Import Options

Import Options
This dialog controls  how Ennova handles the import of data

Perform Auto Repair on Import

1. Perform Auto Repair on Import
If this box is checked the repair command will be run automatically


2. OpenCascade
Ennova can import geometry using the open Cascade library. This option has been deprecated and is no longer supported. The replacement library is hoops

Use Existing Tessellation

3. Use Existing Tessellation
Nurb based  geometry is normally stored with an exxisting tessellation created by the creating CAD package.If the nurb data is corrupt and cannot be read or fixed successfully then ennova can use the existing tessellated data instead of the underlying Nurbs.  Normally it is more accurate to use the Nurbs themselves though and some loss of accuracy may occur here

Hoops Exchange

4. Hoops Exchange
Hoops  is the default nurb library for importing / translating geometry into the Ennova Kernel. Normally this is the setting that should be used

Use Nurbs

5. Use Nurbs
Checking this box will read the native nurbs via  either Hoops or OpenCascade.   Note if nurb data is used the existing tessellation in the CAD file is not and any further  tessellation is performed by Ennova

Group Source

6. Group Source
This option controls how ennova places the geometry in different groups. Groups from file contents attempts to place the geometry in group names that exist in the file. Otherwise  one single group can be created for each file with the respective file name as the group name.


7. ST
STL is basically a list of unconnected triangles with no Topology information. So STL is handled differently in Ennova. This data can also be locally set in the File Open menu and is described there
