I have the last nightbuild of cSurvey.
Here are the operations I did:
I exported the sketch from TopoDroid as *.csx
I opened the *.csx file in cSurvey
I exported the image as *.svg from cSurvey.
When I try to import it in Adobe Illustrator I get the message that is showing in the first PrintScreen.
And after, when is placed in place, it looks like in the second PrintScreen, with the small instance on it...
In addition, this image (exported as *.svg) is different in size as the other exported as raster (tiff, jpg, etc) even if they are at the same resolution (96 dpi).
I hope that this explanation to be more relevant. Thank you!
