Build panel milling with skill

Assuming that you are using 17.2 you should use axlDBGetShapes:

outlineShape = car(axlDBGetShapes("BOARD GEOMETRY/DESIGN_OUTLINE"))
polygon = car(axlPolyFromDB(outlineShape))

Hi Dave,

Thanks for your reply

after translate it into polygon, i can use expand poly right?

exp_poly = (axlPolyExpand polygon 1.6 'ALL_ARC)
axlDBCreateShape(exp_poly t "board geometry/Ncroute_path")

got this error: W- *WARNING* (axlDBCreateOpenShape): Object should be either an r_path or an o_polygon -

axlPolyExpand returns a list so you need to process all the elements in that list (probably just one)

Wonderful, with car i manage to get it..FINALLY, thanks you so much Dave..

but how about segment? currently we still using outline (line segment) instead of design_outline.

Hi

Since you don't know if the segments are in order you would first need to get them ordered so they form a closed polygon. 

From there you can create a temporary shape that you can expand to get your milling path and then delete the temp shape. 

This is exactly the reason that outline was changed to design_outline - the outline layer was used for all kinds of things and there was no way of telling if it was a closed polygon or not, as an example the closed polygon form on design_outline is actually used when you do zones for flex-rigid PCBs but thats another story.

Best regards

As Ole points out, you should only do this with shapes. If you must use the outline layer then I suggest that you use Shape/Compose to convert the line segments into a shape before you start. It is bad practice to have anything on the outline layer that is not a shape.

Thanks Ole and Dave for your input..=)
