A file export that was about 66KB on 4.12 is now closer to 3MB.
I am trying to find a developer that would know the answer to this question Glen - as soon as I have an explanation I will let you know
Also note: when exported through "Field Data" -> "Create Design" , C3D 2019 will not open the file yet the data collector will. However, when the same line work is exported via:"Export" -> "CAD Tab" -> "DXF exporter" (dxf_2000) C3D 2019 will open the file. I also concur that the exported files seem "bloated" compared to previous version exports. I've also reported this issue through my SiTech dealer.
I ran my own tests on this issue and found the following
1) The DXF File output from TBC v5 are for sure much bigger than in BC-HCE 4.12 - I have created test files and sent them to support for review and comment
2) The issue that people are raising relating to DXF File Exports using the SCS900 workflow not opening in or opening in and freezing in AutoCAD I have not yet been able to reproduce that, I am going to take a look at Pat's Data next to see if I can recreate that with that data set.
