Remove duplicate vertices - important for gcode generation
1. Hit Tab to enter Mesh Edit mode
2. Hit A to select all nodes (everything goes yellow and purple)
3. Type W6 or select Mesh -> Vertices -> Remove Doubles
A few UI tips:
- the 'A' key toggles between select all and select none
- the right key is how you select objects
- the tab key will take you between object and mesh mode
- holding middle click will allow you to move your view. scrolling it will
zoom.
- the num pad keys will give you good default views if you get lost
- the 'X' key will allow you to delete objects, like the default cube when you
open blender
Find non-manifold points
Non-manifold points are points that just don't make sense in the real world.
These can be hanging points, internal surfaces, holes, zero-thickness walls,
etc. Unfortunately there is no way to automatically fix them in software. The
best you can do is to identify the problems and then attempt to fix them.
1. Hit Tab to enter Mesh Edit mode
2. Hit A to deselect all nodes (everything goes gray and pink)
3. Select Select -> Non-Manifold
If there are non-manifold points, they will be selected. If nothing happens,
you're golden. If there are problems, then you can see what's wrong and attempt
to fix it.
