ODB++ Import Options

Arc Precision:

The maximum error allowed when calculating points on an arc.

Default:   120 segments per 360º 

Match Closest NC Tool:

Some ODB++ drill layers are incorrectly created by PCB Layout software - which do not include "tools section" (defines tool diameter and other properties). When checked ACE will create and assign a tool number for each unique pad diameter found on NC layers (within a tolerance of 0.05mm).  

Default:  Unchecked

Convert Surfaces to Polygons (with cut-lines):

Breaks down complex surfaces into Polygons.  The ODB++ surface  is similar to a Solid Hatch in AutoCAD.

Note:  This feature can be very time consuming and only recommended if there display are issues with surface.

Default:  Unchecked
