ACIS Writer
The ACIS writer allows developers to export B-rep data from Exchange to ACIS. The file extensions that you can create when you export the data are:
- .SAB
- .SAT
Assembly
ACIS does not support the concept of an assembly and as a result we flatten the assembly before we export it. This means that all the parts in the assembly will appear as sibling parts. The transformations and coloring will be honored such that visually the model should match the source data.
B-rep
All B-rep data is exported with each surface and curve being approximated to one of the following types:
- B-spline surface
- Cone
- Plane
- Torus
...and curves to one of the following:
- 3D curve
- Ellipse
- Line
- UV curve
Visualization
This format does not support a tessellation representation.
Views
Views are not supported by this format.
PMI
PMI is not supported by this format.
Miscellaneous
The notion of hidden objects does not exist in ACIS. The usual workaround consists of forcing the visibility of hidden objects to true and exporting them as visible objects. This is enabled by default with the A3DRepresentationItemExportToAcisBuffer() function, but is not possible with the A3DAsmModelFileExportToAcisFile() function.
