Hi Mark,

I use QCAD and have found it to be quite good. I bought the version with the book and it works for me but I had the same problem as you - double cutting entities. I discovered that there were copies of entities stacked up below the ones I could see. I've no idea how they got there but I think if it wasn't me drawing them twice it was QCAD adding them when I copied several entities together to another layer. This might (or might not be) a glitch in QCAD. I don't know. You can find them by clicking on the entities that cause double cutting problems, deleting them and seeing if there is another entity below that and so on. If there is nothing below the entity then just bring it back (undo). That cured my double cutting of entities problem.

However there are two version of QCAD - the bought one and the 'free' one and I couldn't get the free one to work properly so you might need the bought one...

I am using Ribbonsoft's CAM package and found that it converts everthing well and even gets the start position right most times but it won't convert closed elipses (ovals) so there is another problem and I don't know which package it's in.

I'm looking for another CAM program myself.

Hope that clears up at least one problem.
