I am trying to design a dual color model to 3D print and know that I need 2 STL files (one for each color). As a test, I took an egg/oval shape and then applied a displacement using a black and white texture. In other words, I used the applydisplacement to "carve/engrave" into the egg surface to get grooves in the egg surface. My goal was to obtain the grooves or carvings to use as the 2nd color STL model by Boolean difference of the engraved egg with the original egg.
I have attached a file that has the overlapping eggs in the center. The engraved egg is shaded yellow and the original (before applydisplacement) is not colored.However, Boolean operations seemed to fail on the 2 center aligned eggs. Remember that my goal is to extract the valleys/grooves from the original egg by subtracting the grooved egg.
Moreover, as I did further boolean tests against the grooved egg, I realized that the success boolean operations treat the grooved egg as if it were the original egg prior to the applydisplacement.It would appear that the results of the applydisplacement doesn't really result in a grooved complex nurbs object for boolean operations at all.
Can anyone suggest a workflow to get what I want from the grooved egg with the applieddisplacement? (goal is to get 2 STLs, one of the grooved egg, and one of the Grooves alone. Both STLs have to fit together like a puzzle piece to create the dual color model to 3d print).testdualcolor.3dm (4.6 MB)
