#5210 closed defect (fixed)

DXF linestring export with Z not correctly imported in ACAD

Reported by: koestli Owned by: warmerdam
Priority: normal Milestone: 1.10.1
Component: OGR_SF Version: 1.9.0
Severity: normal Keywords: dxf

Description (last modified by koestli)

Linestrings are exported as LWPOLYLINES; if the points have different heights, the import in ACAD is incorrect, because ACAD (and others) expect only one height. POLYLINE entities should be used in these cases. The problem seems still there in 1.10. Unfortunatly I can add sample code based on 1.9.0 only.

Patch applied with minor reformatting in trunk (r26353) and branches/1.10 (r26354), with a bit of testing too. Thanks

A bug report has been done recently in after applying your patch. Perhaps you could check if you encounter the same issue as the reporter of #5217 ? Looking at , it seems that a dummy point with pairs "10 0" and "20 0" should be written for a POLYLINE. The Subclass marker should also likely be set to AcDb3dPolyline.
