Surfaces - Check to include surface definitions. Any offset surfaces that have used tooling parameters to define the shape are ignored. Only geometric offsets are valid.
Dimensions - Check to include dimensioning information.
Output Surfaces as Nurbs - Check to allow the conversion of EdgeCAM surface entities to NURBS. Trimming and extensions to the original surfaces are applied to the NURBS surfaces. If any of these surfaces are re-imported to EdgeCAM, they will be imported as B Spline surfaces. The EdgeCAM surface entities not explicitly supported by IGES are:
|
Joined Surfaces |
Extended Surfaces |
|
Coons Patches |
Flowed Surfaces |
Note that for flowed surfaces only, the conversion is approximate, and is governed by the Conversion Tolerance parameter.
Conversion Tolerance - Specifies a tolerance to use when generating a NURBS from a Flowed Surface. This defaults to the system machining tolerance.
Minimum Resolution - Specifies the minimum mathematical resolution for the data. If a gap between contiguous entities is less than this, it is considered to be closed. The default depends on the units used:
|
Metric: 0.000001 |
Inches: 0.00000004 |
Draft Standard - The standard to which the drawing was produced. The available options are:
None - No standard specified. This is the default
