .prj you are guessing the coordinate system.
2. 2QGIS (free): add the layer, set the project CRS to your CAD grid, then Project → Import/Export → Export Project to DXF, and open that DXF in AutoCAD to save as DWG.
3. 3Civil 3D or AutoCAD Map: MAPIMPORT reads SHP directly and can map attribute fields to object data or block attributes.
4. 4Decide how attributes should arrive — as object data, as block attributes, or as text labels — before exporting; retrofitting them later is painful.
5. 5Check coordinates against a known site point: large easting/northing values can also trip AutoCAD's precision if you do not move the drawing to a local origin.

أمور يجب الحذر منها

• QGIS exports DXF, not DWG; the extra save-as step in CAD is normal.
• Curves in GIS data are stored as dense vertex strings, so expect polylines rather than arcs.
• Layer names come from the GIS layer or an attribute field you nominate — set this up once per project.
