Assign custom layers to specific geometry in .dxf

[sbulowPFMJG]

Context: I many large assemblies of wood cabinets. These cabinets are assembled with dowels, locator pins and screws. The machining involved 95% of the time is: an outer contour cut and several boring operations. ( 8mm, 5mm and 1mm)

Problem: My CAM software is able to import the part with the machining pre applied, so long as the name of the layer is pre-set with the machining info. ie ( TCHWOB0TCH16660 ). The outer contour will always be the same, but the inner features will need different layer names for the different bore hole sizes. 

Question: How can I automate the assigning of layer names to holes of certain sizes. All holes of 5mm = layer name X5X, 1mm = layer name X1X ect 

Thanks,

Well, I can't say I know 100% if it's impossible in Inventor.

But the export of Flatpattern to layers, only looks at a predefined set of objects: inner profile, outerprofile, arc centers, bendlines etc etc.

Since the 3 circles of different diameter will export as 3x an inner profile. I don't see a method to distinquish them in the DXF translater.

But with programming in Autocad I think this could be an easy task.

Like a post-processing of all DXF's in a folder. Open with autocad each file, select all circles with diameter and change layer or color. Perhaps ask this question also on that forum.
