Hello again. I have a question but first will explain what I am trying to do. I just revived a 3D printer and I am trying to use BOB CAD to make things to print like knobs for selector a switch.
I create the object and export it as a .STL file then open it with a program called KISSlicer to create the G-code for the 3D printer. The problem I am running in to is that some of the surfaces are showing up as a inside wall facing out of the solid.
What I need to know is there a way to tell a side of an object if it is a inside or outside facing peace?
In the pix the red area shows the surface that is facing the wrong direction. The second is the example of the finished product.
You would need to check the surface normals inside of BobCAD. You would need to do this before exporting the file out as an STL, which then becomes a 3D image, rather than actual geometry. You can view surface normals by going to View/Surface Normals. IF the normal is not facing away from the surface you will need to reverse it. This can be done by using Utilities/Reverse Surface Normals.
