Thanks for all the Info !
Yes we can project onto a 3D Now:)
AND yes there is a Dome/Dish section in the clip art provided with VCP8
Think we'd have to either extend the cut beyond dome with the offset feature(NOT totally uniform though) OR create a boundary in "Modeling" and clear it first OR best so far for me is to create a perfect circle and then use preview to cut into Dome just enough at tab height to eliminate all visible ridges.
Because the "Dome" isn't PERFECTLY centered, I'd probably draw one half in a very small square area in material set-up and use the "center in material" rather than centering on design for everything, and THEN change my material set up and mirror.
THIS is just for others who are Lurking and NOT you!
That stepping over thing probably explains this weird mark on ALL my "Herd of Owls" I carved in lower left quadrant? It was bugging me as it's perfectly smooth(no"ridge"?), BUT it's visible.(hoping one of my pics shows it--Very faint and depends on light).
Thanks for giving me a place to look for it!
I did "discover" something interesting with rectangular "Owls". Had it set to "Machine beyond boundary" .01" in proto, and it started in center and then worked out from center by the stepover evenly which was GREAT as stepover was small and could use the Offset toolpath. BUT when I went to using EXACTLY the Owl boundary, THEN it started in the center again, BUT it started hopping around in the deep sections which was 2Xdiameter of bit
Swapped back to .01"beyond Boundary, and everything was Hunky Dory again.
Dad will just have to be satisfied with being "impressed" with "Owls" for the moment-Too darn Busy
