Code follows:

partsName = {
  "1.stl", "2.stl", "3.stl", "4.stl", "5.stl", "6.stl", "7.stl", "8.stl", "9.stl"

robotPartsGraphics = Import[#, "GraphicsComplex"] & /@ partsName;


enter image description here

and now, I want to remove the "triangle" line from the picture. What can I do? (Comment: CAD product, format "stl" -> contains GraphicsComplex data.

I appreciate Szabolcs's and Kuba's advice, all can work successfully! add EdgeForm[None] in last code sentence. The successful code is: Graphics3D[{EdgeForm[None], robotPartsGraphics}].

Thank you again!

    $\begingroup$ I do not understand what you mean by "triangle line". Try Graphics3D[{EdgeForm[None], robotPartsGraphics}] $\endgroup$ – Szabolcs Aug 31 '17 at 8:36
  • $\begingroup$ Thank you very much! i means the "connect line" in function "graphicscomplex ", like the black connect line in picture $\endgroup$ – Ben Aug 31 '17 at 8:50
  • $\begingroup$ Can you respond to my suggestion above to confirm if I understood your question? $\endgroup$ – Szabolcs Aug 31 '17 at 8:54

  Import["ExampleData/seashell.stl", "GraphicsComplex"]

enter image description here

  • $\begingroup$ EdgeForm@None can work successfully! you code is more concise than me! thank you very much ! $\endgroup$ – Ben Aug 31 '17 at 9:11

    $\begingroup$ EdgeForm[] works as well. $\endgroup$ – J. M.'s discontentment Aug 31 '17 at 9:47
