This issue fixed in CGT 1.1
When translating a DXF file through CGT to another file format you may get a bomb. This may occur when the file is saved from a program that can save an "objects only file" or an "entities only file." You can tell if the file is an "entities only" file if you open the file with a text editor and the first four lines start with:
0
Section
2
Entities
If this is the case do a find for the word "Insert." If an insert exists within the file, then the behavior may be caused by the following:
1. The insert that was saved out refers to a block or library object that should have been saved in an area called "blocks" in the DXF file file.
2. If the software which saved the DXF file did not save out the blocks section, then the file is saved out incorrectly. You will find this to be true when an Auto CAD user saves a DXF file using the "entities" option.
