I am find some odd behaviour selecting for helix path.
IIRC I selected the upper two ( congruent ) faces and went on the define the tool , depths etc in the UI.
I did not notice any anomalies at that time but I may not have noticed it was lining up on two holes not all four. I did check depths in std_RightView but again may have been focused on depth and failed to notice it did not give a path on four holes.
I created two drilling paths which show the same problem. I noticed something was wrong when I ran the backMtg-centres path on the machine and it snapped the centre drill in the work piece.
I went back to inspect the job and found the four hole surfaces where the upper and lower co-axial parts, not the four holes starting on the selected planar faces.
I thought I must have goofed up somehow and tried to correct the baseGeometry settings. I deleted to erroneous lower cylindrical faces and then tried to add ones I needed. The UI won't let me select Clone006.Face17 and Face8 I need, so I tried selecting the upper circular edges Edge25 and Edge8. NO path. Ah, maybe I need to select the lower edges: Edge52 and Edge30. NO path.
OK, I use Reset button and let FC work it out automatically. HUH? I still get the four concentric holes, not the four holes in the upper surface.
Never mind, it's a bit odd, I'll try editing the BaseGeometry entries. DblClick and edit, Face17 and Face8 .... Apply .... Hang on, not getting the paths. I select the entries in BaseGeometry to check the highlights in 3D view. They are picking up the lower concentric holes NOT the new faces shown in the UI.
I OK out and come back into edit mode and see the faces have reverted. Apparently you can edit the BaseGeometry entries but this is ignored by Path WB. It just does what it wants.
There seems to be something about the geometry of this part which is confusing the selection algo and it is being particular refractory to any manual corrections.
If I create either a new helix or drilling path I get the same results. It seems impossible to get paths on the two rear holes in this part !
Can someone confirm what is happening?
TIA.
