I use the nesting tool path a lot of the time..... I find it works well.. we have a 3m x 2m bed size with a x 10 tool changer and machine full sheet sizes every day..... although I may have many tool paths on several layers, there are only few machining types. For example, cut out layer,, 8mm drill layer ,, pocket layer,, 5mm drill etc. From these I may only use 5 tools, as one cutter may have a number of layers to cut.
There are many more for all different assemblies that we may do and endless drawings, But providing you draw with the same layers,, and then importing your saved tool paths it will delete the tools you don't need from your saved toolpath... If one does get through, and when you calc all the toolpaths it normally will give you a error, just go down the listings of toolpaths and delete the unticked boxes.
Before I start drawing I have a saved template drawing, I copy into a new drawing, with that all the named and coloured layers are copied with it. Then I just draw.
I do find the template gadget very useful also.
Example..... if I draw a 10mm pocket x 5mm deep on a green coloured layer and I have a toolpath that is designated to see's the green layer.......therefore I can draw 18mm .... or 30mm pocket on the drawing and the toolpath will cut them all at 5mm.......... If for example there are a few pockets I need cutting at 10mm deep, I duplicate the original toolpath by right clicking and highlight the amended pockets and change the depth of cut.....far quicker than making a new toolpath from scratch.
Is there anyway to simplify your drawing????
There are a few things I would like to make drawing faster..... but that's for another day....
Anyway......just on another note... See the way I threw a few metric measurements in there just to confuse everyone..........Ooooo! don't get me started!!
