I have taken an Additive Cylinder.
I have applied a Thickness tool to it.
It works.
But there are some intersections in the Body... Is it true? Why?
Or, are there some troubles with normals?
I have exported my Body to STL and opened it in Blender. And I have seen some problems... Why?

Re: Part Design: problems with Thickness tool
The interesting question is how you created the STL. Here is an STL I created using your model:
It works fine for my 3D printer. I don't have Blender and did not understand what your problem is with it.
From the PartDesign point of view, your model looks good.
Re: Part Design: problems with Thickness tool
File -> Export.
Your model behaves like mine.Here is an STL I created using your model: case (Meshed).stl
I have printed it. It was fine.It works fine for my 3D printer.
See a picture below...From the PartDesign point of view, your model looks good.
Why are triangles at the picture (Transparency property is 50%)?

Re: Part Design: problems with Thickness tool
Probably just some display artifacts. Onscreen everything is actualy triangles...

Re: Part Design: problems with Thickness tool
I am trying to understand: are these artifacts normal?
Hmmm... a strange behavior in Blender is not all time...
The models were imported with a 1000 scale... when I had scaled them to 0.001 the Blender view has become fine!

Re: Part Design: problems with Thickness tool
These are just display artifacts. They occur with certain settings. For me it often helps to use e.g. 51% transparency or to to try out if in the preferences -> Display the option "Use OpenGLo VBO" improves the situation.
Concerning the STL creation, you should do this via the Mesh workbench because then you can control the mesh deviation from the original model and thus also potential display issues in other programs like Blender.

Re: Part Design: problems with Thickness tool
Now I don't understand you. I just said that you should use the Mesh workbench to create the mesh because there you can adjust the mesh parameters like the maximal angular deviation from the original object. The better the mesh the less the display artifacts.
