I have just uploaded a new version of the app and I’m happy to say that each DXF you have posted in this thread works as of this moment !!! I’ve also added scaling and if your DXF doesn’t have a scale, the app takes your preferred unit system from easel (inch or mm).
@Kel : your bird stand will now have it’s beautiful round circles.
@DonnieSmith : your error has been fixed and your file works as of this moment.
If some one does encounter some other issues, please don’t hesitate to post your DXF here and I will do my best to resolve it as soon as possible.
