For v GROOVE OR CNC milling create a leyer exclusively for the data just for these functions. V-groove will be just straight lines, it is important to specify minimum web and angle of v-groove. CNC, I recreate the exact cutting path (paths) I wont, representing them graphicly using a line width of the same size as the diameter of the tool I wont the manufacturer to use, I can then see any problems and easily add brealouts etc. This I do in 2D CAD and import to Cadstar as a DXF.
Create macros to change track widths then add these as a macro toolbar, set it up on all systems then as engineers add connections they can add it with the right track code adding more valuable information to the schematic?layout interface.

Lost_dude, how would you route 2 segments 180 degrees to each other:smile:

V-groove angle, as the tool used to create the v-groove wears down the angle increases usualy within the range 30-45 deg, as the angle increases the gap at the top of the cut gets wider, this can cause problems on dense boards, and make it harder to get good registration when using the "bacon slicer" to de-panelise the PCB.
Personaly I hate v-groove, it is one of the most inaccurate and stressfull (for the components) ways to de-panelise PCB's. It does have its place though, for the lower end of designs, I've designed numerous PCB and panel schemes that have used v-groove, and experimented both with panel sizes etc to get the most out of this method of de-panelising.
The WEB thickness is how much PCB material is left after the v-grooves have been cut, to little and the panel will sag through the various heat profiles during assembly, to thick and the de-panelising bacon slicer will either not register or strugle to cut the remaining material.
