I was trying to do a wood trail map (sign) by importing the map as background and tracing over the paths with polylines. When I try to do v-carve on this the labels (text) show up in the simulation but the polylines are completely missing.
A V-carve can only be applied to a closed region / path. That said, a polyline is not that useful in Carbide Create since the app will automatically close the toolpath by returning to the origin point at the end of the path via a straight line.
If you’ll post your source file, we’ll gladly look at it and see what can be done with it.
