dbvoght,
I think LazyCam is intrepreting the arc's as straight lines because they are not true arc's but rather a spline which
has 4 equaly control points, one at each end of the arc and two between. Some of the straight lines extend beyond
the arc's. I know nothing about Coreldraw but do suggest you dump it and purchase a $30 CAD program as you will have other problems later on because of a paint program.
Sorry to sound a little harsh, but best advice I can give you.
PS: I checked it in 4 different versions of two CAD programs and they all told me the same thing.
Maybe you can try something different in Corel and see if the import is better. For a high level understanding on the DXF importing take a look at the DXF Appendix in the LazyTurn manual which is located in Members Doc's.
