I am ALSO getting the same error when i open X5 files and try to run the Verify. This is fixed by reselecting the tools for all operations...quite counter productive Any word on when this issue will be fixed? Not being able to verify surface operations is a major risk issue for me.

yes and it is also set as my default library in setting>configuration

It also fails if i create a new tool instead of using library tool. Now the toolpath "looks" fine, it just that i can't verify my surfacing operations

Using X7 SP1 and this was a fresh program created from scratch in x7. I am having the issue on all new programs that have a surfacing op(flowline). I notice that if i have a non surfacing OP prior to creating one, the simulator gives me the error OR it runs with the tool from the previous OP. @Gcode I have a custom tool library that i made by copying all my x6 tools to a new x7 .tooldb file

I am getting an error when opening some surfacing operations in the new verify. Anyone else have this problem? Its driving me nuts lol.
