Because of increased accuracy in the new solid modeler, AME models may
look slightly different after conversion. This difference is noticeable where
the previous version of the solid modeler identified the surfaces of two different
shapes as so close as to be considered in the same plane. The new solid
modeler’s finer tolerance may interpret these surfaces as being slightly offset.
This phenomenon is most apparent with aligned features such as fillets,
chamfers, and through-holes.
Holes might become blind holes when the new modeler, with its much finer
approximation capability, interprets what was once a through-hole as being
slightly less wide than the solid. Typically, the length of the remaining solid
material is the difference between the tolerance of the previous modeler and
that of the new modeler.
Likewise, updated fillets or chamfers can occasionally be placed slightly below
the surface, creating a hole through the solid, leaving the original shape
unaltered. Also, drawing fillets or chamfers slightly above the original surface
creates an uneven transition between the solid and the fillet or chamfer.
APERTURE
Controls the size of the object snap target box
Command line: aperture (or 'aperture for transparent use)
Object snap target height (1–50 pixels) <current>: Enter a value (1–50) or press
ENTER
Object snap applies only to objects inside or crossing the object snap target
box. The APBOX system variable controls whether the object snap target box
is displayed. The number of pixels you enter using APERTURE controls the
size of the object snap box. The higher the number, the larger the target box.
You can also change this setting in the Options dialog box, Drafting tab.
