Problem when exporting to DXF with version 3.0.13 and 3.1.5 Pix4Dmapper

Can you help me? With the new version 3.0.13 and 3.1.5 Pix4D I have problems exporting polylines to DXF format, the exported file has errors. When I try to open it with AutoCAD “read error, invalid or incomplete DXF input” appears. This did not happen with previous versions.

Excuse my spelling, I know little English


Omar I also had the same problem. I saved the polyline as shp file and it worked.



Thanks John. I could continue working. I hope that our friends support help us clarify or resolve the problem. 

This is a big problem for me also; i hope they resolve this in a short time.

(sorry for my english…)

This was covered in the technical release notes for version 3.1.7

From the document-
