I'm fairly new to blender. I want to design a somewhat complex model, that I can later print with a 3D printer and possibly use for WebGL as well. Before I start, I wanted to clearify that I'm actually joining the meshes together properly and that overlapping and duplicate lines are acceptable.
I'm using the 'honeycomb' mesh that comes with blender as the base:
I applied the array modifier to the mesh and set the X offset to 0.765 so it lines up properly:
From what I understand, the blender instead of 'extruding and copying' the honeycomb pattern, it 'stacked and copied' the pattern, in other words - the line that connects the original honeycomb mesh to the honeycomb copies is actually two lines overlapping each other at exact location.
In edit mode, if I 'click' once select and drag the points around, I can see there are duplicate lines:
Is there a function where Blender can remove this duplicate lines and recreate the mesh by 'joining' the points 'cleanly' and removing the duplicates so it's connected cleanly like the original honeycomb mesh?
My question is: Will this kind of mesh cause me any problems if I would want to 3D print it or use it for WebGL? is this considered bad design or is this mesh perfectly acceptable?
Another example, if I take 2 cubes, overlap them and ctrl+j(oin) them, is this a proper model, or do I need to redesign it, so there are no overlapping faces? Thanks!
