COLLISION DETECTION
79
The Collision Detection checks, if any two or more parts in the project touch
each other. If a collision is detected, the colliding sections of the parts are
marked yellow. The function can be accessed in the toolbar, in the Edit menu or
by pressing Ctrl+K. Users can choose a tolerance of 1mm or 2.5mm, defining the
raster size (figure 5.27). netfabb divides the whole three-dimensional space in raster
cells of that size. Each raster cell occupied by more than one part is then marked
yellow (figure 5.28). Thus, with a tolerance of 2.5mm, parts with a distance of up
to 2.5mm may be marked as colliding. However, while a bigger raster makes the
collision detection less precise, it saves calculation time.
Figure 5.27: Choose a tolerance of 1mm or 2.5mm.
